stroker question?

Have to block sonic tested to make sure there are no thin spots. You will need to clearance the bottoms of the bores a little for those rods. I only use ARP studs on the mains for the 4" arms so if it were me, I'd line hone it too, meaning new cam bearings, block hardware, and cleaning after. Upgrade the carb to a 950 HP holley, add a 1" spacer to the intake. I would use a forged crank and forged pistons in that engine and set it up for 11:1 static. With those changes and if there's money for it, get those RPMs to flow around 260/270cfm (stage 2 porting or CNC) And you will be seriously knocking on the 530-550hp door and it should rev ast 6500. Also, you could lower the convertor to something around 3300.
