Texasmidget, the piston I couldnt see in TKs performanceforums post
but apparently he had the pics on aussiev8 forums.
Yet it is the usual Nascar combustion chamber design that is used on
everything these days prob originated from Larry Widmer or one of those
great Nascar engine builders. It seems to be the most popular chamber
design on all V8 engines and circletrack L4 both cross and non crossflow
pushrod heads. I guess with bigger bores on an A series such a small
chamber if using the A12 head would be fine with flat top pistons if
the cam is not too crazy where valve reliefs would be needed.
