Thank guys my block is a 73 455 bored 30 over so 462 with butler / ross 9.5 to1 pistons and eagle 4340 H beam rods block is being filled along with pro gram engineering 4 bolt main caps all ARP hard ware to try and keep her together as of right know stock crank but I am thinking of forking out the money for a nice forged crank. I was originally looking at the KRE hp heads with the 64 cc chambers to gain the 12.5 to 1 compression running E85 and Nitrous. As far as intake I do have a 4150 victor that I am thinking will need to port matched for the heads carb and cam I am still looking for good choices so be willing to take suggestions there to. As far as chassis it will be set up for the added power as well stiffen the chassis / currie 9 inch stock suspension IN the rear / tubular upper and lower a arms / tires in the rear are Mickey Thompson 275/60/15 drag radials I hope this enough info and please feel free to add your opinion on things.
Thank you guys again for your help and like I said 550 was the goal if it makes more power and can stay together even better not going to try and push her to much revving it to only 5 to 55
