Thanks Brent,

I see the flow numbers on the intakes are POST Tear-down for his EM 285CC heads, which are lower than his as new bench set in the magazine.

The Chapman 285s from Steves bench (Mopar Muscle May 2004 Issue) were:

.100---77
.200---151
.300---220
.400---283
.500---330
.600---364
.700---375

Dwayne (Fast68Plymouth) flowed my actual set of 285s for Moparts and they were pretty close to this, If I remember right (at the time ) he only used a 10" flowbench so the bigger (>.600 lifts) were maybe a little low compared to being measured on a 28". Here they are from the tech archives:


Lift" I/E

.100 72.5/58.2
.200 153.7/118.6
.300 224.3/178.2
.400 285.2/218.2
.500 329.6/232.8
.600 361.9/245.1
.650 368.1/249.9
.700 364/253.1
.750 364/254.7
.800 364/256.3

At the time we were commenting that although they flowed very close to a well ported set of -1's, they do so with a far smaller CC intake port, so they acheive the flows with much higher velocity (which for a street car equates to responsivenness and torque)
