I have just recently hauled my 85 442 from my folks house to mine to restore it. Well, I rebuilt the 307 "9" about four years ago and had to leave the car behind because of military reasons. I pulled the engine out and it looks really good, but some of the gaskets are leaking. My Question is. Is it worth replacing the 307 with a 350 Chevy and will it bolt up?

 

A 350 chevy will not bolt to your mounts. You would have to change frame and engine mounts. If you have a dual pattern bolt pattern 200-4R it will bolt up to a chevy. I would suggest finding an Olds 350 or 403 which make really good power and will bolt right up and keep your 442 all Oldsmobile. I would do the 403 with 72 or earlier heads to up the compression and nobody can tell the difference between it and the 307 until they try to race you!

 

Thanks for the advise Orange442, That makes perfect since now that I think about it. I will do my searching for my new powerplant.
