DV:, Jim, Jack21:
Trust me, for what you want to do, you need more cam. You will never run high nines with the cam you have in there now. I'm surprised that with the amount of porting that has been done that the cam is that small.
I have a 454 stroker FE (DV: 385 series is another name for the 429 / 460's). I know its not a 460, but the size is the same, and within reason, that's what counts. It has a solid lifter cam (hydraulic rollers don't go big enough, and true rollers are hard on the valve train for the street, you have to pull the lifters out every 3,000 miles or so to check the lifters for wear) with 258 / 260 @ .050 duration and .620 / .626 lift. The motor idles at 900 rpm all day long, never gets over 195 degrees even in 95 degree weather, pulls strong from 2,000 rpm, and makes 585 hp @ only 6,000 rpm.
The heads and intake are Edelbrock that have been ported with intake flow numbers of a little over 330 cfm. The carb. is a Holley 950 HP series (double pumper with no choke, warms up in less than 2 minute in 50 degree weather). By the way, this runs on 91 octane (10.8 to 1 comp.) gas.
Guys: I'm not trying to brag, although I am proud of this engine. The trick to getting all of these numbers is the combination of porting and cam. You should give your heads, intake, cam card and comp. ratio to a builder that is very familiar with 460 engines, particularly the heads. Let him evluate what has been done already, tell him what you expect, and let him tell you what else is neeeded.
I'm signed up for DVSPII, be glad to show any non believers.
