Yes, and well.
Chevy didn't make a 306. A 302, 305, and 307, all of which will work just fine.
take them to a machine shop
In the cylinder heads.
the block & heads are the same you just have to pull the 305 out & put the 350 back in
Yes they will, but 305 heads have a smaller combustion chamber so it may raise your compression ratio.
1976
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.
Yes they will fit , But you will notice no change what soever. ( no more power )
