I am about to rebuild a 460 and want about 450-500 realistic hp at the crank. Just wondering what people would recommend bc this is my first ford build. I've done chevys and mopars but no fords. Any dyno proven combos would be great. Don't want to get to crazy to save my pocket. I would love a stroker and blower but being real. Laughing Going in a 70 torino using a C6 for a street/strip app.

Thanks

Look around on this site: http://compcams.com/Community/Articles/

Scroll down to the ford section and see if there is anything that can help.

They just rebuilt a 460 on Horsepower TV on Powerbock last week that cranked out 477 horse (370 was stock). They used flat top pistons, a high rise aluminum manifold, and a mild hydraulic flat tappet cam. Built the whole thing in their budget build section of the show for a little over $2,300 (most of that in new parts and machine work as it was a former boat anchor being full of water).

You can down load the show for $3 or buy a DVD of it for $6.

There is no reason why you won't make 460 HP with headers, Intake, Cam and a bigger carb. The stock Carb was around 700 cfm.
1970 specs were 10:1 with small chamber, and 375 HP with a small juicer cam.

Anyone on here at any power level care to give their setup on a BBF. Just want a look at all sides.

Any tips/secrets over the build process that most books will not tell you. I have heard the oil system sucks on these motors and you should drill some of the holes bigger to allow better drain back. Any one heard of this? Cant remember which holes on the block it was talking about. Im thinking some where in the cam valley.

Sorry if im beating a dead horse. Thanks

You would need to verify the machine work of the block's oiling system. These were machined by union employees not CNC machines. There is the possibility if the block wasn't set up on the registers just right for the oil feed holes to barely touch when the journals intersected. You would need a mighty small inspection scope to run down each oil journal to check it, or look inside under the cam bearings to verify they have one round hole where the two bores intersected and not two overlapping. If the feeds are not large enough you could starve a main or loose a rod for lack of volume.
