Re: Firebird W68 - My LSX Swap thread.
Ran into issues with small stuff that I'm eventually going to address on the first page.
#1 Fuel - 97 / 98 Corvette Fuel Rails / Regulators have return lines, the downside is they're also extremely rare and hard to come by. My Intake and Rail DID come from a Corvette but it was 99 - 00 Corvette. To compensate, use the Corvette Fuel Filter which has a Regulator built into it. Some people have had luck mounting it in the inlet of the fuel rail, for some reason I was the unlucky bunch who could not get it to clear the ignition coils. To compensate it is now mounted on the fender near the brake lines. New fuel lines had to be made to complete this setup.
#2 Heater Hoses - You do NOT have to use LS1 heater hoses (Brand new they can cost around $200). The V6 ones can be adapted to work. The only part that is different is the part that comes out towards the engine after the metal tubes and thats because LS1's are longer engines.
Just cut the portion after the tube and then fit an adapter to run extended hoses to the radiator, much cheaper.
#3 A/C - The A/C lines between the V6 and V8 are different. It appears though that you may still be able to use the V6 lines as long as you use the V8 pressure switch, but I'm still not 100% certain on this yet.

Other issues we've been dealing with:
Building the PCV system
and
I just found out I bought the wrong radiator (from a manual car, stupid mistake) I'm either going to buy a transmission cooler or reuse my V6 radiator, haven't decided which yet.
