ok I know it's been asked before but everyone seems dead set on using a 408 in that thread. and I just want to know what I would need to swap an ls3 into a Fbody with a T56 tranny. . .

Will the ls3 bolt up to the tranny or do I need an adapter plate?
what oil pan will I need?
and what else am I missing that I will need?


thanks.

why not an ls7? i think the ls3 is a little different platform

it will bolt into your car...... but you will need adapters harnesses, and you will need to pull the crankshaft out and replace the 58x tooth reluctor wheel with a 24x tooth reluctor wheel otherwise the computer will not recognize the crank signal

price for the ls7 is 13k for a crate engine. ls3 is 6500. . . pretty sure comes with ecm. . .but waiting on a replay from the company that has them. the ls7 is going to be pushing only 25 more horses then the ls3. at least the one I'm looking at that comes from gmpp with a warranty.

its the same as swapping a 2006 or newer ls2 in. search it. you'll find 2 million posts on it.

i thought the ls9 and ls3 were based on the same and the ls7 and ls2 were based the same way?
