Horsepower estimate
What hp/torque numbers can I expect from the following build :
460 Block +.030
SpeedPro 9.14:1 CR Pistons
DOVE Heads ported & polished, and milled (w/roller rockers)
Lunati 214/224 .516"/.534" cam (1,500-4,500)
Weiand STEALTH intake + Holley 750cfm double pumper
Headers
If anyone has done a combo like this or close to this what kind of numbers did you get for your build?

Whats the flow numbers on the heads? More importantly, how much were the heads milled since thats relative to final compression? What type of headers and size of primaries?

We need stock flow numbers in a sticky in this forum. I can never find them when I need to DD something. If anyone has flow numbers for stock DOVE heads post them up please.

Assuming any decent porting on the exhaust side, and some type of 1 3/4" or 1 7/8" header...425hp and 500lbft should be reasonable with that build

ok heres what the dd says with your setup(assuming a 112 lobe center and 108 centerline) with 9.3 comp ratio, the came above, 750 with dual plane, headers, stock doves with stock valves, bored .030 over
2000rpm 196 hp/513 tq
2500rpm 243/510
3000rpm 284/497
3500rpm 315/473
4000rpm 318/418
4500rpm 295/344
5000rpm 264/277
the heads are really choking you....at least do something with the exhaust side and throw some 2.19/17x valves in them
with some mild port work and larger valves your lookin at
2k 197/517
2500 248/522
3k 298/521
3500 345/517
4k 380/499
4500 394/460
5k 385/404
5500 355/339
