With Todd’s combo and assembly and a pull on Charlie’s Bucks dyno my 540 with -1’s made 880, I am getting close to having it ready to hit the track so we will see how it translates to real track results. Doug
i have no doubt your motor will be making great power, and given all the driveline and suspension are set for that motor, you will be pleased with the results. As i said in an earlier comment, it is just a little easier to pull 880 to 920 hp out of a bigger shortblock like a 572 or even bigger. It may require a different converter and rear gear should it be a big increase, like more than 572. I have a 580 inch combo i could run with my 572-13 heads, but it would require a gear change minimum and i am already certain my 549/572-13 motor will go faster than my 8,50 cert, plus i would need to retune it as well.
