Ok... Here it goes!!! Windsor block with stock bore and forged probe dished pistons... I am taking out stock crank and rods... I have forged H beam rods with ARP 2000 bolts and a cobra crank I need to get balanced... I was considered getting an aftermarket harmonic balancer and flywheel since I need new ones anyway... I am going to buy billet oil pump gears and arp main and head bolts.. Is a main support worth it???? I am looking at over 500 rwhp... I am going turbo or supercharger... I have stage 3 ported and polished PI heads and SHM blower cams... I was looking at reichard racing intake manifolds... I need to know which head gaskets to buy... Is there anything else you guys think mayber I should look into... I plan on keeping stock rear end with 4.10 gears... And what you think on high boost I can put down horsepower wise????
