Help identify cam please

once you get back with the compression and rear gear we can be more helpful
take a look at this 360 AMC) dyno chart which give more of a "engine masters' torque curve
this is a 256 @.006 cam (with really short actual seat timing)
then figure how each duration size increase lowers the low end and moves the curve up
you can see how big comp 284 is for a stock gear and mild converter
lots of other good advice above

Hi Wyrmrider!

The motor's been dyno-tuned. Here's the dyno chart. I'm pretty happy with the results. 417 peak TQ at 3700 RPM. That's pretty good for a motor with a fairly stock idle, good vacuum, and assuming longevity. What surprised me was the extent of the power band: 90% of peak TQ from the bottom of the chart (2800) to 5100. 363 HP at 5000. 90% of peak HP from 4200 to the top of the chart (5200).
The HP peak had a bit of a nice mini-band, too. I bet the thing would have had 350 through 5500 or so.
The tires will not be happy about this. By the way, my name is Maurizio.
