Based on the TF 240 CSA measurements that were posted HERE, I'd say it's going to be RPM-limited comparable to a non-MW Stage VI port.

Where did you see the peaks for the bracket Stage VI combos you built in the past? I know my "less serious" stock-stroke build was 6300-6400 for HP and 5000-5200 for torque.


Yes Mick on here ran a 3.75" 440 in his Dart with 12.7CR, MCH Eddy's@320cfm, (very similar to 240's), Victor intake and a 1050 but ran a puny DC.590 sft, that got shifted at 6350 or would slow and was going flat at 6750 through the traps, he had the chance at my old .650" Comp sft cam for no money which would've woke it up a bit but didn't bother, couldn't persuade him, shame, might've got it in the 9's on motor I reckon, only needed a 1/10th and a bit. No cars with 240's on them here that I've seen, I think were a bit behind the times and slow to catch up to quality head use on the 440>493 size motors.
