Hey guys I was just wondering if anyone had any info on which heads will work with the LT1 intake conversion on my 87 IROC 350 TPI. I'm planning on doing the intake conversion and adding some aftermarket heads. I was thinking of getting some vortec's or something similar that is affordable. Also at the same time I plan on adding a cam,valve springs,and new rocker arms. Does anyone have any ideas on what head/cam combo would work well with the LT1 intake on my car. Keep in mind I'm trying to make this a budget buid up for now and get the most for my money. Any and all info as always is appreciated. Thanks in advance.

 

I think the Vortec Heads Port's would be to high To Match up nicely w/ the LT1 Intake.

however, the LT4 Intake may be a neat trick....

 

LT4 wont work either, you would have to add material to it to be able to drill the bolt holes. The LT4 has been modified to fit the fastburns though, since they have vortec and standard SBC bolt holes. But fastburns aren't really a budget head.

 

Well thats too bad, can't say myself as I don't exactly have one laying around here.

 

that's too bad..my options seem to keep getting worse and worse everyday. Superram is way too much money for what I'm trying to build right now. A miniram could be accomplished with the LT1 setup opposed to the $1000 or so for one from TPIS. I haven't seen too many other intakes for a TPI car that's moderately affordable. Anyone have any other ideas or suggestions? I've got about $2000 to play with right now as far as the heads,intake and valvetrain go. And i'd like to spend as little as possible and get the most for my money.

 

I am currently putting my LT1 intake on my Dart Iron Eagle II's and so ar the only problem I had was the coolant passages on the head were too tall and the intake would not cover all of the passage. For 65 dollars I have the local welding shop weld more aluminum in all four corners, now it covers them and then some. That is the only problem I ran into so far.

 

Holley Stealth Ram

Answer to everyones problems recently.

with 2k to spend On your Motor, I would look at exhuast, Intake and Cam, retaining the stock heads.

HSR 450, Exhuast from the engine to the bumper, 750$, cam, 200$

Puts you right in under your limit, But don't forget the computer needs...

Not to mention, You can't just slap all these parts together and expect it to run how you want, Your going to need to have some knowledge of how to tune the computer to Make them run right together.

 

Well i've got edelbrock TES headers,edelbrock catback and no cat right now for exhaust. I had alot of other parts on the car before i decided to sell it and went and sold them all(stupid me). But now that i've decided to keep it the exhaust I have on there now will suffice. I was even thinking maybe some S/R torquers to use for heads. And I also had seen the holley stealth ram mentioned. As far as a custom chip goes what would you suggest I go with to use on the car? Believe me i'm not afraid or worried about working on the car and tuning it. I plan on doing all the mods myself as I have in the past. I've gotta do the fuel pump on it tommorow..bleh that's going to be an adventure. I apprecite everyone's help and keep the suggestions coming.

 

By saying you want Vortec heads you just limited yourself. The LT1 and the Stealth Ram will not work with those heads. I have heard someone did get the LT4 intake to work with the Vortecs but took some port matching to get it right.

 

And unfortunatley the stealth ram doesent fit under a stock hood from what Ive been hearing...

 

If you alread have exhuast, your $$ ahead.

Look Into a Cam upgrade along with Some serious intake work.

The HSR may or may not fit under the hood, either way IMO that is a small price to pay

Figure, for 2g's you could pick up a nice set of heads, a good cam kit, a HSR and all the equipment you need to start burning your own PROMS

 

Yeah but would it work with a turbo!!!!

 

Well i'm not limiting myself to vortec heads only. I'm just looking for something similar that's in that price range. I'd consider the S/R torquers anything that's fairly inexpensive that performs well for the money. And if it doesn't fit under the stock hood that's not a big deal either cause I planned on adding a 4 inch cowl at some point in time and the sooner the better i suppose. I'm going to look into the Holley system and I might just go with that cause it seems like the cheapest route at this point. Much cheaper than the LT1 intake conversion or a superram or miniram setup.

 

Oh jesus... What have WE done to Unleash this ?

 

The HSR is MUCH cheaper then the LT1 intake conversion? I don't see how. Especially since you NEED to get a hood to even think about swapping. Besides the hood they HSR and the LT1 intake are competively matched in price for the intakes.
Yes, the LT1 needs custom fuel lines but so does the HSR and do they offer that? No, you must fab up something on your own.

 

The scoggin Dickey votec base makes amazing power for a ltr setup.......

TPI vortec manifold - $400

Vortec heads- $450
OR
Aluminum Fastburn Hi performance Vortec heads - $900

Cam- LT4 Hot cam or ZZ9 cam or something similiar - $200

Prom burning - $250

 

Needing to get a hood is up in the air right now. Some people say you need it others say you don't. But as I said before I was planning on putting on a 4 inch cowl eventually anyways.
