Im new to the tpi,i always had a carb.Im buying another '87 iroc and it has a 350tpi thats been bored .060over, comp cams CS XR270HR-10 Cam specs are http://www.compcams.com/Technical/Se...umber=08-422-8 was hardened in the motor by a racing garage(has all the papers)Im wondering what kind of intake/head combo would wake this baby up a little more and not be that expensive to do so??

 

Is money a factor here?

(Have) TPIS Miniram Page 17 or go to intakes(one piece intake, 8 intake bolts and a Throttle body).

(Read alot about) LT-1 Intake conversion, intakes cheap but you have to have external water lines.

(Worked on one) SuperRam, a bitch to bolt together (trying to get the upper plenum on the runners) on the car. Also there seems to be more error for vacuum leaks.

(Worked on one) Holley Stealth Ram not a bad intake, 2 piece design.

I thought at one point one of the magazines had done a comparison of the Chevy EFI intakes but I don't remember who or when.

Also AFR heads are good
Dart Pro 1's
Twisted Flo Heads

There are others but I can't think anymore

 

Money is going to be kinda tight,so id have to go cheap on this build, this car is gonna be for more show than go,but its got a decent cam so i just wanted to do more to it go get the most out of it.....

 

I think the HSR (Holley Stealth Ram) is your best money option and you can use your injectors and other items that you already have. Heads can wait for a little while the TPI is good for low end torque and the HSR miniram and others move it to midrange to upper RPM. With the stock runners and intake the engine will usually stop breating good by 5500 rpm on a 350 cid

aren't the GM vortec heads a worthwhile inexpensive upgrade on heads? i know you have to do some machine work for the intakes to fit, but for the price it may be worth it.

just some info

 

Yeah they are but you still have to buy a different intake base to mount to the votec heads, scoggins-dickey I think is the on that was producing the intake to adapt the TPI to the heads.

 

someone is making a vortec HSR, that i want REALLLLLLY bad....

 

heard too many horror stories about tpis but they do make a nice intake.

Lt1 intakes can be modified through some machining to fit on our cars. The lt1 is based off the tpis mini-ram.

Holley Stealth ram is great for engines that go to 5500 rpms.

Accel super ram is great for high hp motors and flows to 6500 rpms.

As far as the vortec heads, they make a ramjet intake for them that is really expensive, but its absolutly amazing.

 

Alright, a buddy did a build on his 86 and used the Holley stealth ram(wish i watched now haha)Now as for buying it, id buy it COMPLETE so i didnt have to deal with that **** haha.Now for the part ## i think it would be the 91404211 right??Im not sure but all i would have to do is disconnect all the original stuff,bolt this intake and stuff back on and then reconnect all of the wires right???

 

and now theyre making it

 

Not quite that easy - you'll need to get 6' of -6AN fuel line (or two 3' sections) & the associated fittings to adapt the HSR to your existing fuel/return lines. You'll also need to buy a different thermostat housing, & a few other (minor) misc. pieces. Complete details should be at StealthRam.com.

Not a really big deal to adapt to our cars, but it's not just a simple R&R process either...

 

You can buy a set of cast iron vortec completely assembled already machined for non vortec intakes for 499.99 from jegs. P#809-25534431

 

Sorry bro, thats 500$ a head. It says "assembled sold individually".

 

i knew that didnt sound right. and at that you can almost get a set of aluminum heads, if i remember correctly
