Re: A460 BBF Head Flow

Some more flow numbers for you junkies.

Full CNC Ported (C. Evans) New Style TFS A460's average of all 8 ports.

28" H2O, No Exhaust Pipe, on a 4.625 bore, 2.35 Rev SS Intake, 1.88 Ferrea SS Exhaust, Flowed on a SF600 Bench

Intakes / Exhaust

.100 74 / 58
.200 161 / 118
.300 245 / 165
.400 315 / 200
.500 375 / 235
.600 408 / 267
.700 439 / 294
.750 451 / 303
.800 465 / 312

The exhaust flows are low due to a couple of ridges and I'll post the revised flows later.
