I have a short block BBC 454 on the motor stand bored .60 over, fully ballanced with a cast crank, stock re-worked/shot peened rods. crank journals have been line honed, all ARP bolts including main cap studs.
My motor guy says 650 no problem on that bottom end and he knows what hes talkin bout but I figured id throw it out there and see if anyone had some advice.
Heres my question. I have a 74 rogers and would like to see 85-90 mph outta it. It does a solid 70 with the motor i have in it now (425-450 hp est.) Ive already had the pump redone and set up for it except for maybe an impellar change, just wondering if 650 hp would get me there (85-90 mph) or if it would be worth investing in a steel crank, some new rods and have the caps splayed if id need more hp.
Any oppinions would be great!!
