Dave,
What were the grind numbers of both your cams?
I've got a new stroker in the works
the big cam was ur 258/262, Lift .639/645 w/ 1.5's
the small cam was a comp XR280R
they both made the same torque, no matter what intake, head, or anything else we threw at it - although the RPM range changed significantly.

Looks like an article full of helpful info. Out of curiosity, did you consider using Mopar's small block casting? It has siamese bores and can easily deliver 440 cubes without too much hassle.
Was cost the main factor? I know the block ain't cheap but you might have made up for it by saving on machining expense.
Yes I considered it Jon - I had the X block sitting here collecting dust.

Loooking back on the build, I'm thinking about doing something very similar and just trying out the Airwolfs. I have a 360 block but might try to find a 4.22" max bore Siamese if the right deal comes along. torque is definately more short block configuration, displacement and then compression related, peak torque is your maximum Volumetric Efficency point, I like to get there as early as feasible to suit the combo (lower RPM is easier on the block) and then rely on the heads and induction to keep it as close to peak torque for as long as possible...it's the best way to make reliable and consistent street strip power IMHO. This chart is very telling, look at how broad the curve is.....at least 495 lb/ft from 3800 to 6700 rpm. An excellent rule of thumb is if you are at 85-90% of peak torque over a braod RPM range your converter stall flash and shift recovery RPM can pretty much fall anywhere in that range and it won't make too much performance difference, the car is still gonna move. Another advantage for bracket racing is your shift points are not as critical to remain consistent, many of us have seen tracks with slick spots or bumps where we had to short shift to keep from breaking traction. The more "peaky" the torque curve, the more critical the vert has to match up. While your torque curve is flat your power curve is essentially linear (hp gain per every 100rpm)

Have you considered stepping the camshaft up even more? Seems like there is still room to grow.

Dave do you have any info to get a subscription to that mag ? After mine was switched to Muusclecar Enthuiest when Mopar Enthuiest went under I let that mag run out. But I was thinking about getting it again and now with your story in it I think I might get it again. Is the eng done and in the car Dave as of now ? Thanks , Ron

Yes, but I'm in the middle of a few other things right now - A little more duration would seem to help the numbers IMO

Hey Ron - you can go to this link : SUBSCRIPTION PAGE
I wish the car was ready, but I have a 68 Cuda that is waiting to get some work done and have this sucker drop in it.

Nice, easy read Dave. Now stick that thing in a car already!
