Donny,

If you have D0VE heads with CJ sized valves, then 500hp is easy to get to. This assumes that your D0VE heads have been ported (I would think so since the larger valves have been fitted).

500 hp with a dish topped 429 will take some good planning. You would be better off using a 460 crankshaft since it opens up endless choices in pistons while there is only 1 common forged piston for the 429. Are you stuck on the 429 shortblock as is/will not disassemble? Or will you be rebuidling the short block too? Are you absolutely certain the shortblock is a 429 and not a 460?
