Obviously not enough porting...

since the Mr 6 pack cam has basically stock lift (corrected for the stock ratio not really giving 1.5)I did not open up the ports, just some "pocket porting" bowl work and valve job with back cut valves to try and improve low and mid lift flow. I know that the 9.5 compression also cost some HP, but i really wanted a street driver.

Intake flow @28

.100 = 75.3
.200 = 150.6
.300 = 200.6
.400 = 229.6
.500 = 238.3
.600 = 240.4

I think some 1.6 rockers would really wake it up, but then again it should spin the tires OK now with the Super Track pack 4.10 gears and the 4 speed.

Cheers,

Arnie
