Just Asking,,,Is the intake ported? The torque is insane so I think as long as it hooks it will ET very strong and just shift it fairly low and keep in that sweet spot. The intake should outflow the heads ( or to say it better, easily keep up with the heads) and if it doesn't you're leaving some top end on the table. When Larry Smith ported my 337 single plane for my Chapman Max Wedge heads.... it made a much bigger difference through the entire power curve than I even anticipated, it gained peak torque RPM and HP that cost little to nothing below the curve. Any time I see a wedge that torque peaks at around 4500 might seem to be slightly under ported, but the torque you have is very stout for 529 cubes.

So is the cam degreed at 108? that should be about right for that combo I would think but I tend to agree that strokers tend to like a big lobe that's in early because the piston swings back toward TDC quicker (gives up more displacement per degree of crank angle) ...so (at least in theory) you gotta rely more on the intake charge than say a shorter stroke/longer rod combo of the same displacement. I haven't built many strokers on 112 centerlines and of course the headers are less than ideally sized for anything much over 5200-5400 on a motor that big. That definitely is limiting your top end in that your HP will fall off quicker after peak torque compared to a 2" tube.

Is that a B or RB deck height? Just curious. I'd love to have a 4.500" bore to work with one day!

i agree though, the only dyno that matters it the timeslip, should be a great bracket motr that lives a good long time!! Congrats!
