okay I need a screaming build up for a 2.3 but everything has to be stock can bore, oversize valves, no chevy 5.7 rods no porting polishing.

the combo I've come up withso far is

75 pinto head with a merkur short block(merkur had a longer stroke than a regular 2.3 or that is what i'm told) with flat top pistons running a 500 cfm holley 2 barell any other suggestions
this is for a race car!
