Match this 500hp/500lb-ft Combo?

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

The flow data from Ede is that the Magnum RPM’s flow 251/[email protected], and 260/[email protected].

The cam BP uses with those heads on their 408 is already 5-6* longer than the 230/236 cam in the SBC.

As for the ex flow....... you’re comparing data from two different sources........ which in my mind makes it not comparable.

I just prepped & blended a set of LA RPM heads. They flowed 260/[email protected] lift on my bench.

There is no doubt in my mind I could make over 500/500 with them.
But...... it wouldn’t happen with a 230/236 HR cam.
