I have a 91 RS with TBI 305 I decided to go to a 350 and I was wondering if everything will bolt right up to my 1970 350 block. I want to put everything on there just like the 305 the only thing different will be the heads. Will it all work?

The 91 engine has a one piece rear main seal and you will need a replacement flexplate/flywheel. The intake bolts in the center of the intake are at a different angle, you may be able to make them work if you enlarge them and there may be exhaust manifold bolt up problems, most of the late model heads have 7 exhaust manifold bolt holes and the older ones only have 6. Hope this helps.
