GM Aluminum Block Small Block Chevy Casting 0 359198

[SuperNovaSS]

I should have tried to measure a bore when the pan was off. The valves are GM units which is the reason a took a picture of them. It looks like the engine was mounted using the studs coming out the front of the block.

The blower that I put on the engine on the last couple pictures is mounted to an original GM dual quad intake and the ports don’t come close to matching up. The ports on the heads are much higher.

Thanks,

Jason
