I can get a really good deal on a sytemax intake. My main concern will it help or hinder my current combo? All thoughts welcome. BTW I was also thinking of stepping up in t-body size but am still undecided. Will the upgrade in intake and t-body give me any gains? Or is this intake to big for my current set up?

Mods: Afr165s, FTI cam, street heat intake, 65mm tb, 80mm p-mas, 30#s, 373s, t5 and every other possible bolt ons.

Ask ED what he thinks if the cam will work with it.

My guess is he'll say no. You have a heavy car with no way near enough gear.

A 75 tb will work good and you need more gear! Whats the rpm band on the cam?

When I had the cam ground by Ed I mentioned to him that I was willing to move up to the track heat upper and bigger t-body at that time. He said to drive it this way for now and that we could always swap to a holley later if I felt I wanted more. The cam is for 2000-6200. I tried to e-mail him but havent heard back. I just wanted a little feed back cause at the price I can get it for Its not going to last long.

Don't forget to check hood clearances.

4.30 gears wouldn't be out of the question if you went to the Holley intake. To get the most out of it, you'll need some more RPM at those cubes. This may also necessitate some valve train work, but Ed can definately take care of that.

Nice job going with the 30# injectors!

The heads are already upgraded w/ the ps3 springs and matching hardware. 4.30's seems pretty steep? Will it actually kill that much low end?

I agree with asking Ed, he will know - give him your cam specs. I also agree that the cam/intake will not be matched as good or ideal, unless Ed 'sets' it up like that.

Now, a 75mm throttle body will not give you any gains worth the price, more than likely no gains at all.

You have plenty of gear, a friend of mine had 3.55's and a Systemax on a stock engine, pulled great actually:nice: Ran strong...

Gear is a band-aid for lack of horsepower...keep your 3.73's if you like money/gain benefits.

30lb injectors are too big for what you have. I have them and I know. 24's would be great with no tune, if you can get a tune get 30's.

4.30's is pretty ridiculous unless you have a 'weekend warrior' or strip car. Watch out for bias post.

Anyways, buy the intake while the price is hot - if you think (Ed thinks) it would be good, then use it - if not, sell it:nice:

5spdgt.... I have an sct 4bank chip from Don at lasota racing along with the wideband set up to help him dial in the tune. I got the 30s for basically nothing when i bought the heads. You say your friend ran the systemax on a stock motor and it pulled good? What type of heads was he running?

Yeah, like I said, if you can get the tune (which you shown you can/have) then the 30's are fine:nice:

My friend was using a stock engine with stock heads, cam. It was just the intake and some bolt-ons. It ran just fine. I wouldn't say it was ideal, but with a custom cam matched with the bigger intake and AFR heads, it would be even better.

His car pulled strong, he was running around the 13.7 range at 99-100 mph in a 94 vert. He had throttle body, maf, full exhaust, roller rockers, timing was bumped. It was also with 3.55's. He used to be on this site but he has been 'inactivate' for a few years, he called me a few months back but I haven't talked to him since.

What I'm getting at is buy the intake if it is a good deal and if Ed thinks it will be fine, go for it:) If not, sell the intake and hope you get your money back or more...

LOL, no they aren't. Hmm, I make a LOT more power than your 306 last I checked. Its called gearing the car for the powerband ;)

Adam (blackgts) as usual hit the nail on the head. He knows his stuff! :nice:

Wheres daggar, I have to ask him something :)

Your car is slow. 380 (or so) rwhp is nothing. Just because all I can afford, and more so, what I want to spend is on a rebuilt 302 that is my choice. It does not reflect knowledge or 'need for speed.'

What do you run in the 1/8th mile by the way? Mph??

His powerband (from the cam) show that 3.73's are fine. His 'powerband' cam specs are what mine are for 3.73's. Ed knew I had 3.73's and I told him I wasn't changing them. I didn't gear my car for point A to point B, it is geared to get there quicker with a lesser gear and for nice driving in town and highway. My parts are all very well thought out.

So again, I have no idea what the whole 'my car has more power than you do' clause came from...I guess that is what one stanger says to another when there intelligence is tested.

The money/gain benefits, is that he can spend his money better on something else...

Your bias, as your CT suggest;)

Incorrect (go figure) I was going through through the traps at 5500 with my 302 with 373's at like 109 mph. I was under geared and his cam looks to be hotter. Ed told me a 410 swap was a good idea back then. Instead I build a new engine.

The my car makes more power comment was to counteract your redundant comment about gears being a band aid to lack of hp. My car is slow, never said it was fast. What does that make yours then?

I did not put that CT there. I guess youre biased too, "5.0 owns all" huh?

Count down to extinction.....

Yeah, I admit it, I'm bias...that goes towards me liking the 4.6's - surely you know the story behind that one.

I know you didn't put the CT there, you can't, your not an admin/mod.

What I was saying about Ed was I told him I had 3.73's and wasn't going to change and his 'cam powerband' on my cam sheet is quite similar to his.

It makes mine slower. I have never bragged about it being fast. I'm in blown zo6's, kb DOHC cars, h/c ls1 with 150 shots on a decent basis. Used to be anyways, to busy now a days, dang factory:bang:

Anyways, if you would like to discuss it further you can take it to the PM's. I will not post anymore offtopic info to you in this thread. Thanks...

Well just got an e-mail from Ed. He said to grab it and throw it on cause its about the best piece out there. So along with the new intake im going to get the 70mm t-body. If anyone is interested i will be selleing my whole TFS w/ 65mm tbody.

I typed 4 different responses to this, but in the interest of civility, I will just say that this statement is flat out wrong.

I already explained what the statement I said made. He won't 'need' the gears. Friend did fine with stock engine 3.55's and the Systemax. If he was building the car just for the strip he can match it to him rpm needs. 4.30's are not what he 'needs', he may 'need' 4.10's, he may need 3.90's, it just all depends where he shifts, where he traps at, tire size, tranny type, power, etc. That is if he is going just for the strip. 'Gearing for the powerband' is for strip cars. I didn't gear my car for the powerband and I'm happy as a penguin:)

95opal - Get that intake:nice:

5spdgt.... Im getting ready to go get it now. Just making a list of the other things im getting to go with it. 70mm t-body, polished elbow and some gaskets. Thanks for the help.

If youre going to change tb's, get a 75mm. Thats what the opening of the holley is, so use that.

Like myself and blackgts stated, you WILL need more gear to take advantage of what the holley has to offer.
