Match this 500hp/500lb-ft Combo?
Last week there was a 434” Pontiac on the dyno here.
400 block with a 4” crank.
Cnc ported Kauffman D port heads(2.11” intake valve, 290cfm) RPM intake, Holley 750, 1-3/4” headers.......230/236-110 HR cam.
554tq/500hp
Lots of lines on the sheet in the 490’s.
The VE barely touched 100%, and at the point of peak HP(5800) it was down to 91%.
The power curve hung on better up top than I expected considering the short cam timing.
The heads are working pretty well.
