From what I've seen, the heads, and intake, have more effect on the rpm of peak TQ, and HP, than cam shaft.
If your heads are as good as Ricks, you'll need to rev it past 7500 rpm with a cam that has 276* duration.
Rick's needs shifted around 7400-7500 rpm now, with 260* duration.

I think over converter, and under cam, if the lowest ET possible is the goal.

If street driving is part of the equation, there will be compromises.

Hiya , i dynoed the engine the other day , its a little bit different in build to originally planned . It has 12/1 comp and we dynoed with 109 fuel. Imageit repeated easily and we did start to have fuel metering issues above 7k and we ran out of time and Money for chasing. It had a custom carb built by ray je .It had 17/8 pipes . cam by comp cams . It should be a good ride . ;-)
