I'm a new member.
Was referred to this forium from another to see if I recognized this engine.
It is a 1928 Chevrolet engine.
I have 2 exhaust manifolds setting next to me and 4 cylinder heads in the barn.
1928 was the last year Chevrolet made a 4 cylinder before comming out with the 6 cylinder stove bolt.
You can tell the 28 because it was the only 4 they made with 2 exhaust ports.
These heads can be adapted to fit on a Model A Ford.
They are a cross flow head, that is the intake is on the drivers side and the exhaust is on the passenger side.
It takes a thick adapter plate to make them work on a ford but they do put out some horse power that way.
There are some Chevrolet guys on an other forium that are running these engines with the earley Oldsmobiel heads that have 3 exhaust ports and the same bolt pattern.
