i got a the car a year ago it has a 305 TBI
when i got the the guy had told me he had rebuild it but im not sure.
i was thinking it would be best to put a brand new motor instead of rebuilding it again and i would like some feedback on what kind would be best without having to replace alot of parts.
i know the transmission would have to for sure

would this be an alright engine? or should i go with something beefier?
im not into racing i just want it to run nice

Great looking car. Brings back memories. I think most guys will tell you that pre-85 engine with 2 piece seal is leak prone. I can't understand from your post whether your current engine runs fine, bad or not at all. If the rebuild was a quality one, and its running great now, leave it be. You have the reliable TPI setup that should be troublefree for a long time to come, unlike my orig car. By the way great looking car. Is that the orig paint?

the car runs fine, but not like a 305 should be running. yes original paint. and it doesnt have a tpi it has a tbi

If it's an '85, it didn't come from the factory with TBI.

It either came with TPI, or a carburetor.

someone rebuilt it and put a tbi on it.
