Longtubes with a turbo are a bad idea. They dissipate heat faster than cast manifolds which is bad for boost.

All good info. Thanks all. But I got to fix the wiring harness under the dash too. It got fried.

the LS1 should just drop in with out the custom mounts right? stock, my truck has the 5.7 350 motor in it, which in turn is actually the same motor series for the LS1 right?

The LS1 and other LS engines are a completely different design than the GEN I and GEN II SBC motors aka 5.7 350. Parts and mounts are not interchangeable.

Ahhh. Thanks. Learn something new everyday.

STS systems don't rely so much on heat in the exhaust system. He can always wrap the pipes to hold heat in or have the headers coated inside and out.

This is true as well. I guess the fact that they are mounted so far back would make the heat issue irrelevant.

I read somewhere that there ar two types of motor mounts. One that keeps the engine at its current location but moves the transmission 1" foward and would require minor modification or the second option is that the engine would be moved back 1" back keeping the transmission in its current location. I personally like the second option since it would keep the weight more centered and should make the truck handle better.

Dirty dingo mounts are the best imo. They are adjustable and will go right into stock location
