Hey Jim, here is what you engine will look close to on the dyno. I found your cam model here #292H

and here is the detailed spec sheet on it

at the flywheel it looks like the peaks are
422HP@5500 and 468TQ@3500
you've got a big fat torque band that will kick you right in the pants
Big torque is more a function of stroke. Big HP is more a function of heads and rpm. A 358 can be 750HP at 14:1, with a 8000rpm screamer cam and massive flowing heads. It can be 650HP using 12:1 with a screamer cam and big heads. It can even be 620HP on pump gas with serious ported heads and 7500 screamer cam.

From most of the posts I've read on the cobra boards, 90% of people prefer the big torque engines. They have a lower powerband that you feel in everyday driving. The car feels faster and accelerates like a mad dog. Most racers prefer the opposite. Piles of 2000rpm torque is not that useful on a road course and tricky to use since there is so much of it. Instead they prefer to get higher HP at the trade off of less torque. The car is then driven in the higher rpm ranges where the throttle is easier to control.
The drawback with strokers is that as you increase stroke, you increase the piston sidewall loads to a greater and greater degree. This robs power due to higher and higher levels of friction. It can also cause the piston to be less efficient at sealing the chamber. The piston is travelling a greater distance and moving at a faster rate so strokers tend to have lower redlines to keep piston speed in check.
The drawback to screamers is that you have to create parts that can handle the forces that come with 7500-8500 rpm. You have to use a flat tappet cam or solid roller since hydraulic rollers lose the ability to function. Lightness becomes important. Screamers tend to feel sluggish or flat down low in every day driving since they are outside their powerbands which are shifted right on the graph.

PS want to see some wild heads?
Jason FFR 1976 turned me onto a shop that does custom programmed CNC porting of all the major head lines.

How about a set of TrickFlows (TW not Rs) flowing almost as good as a set of Yates
how about 313 / 254
