Best Heads for 347 Stroker

[justinkendell]

Thanks everyone for the info and debate, but I have decided on the Vic JR's.

 

[5spd GT]

5sd, you guys kill me, first i say i want track numbers, and someone tells me there is too many variables, so i will adjust my thinking possibly after i see dyno numbers and still NOTHING.

I said it is up to you if you want to find them. Just the same if you want to talk to Ed. He would laugh at you with the comments about AFR's your making.

Just do a search and you won't be dissapointed.

I agree, i'd much rather see track numbers, but since they don't exist i'll take what i can get.
What i'm saying is i'll take either at this point, dyno number or times, but so i can't find any.

Do a search, ask the pros. Not one pro. Who could I be talking about

When you determine if a head works, you don't try to disprove it, you try and prove it. How the hell do you propose to get proof they don't work at the track like you request? When things don't go the way people plan, they don't speak up.

Lol at that statement. It can go either way.

Your not to good at this

5spd GT - yes it has been a while.. the old 91GT I had is gone and sold.. I had a 98 T/A m6 for a while and sold that and I'm back.. in an 88GT

Yeah I had to sell a "newer car" as well. I do miss it though I love my fox.

dont have AFR envy.. but if I had the money I wouldnt mind some 165's for the lil 302..

Nice

as always I disagree with your way of thinking when it comes to engine building... I cant knock the motor you got because it is much more then what I have at the moment.

Would you care to explain? I have been in more unstreetable combo's than mine and I just don't like the low end loss, bad idles, low vacuum, etc. Though they do outrun me at the track. Plus I like getting 24mpg.

I'm assuming you like to go more aggressive with your 302 setups. I have .560 lift (semi-healthy on a 302) on my cam.

Just remember, if one has more done to the engine that does not mean that they are "smarter" or more knowledgeable. It can go both ways. Just because you have less mods on your car doesn't mean your car means any less...

dyno numbers ? track times yet?

I ran 8.4 in the 1/8th mile with some things wrong with the car. Getting very close to getting those fixed and hitting the track for a better time/mph (86.xxmph).

You took that comment out of context. Their is a difference betwwen a street car and a track car with a 347. Should I ellaborate on that?

I don't care if it's on the track or the street, if you don't see 400rwhp, mid 11's, or 120mph timeslips, someone screwed up. (one of the 3 will do)

You are the typical stangnet member, what you have is great because you have it, not because it really is. This site takes brand loyalty to a whole new level.

All i said was afr 185's are unproven, not that they are better or worse than anything else.
At least if you don't want to prove it to me, prove it to the guy that made the post, people suggest heads to him and they don't even have any experience or proof.
Just internet hype.

Lol...that is funny.

Actually, I did TONS of research and found out which one is the best for my goals. So what about brand loyalty? None of my friends own these heads, it was all by hear-say...this dang internet

Your the one preaching on FRPP 347's and big daddy. But you don't show brand loyalty do you?

Your posting to get these peak numbers and big track times. That should not at all be the only factors on selecting heads/combo. Way off there my friend. You suggested it, I doubted it. Very simple.

Please do because from what I'm understanding your saying people are building strokers not just for power or better 1/4 times. Whats left? Don't even say reliable gas savers. If anyone ever builds a stroker for better fuel economy or reliablity then they're in the wrong league. Whole purpose of a stroker is more cubes = more power = better 1/4 times.

Again, taken out of context. Their are hundreds of daily driven 347's out there that like their a/c, power steering, nice vaccum, driveable idle, manageable powerband, etc. You can sacrifice some of these commodaties to get faster...

That is the point.

I never said to get good gas mileage, though you can make combos that do get better than others.

I never said to get more mileage, but you can make 347 combos that can last longer than others by using different kinds of rings/rod ratios/internal rotational weight. It's all in what you want and how you want to spend it.

Anymore?

 

[2000xp8]

I preach the FMS 347 as money saving, time and cost effective. You get the engine in your hands in days, built with quality parts, and it's been proven in person to me that it works. You go by what someone tells you on the phone or on the internet.

FMS 347, Spend less get more. And get the reliability of a street car you love so much.
Afr's are spend more get less or equal.

No way is the FMS 347 better than say a built r or dart block, but i know this.
I tell people that it works, because i see it.
And you tell people things work because ed curtis tells you they do, that's the difference between us.

 

[dstanggt50]

I've never had any exp w/afr's, but I remember reading in a mag when they put the 185's on a 392 stroker, and it gained around 75hp, but it was compaired to gt-40x's, I would think all of those heads would be good choice, personally if I ever built a stroker the new cnc tfs heads look nice.

I just prefer to go the cheaper route to get faster ..

yeah.. I do go rather agressive on all my 302 setups and the loss of low end and lack of accesories doesnt bother me when I get that time slip at the end of the track.. I dont mind sacrificing it in a 17 year old car for a little more edge against the rest of the competition..

hence time in sig on drag radials and stock clutch/shifter'


like this car I'm picking up an explorer motor for .. its killing me to keep it simple ... I'm supposed to just do rockers/springs/cam but it will be much more .. I want to do 11's on a bonestock explorer motor with just a cam swap.. then spray 10s

So do you think I don't go to the track? I'm not a member of a couple clubs? Haven't been to dyno sessions? Don't have friends with these type cars or mods on them?

Sorry, way wrong...lol. If I could only explain

FMS 347, Spend less get more. And get the reliability of a street car you love so much.
Afr's are spend more get less or equal.

What more do you get with the FMS hyper pistons?

So why do AFR's do so good? Just by hearsay? Or what pros show and tell that they can do? Do you think a product would last by just by hearsay? Sadly mistaken about supply and demand and market.

No way is the FMS 347 better than say a built r or dart block, but i know this.

Talk to some pros that deal with those heads and aren't brand loyal like mr. daddy is. Your brainwashed my friend It's cool though...some have a stronger mind and some have a weaker one

Your experiencing AFR envy and quality control. You will get over it eventually. good luck.

Your making not point what so ever. So now you're saying you can't make power with accessories? Most people who have a street car have all these. Does that mean they can't make 400rwhp or run low 11's-high 10's? If poeple want a stroker with all accessories, low hp, and ****ty 1/4 times then why do one? Is this the reason your doing one?

Your not good at this either.

Did you ever want a faster car with your accessories still driven by the engine. I do...and many others

So where did I say you can't make power with accessories? Show me

You can make more power with them removed.

You twisting words doesn't effect me...you need to learn just a bit more who your dealing with, I don't fall for that

Thanks everyone for the info and debate, but I have decided on the Vic JR's.

You'll be happy with them. I would suggest a custom cam as well along with valve springs and set the height correct. Check this link out to see what a victor jr head can do on a n/a pump gas 347. http://www.fordmuscle.com/archives/2005/02/YellowFever/index.php

I'm not going to get into this afr pissing match, but from I have seen, when set up right, the afr 185's work VERY well on 347. The ones I see that impressed me used FTI, Hitech motorsport or AFM cam's. Its all about the total package.

 

[2000xp8]

I'm not brainwashed, i'll use anything that i see works.
BD doesn't only use FMS engines, but he likes them. He's also fond of CHP built engines, and does many custom r,dart block 347's.

The crate motor i have is also not the one with the hypers, based on the fact that if budget permits in the future the rotating assembly can be swapped from my sportsman block to an R or dart.
But the hyper version is extremely useful as a DD, that's why hypers were used in it.

 

[Rick 91GT]

Wow look at what this thread turned into....

I have built quite a few AFR185 headed 331 NA combos that have gone mid 11's on daily driven street cars so they will make power.

Do I like the TFS TW, Victor Jr's, and other sure...they all will work very well but the combo has to be correct. I just finished using a AFR205 on a big bore 347, "364ci" and I'm looking at 10's in a car that has a converter set-up for N2O.

Look at how many high 12 sec stroker combo's you see, it's all in the combo. Any properly built mild stroker combo should go 11's, a purpose built combo can go low 10's or quicker.

 

[CoupedUp]

.... Couped up, i'm not trashing your car, but a 331 with afr's should be in the 11's, why haven't you said what your mph is?

You can see my public profile by clicking on my Screenname. Anything you want to know about my day at the strip is there. Again you have to weigh the cars lack of drag traction.

A lot of guys on here boast et's that are unrealistic to the real world. An 11 second car is easily obtainable with a 331 stroker coupe ... but my car isn't set up to run the 1320 ... lying or overexaggerating my power numbers or times does justice for no one.

 

[90mustangGT]

I knew by the word "best" being used in the title of this thread this would turn into a pissing match, and sure enough, everyone is getting wet!

The word "best" is a broad word to be using. What is best for one application might be totally different for another. AFR's are good heads, so are TFS's, Canfields, Brodix... they all make great heads. If you get any of them worked, then the quality of the work takes over. Of course even then if the heads can't breathe due to a restrictive exaust or intake then it really doesn't matter, and if you have the wrong cam, then that can really have an impact on the total performance as well. I dont' care what heads, cam, intake, shortblock, exaust, ect setup you have, if they don't work togeather then the results are going to be very dissappointing. Too small and top end will fall, too big and it will make it a pig. (I made that up; cool? lame?) That all goes to components. Mix small components with big components, and chances are your not going to be going anywhere well.

The delima I am going through is that I want big power and good times, but I want to keep it streetable, I don't want restrictions, but yet don't want to go too big. I swear, building an engine "right" is like building a house of cards, one wrong component can really f' things up.

You wanted links. First one is 530 flywheel hp from a 347 with afr 185s, second is 575 flywheel hp from a 347 with afr 205s.

Impressive.

Not quite the same comparison as here (being carbed, using solid lifters and cam, along with jesel rockers)but still should make about 450 to the flywheel, which is nice numbers.
