Here's another view of the roller rocker arm cylinder head I'm working on. It will have oversize intake valves and oversize stainless steel exhausts for a small block V8. That engine will also have H beam connecting rods, aluminum pistons, a roller cam, and main bearings for a Chevy small block 400 V8- - - -1948-53 216 main bearings are almost impossible to find, and cost over $200.00 a set when they're available. SBC 400 mains are usually less than $50.00. That conversion requires some pretty serious whittling on the block and the crankshaft- - - -it's not a drop-in fit!
