446 cid, ported RPM heads, 10.2:1 compression
Solid mechanical Comp Cam custom grind:
duration @.050 intake 244 exh 252,
LSA 8 degrees,
Gross valve lift intake .520 exh .541,
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.
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,
