Re: 400/406 Builds
Depends on what RPM the engine will operate. If you will see some upper RPM pulls a 750 will be great. Hell a 750 cfm like a 3310 would be perfect if you ask me.
I'll tell you though... that Thumpr cam is gonna want a crap load of initial timing. Probably close to 22 to 25 degrees advanced. Got a buddy yarding the Thumpr out of his rig in exchange for a Comp XE cam. Only pulls 5" to 6" of vacuum at idle.
