This is a tough one......... Being we do not have a bunch of specs on the car, converotr, gearing, tire, cam specs.

My guess is the motor is out of wave tune for the set-up he was running with the other top end.

The Runner Length, Port Volumn, Velocity, Cam timing Etc. needs a different Set-up.....

Lem , you saying the flow velocity is the same for both heads ? lthat would be great .lol ADD: I didn't say needs new cam , headers can be mod . longer/shorter (if able to)

Please notice the Laughing

thing. I do think the A460 heads would like a different cam than the BT in most cases .

Not a car.......it's a hydro drag boat with 2 speed Lenco and voomies.

Motors not making the same torque in the same range as the previous top end = reduced ET.

Different Gear Ratios or Prop needed?
