Re: 1970 Kiekhaefer 427 engine help
GM Built a tall deck 427 "Truck" block in the 70s that was 1/4 inch taller because the pistons had a 4th oil control ring installed for less oil consumption this engine should have a gear driven cam from the factory. Mercruiser used this engine for thier 325-350 HP inboards. Engine shops found this block useful to create some of the early stroker engines
I had one 961 block lying around few years ago and after checking into it I decided I need at least more wall thickness to feel safe. 4.251+125= 4.46, a 502 is 4.466 (+060 over) so I thought a 502 with a stroker crank does it for me plus I have then additional overbore chances.
