automatic 6 to 8 convert.

this may be A stupid guestion. but I am going to ask it any ways.


I know when you have A manual trans and going from A 6cyl to an 8 you need to change the trans and rear end. but what if you have an automatic trans and going from A 6cyl to an 8cyl.


and since I am posting I will ask another question instead of posting again. my brother in law has A 64 mustang with A blown 260. and he would like to know if he could just drop A 302 in untill he gets anough money to rebuild the 260.(he allready has the 302) I told him no cuz I think the 260 has A 5 bolt bellhousing and the 302 has A 6 bolt bellhouseing. but I am not sure.so can it be done.



thanks

you can use the stock 6 cyl rear with a V8/auto combo as long as the V8 is relatively stock, and you dont use slicks, or otherwise stickey tires. best though to use an 8" rear and leave the six cyl rears to those of us who want to keep out six's and spank the V8's

you are right about the 302 swap in place of a 260. if he uses a tranny from the 302 then it is a bolt in swap. otherwise no.

well if I have to change the trans I might as well change the rear end as well


and thanks for confirming my apinion and the 302.
