Basically if you need more than studs and aluminum caps...you probably need an aftermarket block.
I agree ^^ . At 650 hp with standard stroke it will be fine, buy some BCR ali cap and some ARP studs.
I have a 446 LY rod, cast crank engine with stock caps(my first race motor) that has a lot of runs on it and over 150 nitrous passes, best pass 9.69, it has a sleeve due to a pin walking out and wearing through the bore and in that pot is a manley piston that I shaped myself with a grinder to look like the 7 other TRW's
That engine is now semi retired running NA 11.00's in my sons Aussie A body .
