Thread: swap to a non sc engine?

i have a gtp and blew the motor a ouple weeks ago. i was wondering what i would have to do(and if its a good idea) to swap in a 3800 out of a gp gt. i want to do it because of the higher compression. i also have a 3.4 pulley, xp cam, heads up are ported, 3in dp. would it be too much stress? and i heard the non sc 3800 have the timing advanced 1 degree stock? what do i do about that?

Lemme guess, you blew the front bank of pistons?

well you'd need the heads up assembly with a few other parts, see the top swap thread and get headers.

no. i spun a rod bearing, cam bearing slide out halfway and got all chewed up, and the main bearings are washed out. i have a l67 motor. i wanted to bottom swap it for the higher compression.

done.

yeah thats the only thing i was worried about, blowin it up. im at almost 10lbs of boost now with a 3.4 pulley so.

Get headers and make sure its not knocking.
