i thought i was sure about the 850 with the help from a couple people on this board bt i called the guy that i bouht the motor from and he said 750 double pumper, and that an 850 will be too big and i will lose low end power, so any opinions on this are welcome. gas mileage is of no concern, horsepower is only concern, not concerned with top end speed, just basically quarter mile runs, thnaks, sean

oval port open hamber heads, decked, 3 angle valve job
comp 292 hyd. cam, lifters springs to match
weiland SQUARE PORT intake(gonna get swapped for a performer rpm, if thas teh best for it)
block bored 30 over, honed
10 1/4 compression TRW forged pistons
double roller timing chain
crank ground and degreed
stamped steel roller rockers(these are getting replaced also, how do i find stud size?)
new pushrods, fuel pump, ARB bolt kit
