8 degrees? Maybe 108?
Sounds like a 3500-6500 rpm power range with that engine size.

Edit: LSA 108 I'd expect it would pull well from 3000-6200 w/ peak HP around 5800. "Your results may vary", but I'm basing this off some older builds I've done.

Sounds like the Comp XS282 cam...as said 5800-6200 is where it will max out at.

I'm sure you understand that they don't really "start" and "finish" making power. There will be a range in which that combination will make the most average power. Obviously, the range that matters is defined by the shift point and shift recovery rpms. If you are back into the converter after the shift, you need to take that into account.
So generally speaking, that combo will probably make peak power at 5800 - 6000ish, IMO. Best et might be a shift as high as 6300 to 6500. I would think that motor would feel pretty sharp at anything above 2500.

I had a 446 on the dyno in March, 9.5 compression, ported 456 heads, mopar mechanical cam http://www.summitracing.com/parts/dcc-4120661ac/overview/make/dodge It's on a 110 CL but very close to yours. It made 500 ftlbs of trq @ 3500, with a peek of 544 @ 4600 and over 500 hp. from 4900 to 6400 rpm. with a peek of 520 hp.@ 5600 rpm. This was a refresh on a motor built in 1987 from the pages of Mopars engine book, TRWs, blueprinted bottom end, very basic. Your 108 CL will narrow the power bands 300 rpm. or so. I hope this helps,
Have a great day Iowan

Moparts tech page, visual speed/gear ratio/tire size portal. May help you get closer to your goal. Otherwise, talk to the manufacturer of the converter you are purchasing, give them the specs of your combo and go from there. Once the selection has been made, FINE TUNE the combo for best power/performance, without running on the "ragged edge"! Good luck.
