302 engine compatibility question
I have to replace the 302 engine in my 70 mustang with C4 tranny. Will an 1989 302 engine bolt up to the 70 C4 tranny?

Yes a 289 will fit....As long as it is not the very early 260 type which has 1 less bolt on the bell housing.

Re: 302 engine compatibility question
yes, it will bolt up. Just remember that the 89 engine has a 50 oz imbalance and the 70 is a 28 oz imbalance. You must use the proper flexplate, you can buy an aftermarket 50 oz flexplate to fit you c4 convertor. If you must change the harmonic balancer, same rules apply and you can buy a 50 oz balancer with the correct offset for your application
