If you just matched the specs from the sbc in a mopar, would you get the same results?
230/236 @.050 duration cam
260cfm int heads
10:4:1 CR
Same intake,
Same carb cfm
The big question I have is: does the exhaust flow on the sbc make a big impact on its breathing? BP has it out flowing the RPMs more than I think could be easily ported, especially at low lifts.
CFM Port Flow Average @ 28"
Lift. - BP. - rpm (Hughes)
.100" - 112 - 55
.200" - 155 - 113
.300" - 186 - 150
.400" - 203 - 176
.500" - 208 - 189
.600" - 216 - 196
Hughes max effort cnc on the exhaust port doesn't even catch up
