Hmm.Well is 6500 considered revving it? I wont be going any higher due to limitations in the bottom end,ie; hyper pistons and probably stock rods.
I could always use the same hall sensor you mentioned above yes? And I know there are crank trigger wheels for big block mopars.
Still not real clear on how it will all work with a couple of tbi units. I plan on using two chev tbi's on a tunnel ram or perhaps I'll have to fab a sheet metal intake. Top end is stage vi max wedge alum heads on a 400,so intake choices are very limited. I think theres one indy intake and maybe two mopar intakes that will fit.
Intake choices really suck for this motor and head combo. It is what it is.
