Should be pretty spot-on out of the box in terms of jetting. Most people that fiddle with jetting are usually just trying to cover up some other deficiency like a mis-matched cam, lame ignition, wrong gear / stall, etc...

I was gonna go with the 750 AVS(minimum)... 3.73 gears with ratcheting spool, reprogrammed th400 with 2800 stall, 383 with the AFR heads. Cam has .496/520 lift @ 224/234 duration @.50. Should work well I'm thinkin.
