I have a 408W
AFR 185 Heads
12.8:1 Compression
Hydraulic roller 244/250 @50 600/600 lift
Has been a best of 6.51 in the 1/8th. Everyone says the heads are way too small and if I were to swap to a set of AFR 205's it would pick up a bunch.
Just curious how much do you think it will pick up.

Head swap like that my also need a converter stall change but might be worth up to .2/10s

Trap RPM is a valid parameter. Have to be spinning it fast enough to utilize the increased port volume / velocity.

AFR's are slow, put something fast on it like a Brodix.

<<< Out of the box, Brodix are the fastest on the planet, conventional 23 degree sbc anyway.

Everyone knows by now surely, AFR's you'll need a baby blower and a light car to keep up with a out of the box Brodix T1 233.
