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?
