Good head for my 306/nitrous combo

[5.0_GT_kid]

DISCLAIMER: I know this is a somewhat touchy subject around here, I am in no way trying to start a pissing match over this, just want to know what would work best for me.

I also know alot of you say it's all in the combo, well I need to know what would be best for my combo.

Anyways, I'm planning a 306 setup that will be used occasionally with nitrous. This car is going to be a daily driver for awhile, then down the road become a weekend car. Also since I'm in Florida, emissions is not an issue. Also I will do some 'recreational" drag racing and Auto-X...but no formal form of competition.

Blue Oval Corral here in Clearwater is going to be buildup of the engine for me, and they suggested a Trick Flow Track Heat intake and a custom cam from Ronnie Crawford. We got talking about heads and Chad, the manager, suggested some Twisted Wedge heads, and I had mentioned I liked what I had heard about the AFR 185 heads.

Chad thinks both the AFR 185 and Twisted Wedges would work well...but I was wondering what you guys here thought. Obviously I have to pick one and want to get it right the first time.

So given what I have told you, what do you think would work best for me? Keep in mind that I will not be increasing the displacement of the engine or anything, so that negates the ability to grow with the Twisted Wedges.

Thanks in advance guys, as always, your help is appreciated.

just get one of each j/k...i think the afr's outflow the TW's a bit, but im not 100%....check out the 94-95 FAQ for flow rates......

EDIT: just checked the flow rates for ya in the FAQ and the 185's outflow the TW's....check it out......

Thanks Mike, I had forget to look at that before checking.

Me either, I'm hoping to at the least, get into the mid 12's with it on all motor.

i am no way saying it doesn't matter, but nitrous does not require a better flowing head to produce the power of the shot you are giving it. nitrous differs from forced induction in that you are not increasing the volume of air into the cyl you are increasing the percentage of O2 into the cyl. for instance a 306 with E7 heads will still make 100hp extra on a 100 shot. a 306 with better heads will still make 100hp on a 100 shot. pick a head based on your n/a goals then add nitrous.

Good post Bimmer, Chad had mentioned this when we discussed my engine but we really didn't go into details. Thanks for elaborating, I have a better understanding of it now

thats what this board is for, i really think a 306 with 185's and a good intake is a great setup and should provide a big grin for a while. good luck and i hope it turns out great!

Thanks buddy, I'll make sure to shoot some videos of the car at the track once it is all done.

not to hijack but a 306 with 185 heads good intake and cam what kind of power will that be pushing im goin the same route and im hoping the motor will be a big change from the 14.9 i run now

Well Chad said I should be pushing 310 rwhp, but I have a feeling he may have been making a conserative prediction there.

Either way, the beauty of the custom cam and the ability to tune with the Tweecer won't be the peak HP so much, but the overall powerband

 

[stang_dan]

nice when i start building im goin to get a custom cam too cause i been told be sooo many people here they make a huge difference.
and my buddy that joined the marines with me who i been helping build his fox bodys and my car with forever sadi i should also go witha custom cam.

also the tuner is it worth it or should i just get a chip burnt but i figure witha tuner i can change it when ever
what kind of tuners are there and where do i get them? turner very new to me. old car carb lol like 2 wires lol

I think a custom cam is definetly the way to go

As far as the tuner goes, I asked this question awhile back and you can view the thread here....http://forums.stangnet.com/showthread.php?t=561976

Hope this is of some help.

Which ever you can get cheaper both will work well on a 306. All though if I was making the call I would lean towards the TH's more of a preference.

 

[stang_dan]

wow taht helped alot im goin to go look at the screen shots right now..
looks i better plan on another 1500 or so for the tweecer and wideband
lol

TH=Track Heats basiclly TW with upgraded springs and 10 degree locks

[stang_dan]

it say on the tweecer site the tweecer rt is only 550 i thought some one said 900 for it

If your gonna go with trickflow heads, get the twisted wedge and not the track heats. You WILL be changing valve springs regardless since your going custom cam, so save your money.

An rpm intake would probably work well. If you wanna make better power and maybe spin it a little higher, i'd consider an rpm II or a holley.

Either head will be fine for your combo. I think the afr 185's will make more power. If I was starting from scratch, i'd choose a ported TW head because i'm partial to TFS products

Whoa now!

i am no way saying it doesn't matter, but nitrous does not require a better flowing head to produce the power of the shot you are giving it. nitrous differs from forced induction in that you are not increasing the volume of air into the cyl you are increasing the percentage of O2 into the cyl. for instance a 306 with E7 heads will still make 100hp extra on a 100 shot. a 306 with better heads will still make 100hp on a 100 shot. pick a head based on your n/a goals then add nitrous.

Look sorry to make this come up just because its a 100 shot does not mean it produces 100 hp to the wheels or even the flywheel. Every motor is different some car react to N2O differently. 5.0 mag. a while back did N2O on a Fox with 125K on the odo. Well it prioduced somewhere around 118ish if i remember correctly. As for 94-95's I have witnessed a stock 94 produce 92 hp to the wheels on a 75 shot. The heads you used will make a difference im not saying a big one but it will matter.
As for the dude doing the 306 on nitrous. Way to go! Sounds like a good combo to me. I'm sure you will have a lot of fun with it. Post pics. when its done.

Thanks again for all your help guys, I'll definetly keep you guys updated on all progress
