I have a 69 mustang grende. I had to strip it down(pulling engine and trans, rad,etc.). I am done with the suspension and brakes and someone gave me a 390 with trans. The car came with a blown 302. The qusetions I have are:
Do I need to beef up the suspension?
Do I need to change the motor mounts?
Do I have to move the Trans cross member?
Do I need special headers??
I know that this will be a pain to change over but I am up for the challenge. Any advise for this would be helpful
Thanks
