My 65 Valiant.

Any ideas on what I should expect, power wise, from this setup? It's a 1960, 361 Golden Commando, 383 forged crank, .030 over, 292/.509 Purple Cam. Factory 69 440HO manifolds, thru 2.5 exhaust to 1 chamber flowmasters. Electrick cut outs before the cross over in the exhaust. Pushing thru a 9 in converter, 727 reverse manual valve body 727 transmission to a 8 3/4 out of a 62 Dart with 4.10 gears mini spooled.
