Trickflow trackheat or performer rpm
My engine (470) was making over 500 ft pounds at 3000 rpm and over 600 at 4000 rpm.
With double the cam duration at .050 of the OP's and a track heat intake untouched with a blp 850 and annular boosters.
A 512 will have absolutely no issues with torque down low. I would not use a dual plane to make more torque and for what it's worth the trickflow 240 ports are already a high torque port ...they are small, like sbc 220 cc.
I think the 230-236 cam is going to peak around 5k in that set up so feed it as much as you can.
