Was that stock heads / stock valves?
Ran a B cam in a J+P 306 with 10:1 comp, and 1.73 roller rockers on ported Eddy RPM heads. Revved like crazy and made terrific power. Would run away from a 4 valve N/A Cobra and even beat a Buick GN with big turbo and intercooler back in the day.
I believe the B needs at least 10:1 comp ratio to work as intended.
PTV clearance is a must anytime you are assembling a motor, regardless of the parts.
Expensive to find out there is no clearance thru bent valves/pushrods or worse.
Compression to make it work, absolutely.
right here kids^^^
Even more commonly overlooked, running stock / worn out springs with your new bump stick.
ya...I was surprised...
its an old 88 vert...
who knows what motor is in it...
was NOT on OEM HG in there when it came apart
yep...the stock springs on the old Foxes sucked when they were new
Barely adequate for the stock cam and rpm.
Reason I asked, normally tons of room with stock head n piston.
