So its a 350 engine, wont see over 6000rpm. Would you guys get teh small port edelbrock heads or the big port Trickflow super 23's, mostly a street car but i love going to the traack. Or is thier some other head out there with a CARB # you guys would recomend?

antoine

i have the new afr 195 and they are smog legal.

Daniel U

That's what I want! How much were they?

scribbles

Eventually that is what I am going with, I think list is like $1400, IMHO it is stupid to go with any other head for SBC, and they are just beautiful and not much more cash. Except for all out racing, But with tpi they will outflow any TPI intake.

Daniel U

Is the Edlebrock base intake the one to get for a TPI CA smog car? I'd like to talk the wife into getting them both for the Santa Rosa motor I'm going to rebuild. It should help the AZ. S7M runners and 58mm TB. What cam should I get? That should cover all the major flow angles, right?

scribbles

Yea edelbrock is the only company still making a high-flow base, the standard head intake flows a lot better than the vetch base also. Every other brand is just a re branded edelbrock base now. Take the time to port match all the pieces it is worth it from what I have read.
----------
Also just call comp cams and give them all the specs on your car they will give you a great cam for you'r car.

Daniel U

I wonder what I should expect rwhp wise with a 5.7 though a 5 speed with the above listed mods?(58mmTB,AZ.S&M runners,port matched plunum,Edelbrock intake port matched,AFR heads,headers,exhaust,ect.) I guess I'm just
All pipe dreams for now. I have other things that are priority. My family needs will come before the IROC!

scribbles

What 5 speed you running? A stock 5 speed will never hold up, and I would think 350hp, with more torque then you can ever use. Build a sold bottom end when you rebuild it and drop a 200shot on top of it and be done with it. 95% of the cars out there will no longer be a problem, and the 200shot will kill 4.5% of the rest, the other .5% deserves the win.
----------
afr says thet there heads are like 65hp over l98 heads on a otherwise stock motor

Daniel U

I like the 5 speeds that Tremec does for the 3rd gens. They have a complete kit for our cars and should handle 500hp. As for the NOS, I want to look kinda unassuming under the hood. I know the heads will be noticable, but I will color them black.

scribbles

Stock ---------220
Afr heads ----- +55-65
Exhaust ----------+25 -30
Cam ------------+15- 25
Tune -----------+15-20

My guess, 330 - 355, if the intake can hack it. Would be over 400 with a carb but we got to work with what we have.
----------
Hide the injectors and such in a fender and under the plenum, our cars were made for hidden systems. I am off to bed see ya all tomorrow.

Daniel U

350 is better than 220. I have heard of the "Sneaky Pete" system that a friend of mine used on his TPI Vette.

scribbles

Also you are in a 3rd gen; everyone thinks we are slow anyways. Hahaha... Got my Paxton, it is quiet and I just won't raise the hood. I am going to put a 75 shot on top of that. With exhaust I am shooting for 400. Also rember you will have like 450flbs, get a good suspension and smoke them off the line.

antoine

they was 1430 shipped to my door.

Daniel U

Sweet!

its for a tbi car, and where did u find that cylinder head im curious the RHS head that is.

Kevin91Z

For a TBI car, definitely the Edelbrocks. They're cheap enough and small enough to work with the TBI intake. The Trick Flow or AFR 195's are too big for the TBI.

Daniel, for a TPI camshaft I'd get the Comp XFI268HR-113. Its the hot ticket right now for TPI systems. Unless you can live with a hairy idle, then get the XFI280HR-113. I just tuned a 350 TPI with that XFI280 cam, its loud and its nasty.

Hey Kevin. Actually i was looking around at the AFR heads and found they also offer a 180cc intake port, with a 64cc exhaust port 65cc combustion chamber all cnc ported well the intake is like half cnc tghthey say with a straight plug. So im running a 9.0to 1 comp. ratio now with 74cc heads. this will bump me up to 10.0 but with an alumnum head it'll be like its 9to1. And they have a little bit bigger port than eddy heads and have a carb # what do you think of those cylinder heads?

Kevin91Z

I wouldnt pay AFR's prices to put them on a TBI engine, that's why I suggested the Edelbrock's. But AFR's are awesome heads.

UnderCover89TBI

i found them for 1440.00 not too bad..

Daniel U

Kevin,
It will still be driven on the street as well as track, so I'm not into the "hairy idle". So the XFI268HR-113 is the one to get when I do the AFR heads and Edlebrock intake, right? Sorry to jack this thread Undercover,
Daniel U

Kevin91Z

Given Allen's success with that XFI268, I would highly recommend it for a TPI engine.

Any track time on this successful TPI?

Believe he's in the mid 12's somewhere with his TPI.
Had I not put the blower on, that's the cam I would've gone with for my TPI.

scribbles

did you go with a blower specfic cam?

OUTATIME GTA

Nope, that's probably part of my problem.

I have the very mild ZZ4. Didn't think I was going to get blown anytime soon when I decided on it.

I'll eventually look to COMP for a custom grind that the supercharger will benefit better from.

Kevin91Z

12.29 @ 112 MPH at Fontana, appx 3500 density altitude (the air sucks)

That's about an 11.76 @ 114 at a sea level track.

where I come from 3500 DA is great!
