i was thinking of dry sumping it, the cam's rpm range is 4000-8000 using adjustable solid rockers and all the usual head work, 390 4bbl holley, EDIS with megajolt, pro timing set, vernier gear ect, i was hoping to get away with just a balance on the bottom end, i might have to work out the piston travel/speed ans see what i work out. last seasons X-flow i built revved well into the sixes and still wanted to pull, the bottom end was basically standard. looks like more researching i want to get stuck into it ASAP.
