AGREED!
BUT, try finding one in decent shape, with lower miles in certain areas of the country (maybe EVERYWHERE at this point) due to the damned swappers and drifters snatching them up before they're even on the market. (Sorry, Inflame, NOT directed at you personally. )
(It's almost as if they have some kind of 'sniper app' for this, like on ebay or something. )

I road race a E36 M3 with an LS6 swap, I highly recommend getting the oil pan baffle especially if the tracks you are visiting have left hand sweepers. Also, a large oil cooler and 15w-50 M1 oil (cheap and effective).
My LS6 is fairly stock, has home made intake and long tubes, made 365whp but the kicker is the table top torque curve peaking at 407lb-ft!

Do you have videos on YouTube? If so, I need to look you up.
What about a Moroso oil pan? I've always used one on LT1's and have never lost oil pressure in turns.

If I ditch my lexan spoiler I'm allowed an extra 15 hp. That puts me to 373. Would I need a larger cam than the ls6 to get there?
So now I'm entertaining a slightly larger cam but use stock 02 exhaust manifolds. I'm guessing that'll restrict me enough to use my spoiler. If I remove it, I can then bolt up LT's and get the power I need.
Or are stock manifolds so restrictive the adding a cam won't do anything?
I'm currently trying to figure out how effective the spoiler is at lowering lap times.

What about shorties (to save weight mostly), do they allow you to keep the Blaine Fab ducktail, or does it HAVE TO BE the stock iron deals??
Everyone on here will tell you to go with longtubes no matter what, but the above sounds like a plan.

Does NASA allow you to port/extrude hone the stock iron manifolds?

Have you done any testing with the spoiler? Consecutive laps with it and without it? That seems like a pretty steep penalty for something that could already be doing more harm than good, depending on the spoiler's design.
I would probably ditch the spoiler and take the extra power, personally.

^^^The spoiler he is using is adjustable for 'angle of attack', and he is able to lay it down for less rear downforce, or stand it more upright for more rear downforce, IF the particular course dictates that action.

Good to know. I didn't mean to insult anyone, just see a lot of spoilers and wings that have absolutely no thought or track tuning put into them. Testing and tuning and absolutely knowing that it is effective is the only way to do it.

He does NOTHING 'ricey', and is ONLY into fully functional, full (road) race parts/prep!
IF I ever come into loads of coin, I WILL ship my car clean across this country (bypassing MANY reputable road race prep shops along the way) to have him prep it for NASA American Iron/American Iron X class racing.

It looks like a freaking work of art, especially knowing it is fully functional. Thanks for the picture and the link.
All that being said, are we any closer to figuring out which engine you're getting? I know I originally said to build a 5.3L, and personally, I still would. But you have one stop shopping for the LS1, and its displacement advantage does provide extra torques, which is always welcome. I think you can talk yourself out of buying either one pretty easily, so you should probably just buy the LS1 and go for it. That way you have something to work on, and can get it going as soon as possible. Drive it, test it, and change what you need to change from there.

Seems the cost is going to be about a wash. LT's with an LS6 cam or stock manifolds with a mild cam. Then I figured if I want more power in the future, all I'd have to do is add LT's and retune it.
Your thoughts?
