I was wondering if anybody has sucsessfully swaped a sbc 350 in place of an olds 307 in a 85 cutlass. My 307 runs fine for 4 or 5 mins or so, with blown head gasget and all. I have a 86 chevy 350 4 bolt main complete with accessories sitting in my garage. I know i Will have to re-run my gas lines, and i will need new frame and motor mounts. DOES anyone know where i can get these mounts from, or what i am looking for? My tranny will bolt up to the shivey i was told at the trans shop. is there anything else i need?
