    So the only thing that needed to be done to the coolant hard lines was to bend the nipple out a little bit??

    I wanted to ask if anybody has done a swap like this, but using the LS2 90mm intake and DBW TB from an 05+ vette?

    Also since you have to swap the water pump, and grind the alt bracket for clearance, has anybody ever thought about swithcing the truck accessory brackets over to a vette or f-body setup?

    I mean it would need a bracket to relocate the tensioner, just use a vette or f-body one. Althought i dont think youd pick up any power by switching to a different accessory drive.

    I have a complete f-body front drive setup with the ASP underdrive crank and alt pulleys and a new water pump. and the alt and p/s brackets and a/c comppressor brackets and was thinking about swapping them out and doing an LS2 intake swap at the same time i do a cam swap, but since the f-body has the alt on the lower drivers side im not sure if it will clear the rack or not.

    probably not worth it in the end, but just thought i would ask.
