I have no problem with either motor.Its your individual decision. I have even played w/ ideas of a ford 302 in my Volvo! Had one in my Austin Healey.As long as you enjoy the car/hobby! And also , this site is not as "chip on their shoulder" as it may have looked ! As long as the car runs I think its good , esp. if it looks good and/or old. Would`nt mind an old Volvo 544 w/ a V8 for inst. , but I love a correct car too! Just siold our military Volvo Tp21 (VERY rare, 724 made) that we had a chevy 350 in!Also added a/c etc. Just have fun!!!
