One thing you'll loooove about the BBF is that it's too damn easy to make that level of hp with one....it's just about as easy as throwing together a SBC. :mrgreen: You can use a lot of stock parts, if that's what suits.
It's almost as easy to build a stroker, and not all that much more money...although it's real easy to get carried away & start adding aluminum cylinder heads, roller cams & corresponding parts, & so forth.
A couple of threads that may help for starters:
Note that at your desired power level, it's basically cam/headers/intake/carb/mild port work on stock heads. Intake choice depends somewhat on the cam and the weight of the car/gearing; also, if you use D3VE heads, you could use the Harland Sharp pedestal-type adjustable roller rockers offered by a board member here, Randy Malik, rather than go to the effort of a full conversion.
Some of the builds mention D0VE heads; at your power level, D3VE heads will work as well with the same port work, as long as you use different pistons to get the same compression, as the D3VE heads have similar chamber shapes but are larger in CC. The D3VE heads are more common, and usually much cheaper. C8VE & C9VE heads are more or less equivalent to the D0VE heads. These are the common, everyday BBF heads you're liable to find in the boneyard. Avoid the '72-only D2VE heads for what you want to do.
Lastly, all these builds assume good machine work & assembly techniques. One example is that, depending on your 460 block, and its deck height, you could end up with the piston deck being quite a bit below the deck at TDC. Without measuring and correcting this, you will likely end up with less power and possible detonation. You may already be familiar with all this, but I thought I'd mention it....now's the time to ask.
