LS1/LQ4 Turbo questions/ exhaust headers?

[SShep71]

What is everyone using for their turbo exhaust manifold setup? Im thinking about switching to a dual turbo A/R 60 M24 L Garrett intercooled LQ4 in my 69GTO I have a good engine picked out but have a few questions. I am not looking for a super crazy motor 500-600 FWHP. I am going to port the heads that came on the engine (yes I know what im doing) and have a good valve job done. Here are a few of the questions I have for the gurus out there. I will be pairing this up to a 4L80E

I found a complete engine from an 04 2500 silverado with 70,000 on the ODM. Will the bottom end hold up to 8lbs of boost without many problems.

what are the suggestions for exhaust headers?



What are the suggestions for a cam? I want a good streetable cam with a mean rough idle

What suggestions can you make for a good intake

What are other suggested parts I should replace or upgrade?

thanks guys
