Wrencher,, thanks for the reply, we appreciate it. My son was hoping for more hp, but its basically just a really high dollar slightly over stock engine. Should run good though.

the machine shop is real concerned on pinging here in PHx. It gets really HOT here in the summers. Plus, we don't want to have to run premium if we can help it.

I"ll be getting my 350 going as soon as the 400 is done. Would you mind running my numbers for me? If you can, thanks.

stock stroke and rods
Speedpro coated hypers, 9.0 cr
Quinch set @.045 ( hopefully)

Heads are cast chevy '882, '76cc 1.94, 1.5 stainless
runner cc unknown

Crane cam, hyd ( non-roller)
216@.05 both lobes
adv dur. 272
seperation 110
gross lift .454
Crane full roller rockers

Edelbrock performer intake and 750 q-jet
stock HEI with Crane coil
350 auto, 3.41 gears. ( yuk!!)
