Engine swap

Asked by Feb 03, 2017 at 04:54 AM about the 1988 Chevrolet Caprice Classic Sedan RWD

Question type: Maintenance & Repair

Hey guys
I have an 1988 Chevy caprice with a
standard 305 in it. I have a 2 part question.
1.) If I swap my engine to a 5.3/ 5.7/ or 6.0
do I have to swap my transmission also.
2.) what would be the best cost efficient
truck to swap engines from that would
drop right in or that would drop in with
minor work on my 88 caprice.

It will fit and tes you need the tranny, the most cost method is swapping with the same engine...

I want more power than the 305 thinking a 6.0

I think you would have grief dropping in a 6.0L engine.

I would swap in an engine/tranny combo, but be forewarned length of driveline will likely change so your current driveshaft will not work, and if you increase weight significantly you'll have to bump up brakes and springs. 305 and 350's share the same block, so no significant changes there, can even use same engine mounts.
