First, do you know how high the motor will rev to and how much boost it is making and the last thing is which type of fuel and total ignition timing? I've made over 500 HP on N/A motors with one 850 Holley doulbe pumper with 906 (iron) heads and 9.7 to 1 or less compression ratio. That motor shuld make at least 600 HP at 6000 RPM with 6 to 10 lbs of boost on pump gas Tell him to be very careful with that stock block, they are easy to blow the main webs out of them

used to have an almost identical combo, mine was 1:1 driven, i would say he should be in the 700hp range

he bought it like a pig in a poke. was a 12.5 piston, tunnel ram motor and it seems they swaped out the pistons and put the blower on it. we went for a ride and it when he let off, it back fired and blew the header pipe off the flange.
