Which route to take...

I currently have a 1985 Iroc Camaro. I have in my posession an LT1 and 4L60e. I really want to choose a different route. I was going to go twin turbo which is why I had the cast iron block but I really think I want to keep it N/A (If possible). I want 500hp to the wheels while still being semi reliable. Of coarse an ls7 is the engine I want but I have heard that it is extremely expensive and for 1/2 the price I could build an LS2 or LS3 that would make more power than the LS7. Any suggestions??? I can find LS2's all day. LS3's are a little more rare. Could I get simular performance out of an LS1?? Keep the LT1 that I already have? I do not want to keep the vehicle automatic.. I want t56 or the t6060. I am open to all suggestions ... Build will start November 1st

I would keep the LT1 make it a 355 stroker. 200 CC advanced induction heads and a decent cam will give you 500 HP relatively easily.

355 is not a stroker, its bored 0.030 with the stock stroke. You're looking at almost 600hp at the crank to get 500hp at the rear wheels. That's a serious build for an LT1. I'm not completely sure but I think you have to be careful with how much you bore an LT1. There's not a lot of meat in the block before it gets weak. You may wanna look into that before you start your build. You're gonna have a small fortune in the suspension just to get that car to hook up with that much power.

You can do a 355 stroker. There is plenty of meat in an LT1 to do a .030 overbore. Also 600 crank 500whp is pretty easy with an lt1. It's been done my many many people.

I'd go 383 or 396 with the LT1 if you're trying to get 500 rwhp. It would be the easiest way to get to that number with all the California emission bullshit. Unless you know away around it. Also, are you against using nitrous? Nitrous is the cheapest, easiest, way to get to that number without a bunch of emission concerns.

If you're doing it by the book law wise in Cali, no long tube headers, you have to use cats and a cam that won't fail an emission test. You face these issues no matter the power plant. But you're a cop right? So maybe you know someway around it?

Besides nitrous, the only other Cali legal power adders that I've found for the LT1 are STS rear mounted turbo systems and Procharger P-1SC .

I'd go 383 CID, ported intake manifold, stage 3 ported and polished heads from Elliott's porting works, or maybe even aftermarket heads (trick flows, AFR) and deal with two cams, a really hot cam to make the power you want, and a milder one (maybe the stock one you got) to past emissions. Just my thoughts.

Just my thoughts.

From what I have gathered form you guys is since I already have the LT1 I should just keep it... 383 stroker is a route i'd be able to take. I am not afraid of N20 at all. I just wasnt sure if N/A lt1 could make 500hp to the wheels. With what you are telling me is it can.... I had origionally thought about going with the sts kit because it was CA legal (though thats not that big of a deal) and that still may be a route in the future... 383 sounds like a good idea.... the money I'd use to buy a new engine can be put into the LT1 to make it work... I'll take my 4l60e engine and transmission off of craigslist then lol..... I still want to upgrade the 4l60e to t56.. I guess the extra funds will go to that. thank you guys very much. 2 months then the build starts!!!!!! I'm excited.

I've never heard of 355.. why would someone go that route rather than 383?

If you don't want to buy a new crankshaft you can reuse the stock 350 crankshaft. you can make big power with a 355 and 383. but with the emission limitation, I figure you can make more hp without using a super non emission legal cam in a 383

edit: But a lot comes down to the quality of the tune too, as far as power, and emissions.

8k in a v8? omg... My evo revved to 8200 but it was a high strung 4 banger lol... thats some crazy stuff. I see the 383 stroker kids all day on ebay. I've heard you should stay away from certain brands. off hand can you name any? If not I'll put in the leg work for research if i have to lol.

Oh yeah 8k is no joke in a V8... Proof of such shit, I've seen this car run in person http://youtu.be/Ceuu_QM-vGU

I would avoid any off brand kit. For a N/A motor eagle kits are plenty good. You will want to use head studs and stud the mains at the very least. You may think about having the block splayed to 4bolt mains.

No problem. That car is actually the single biggest inspiration for my car as that camaro now sports a 383 with a PT88 and make just over 1k HP with a failing clutch.

Oh wow.. nice.. thanks for the info... I found many Eagle.. good to hear they are good enough. Thats the route I was thinking about going. I've heard about having a block splayed to 4 bolt mains.. I just have absolutely no clue what that means.. I'm sure a quick search on here would give me plenty of information. I'm kinda new to the american scene... I've had the car for almost a year and a half and I havnt really worked on it yet.. but Come november....

A 2 bolt main splayed to 4bolt is actually stronger than a block cast as a 4bolt. It involves trilling and tapping the block to accept splayed main caps. I had it done to my 383 and it added about $500 to my machine shop bill but worth every bit of it.

Sounds like a worth wild upgrade.. 500 dollars for xtra safety and reliability doesnt seem like a bad idea...

Wow 94 T/A that Camaro you posted was insane! And now you say it had double that power at this point? Any videos of that? Or is the failing clutch got that on hold?

Here's the last video he's posted of it. http://youtu.be/4DGmnrbyaVg

I saw it in person last year at the LTx shoot out. He had traction issues and still ran high 8s
