i have a 1969 caprice and a ls1 5.3 off '07 chevy complete with harness, 4l60e and computer. i want to mate these two but i have never done a swap before. has anybody done/heard of an ls1 into these caprice/impalas? i have an electronic throttle body, i can exchange that to the cable ones correct? i swapped out the oil pan to one from 98-02 camaro. i also want to change out intake, can i use oem injectors off the 5.3 truck? how about motor mounts, is there kits out there that i can purchase that will fit the ls1 to b-body? alternator, starter, injectors, oil-pressure, water temp...is the m.a.f needed to start 5.3? any help is aprreciated...

 

My friend and I discussed this exact swap yesterday, as we have quite a bit in the last week. My buddy has a 4dr 68 caprice coupe and were thinkin; cheap adapter plates, f- body longtubes, 95 caprice fuel tank, trans x-member, maybe rear end (if it fits) ecm flash, rework the truck harness and...

 

im assuming adapter plates that are commenly sold on ebay? rear end, x-member and fuel tank all off a 95 caprice/impala??

 

Absolutely, e-bay adapter plates. 1991-96 Caprice or Impala fuel tank and crossmember should need very little to no fab work, not sure on the rear end. Should be fairly straight forward, i think. My swap car is a 79 Cadillac Coupe Deville and my plans are the same, hope to be starting soon.
