Lets assume you are not going to run steep gears or a big converter....because they can cover up some serious sins.....

I would seriously re-think running the modman...at least with a single carb....unless you run a double pumper and gears.

Theres no question the large plenum creates bottom end torque issues.

Trouble is...these issues are made worse by cams that dont "favor" low end power production.

The factory 6.1 cam has a pretty small duration and would no doubt make better low end than the bigger off the shelf stuff.....but you'll lose top end....its a pretty mild cam

If your not chasing 1/4 mile times...Id look at one of the smaller Comp grinds....maybe get Modern Muscle or Comp to grind it on a 110 lsa...that way you'll have a sharp responding cam which hopefully wont be too bad down low.

Basically the less the duration, the less problems down low.

Be prepared to run a lot of initial timing also - as cylinder pressure wont be great with the modman.

I started at 10deg initial and ended up at 21 deg initial going to 25 at 3000 rpm with no detonation issues or kickback against the starter.
