Yes, and well.
Chevy didn't make a 306. A 302, 305, and 307, all of which will work just fine.
the block & heads are the same you just have to pull the 305 out & put the 350 back in
In the cylinder heads.
take them to a machine shop
1976
Yes they will, but 305 heads have a smaller combustion chamber so it may raise your compression ratio.
Yes, they should fit ok. 305 heads should bump up the compression a little.
Oldsmobile used to make a 307 V8, but it has nothing in common with a Chevy V8.
The headers for a 350 and 305 are the same.
Is a 2.8 liter engine a 305?
The Chevy small block V8 305 cubic inch engine was manufactured between 1976 and 1996. It was used in cars and trucks.
It depends on what heads and ignition system you're using. You'll have better luck with AC plugs in a Chevy.
