Jay, Brent ,
here are the flow numbers on the heads,
Intake flow Exhaust flow
.300 - 216cfm .300 - 160cfm
.400 - 267cfm .400 - 197cfm
.500 - 309cfm .500 - 231
.600 - 338cfm .600 - 262
.700 - 361cfm .700 - 279
.800 - 379cfm .800 - 288
.900 - 390cfm .900 - 292
1. - 399cfm 1. - 293
Intake flowed with clay orifice, Exhaust flowed with no pipe. these heads had been hand ported a couple times in the past as i have had them a very long time so there were a few very small places that the CNC didn't hit which probably plays into the numbers.
Jay, i maybe shouldn't have set an RPM limit as of yet, im open to spinning it more or less. id like to get the most power+torque out of the combination and maybe let that dictate my shift and max rpm. i think my biggest handicap is the factory block. its a good block with decently thick cylinder walls even after a .090 bore, its filled to within 1-1/2" of the deck, has the re enforced webbing, im using pro-gram cross-bolt caps and a concept design main girdle. i will be using my own priority main oiling setup as well. pistons are venola custom , rods are manely aluminum (shelf), crank is a scat steel. my bob weight comes in at 1904 grams. anything else i can help with ill be happy to. i plan on documenting the build here very soon once i start putting it together. that is as long as i don't get to many laughs, LOL..
thanks so much guys for any help you may give. also i have a cam here but id rather wait and see what you guys think before i reveal what it is because the few people i have talked to (mostly the so called cam techs) once i tell them what i have i always get the "oh that should work" and yeah idk id rather know what you guys think.
thanks again for any and all help.
not sure yet on the pond block CID, more piston, more stroke and more throw lol. to be determined .. one step at a time for pore boy racing..
