wen we did a 305 to 350 swap in our 73 nova we had to swap the fly wheels b.c the one on the 350 was 2in to big..

but all your parts from the 305 will fit ur 350...cept the intake bolts MIGHT b different..oil pans ARE def not interchangeable...we tried lol

 

In 87 GM changed over to a one piece rear main seal and the valve cover bolts down the center instead of the sides and from what I know...the switched over to TBI system. So try to do all the research as you can to see if the intake will fit etc.

Does your current engine have the TBI setup? If it does then becareful with a block from before 87 do to the changes that they did. I do not know of all the changes since I have not read up on them in awhile. I hope this helps.
