Newbie Here. I just bought a Scout II with a Ford 460 and need some carb. advice. The 460 is spec. out as follows: BIG BLOCK 460 BORED OVER 30 (ABOUT 500 HP-600 FTLBS TORQUE)
WHOLE MOTOR IS BALANCED CLAY SMITH CAM ( 2240 DURATION, .525 LIFT) ROLER ROCKERS AND LIFTERS DOVE HP HEADS HOLLY 650 DOUBLE PUMPER ALUMINUM WIELAND STEALTH INTAKE MSD TIMING CONTROL MSD IGNITION ALUMINUM RADIATOR 4 CORE My buds tell me the 650cfm is too small to realize the full potential of the 460. What do you guys think?

I think your VEHICLE is too small to realize the full potential of the 460.

Lugnut, Thanks for the good advice. My Scout hasn't arrvied yet. I bought it on eBay. The specs. I quoted came from the eBay ad, which I shared with some friends who mentioned the carb is too small. I'll do the goggle search as you suggested. Thanks again. JIm

Here is the standard formula for figuring out carburetor size.
CFM = (cubic inches x rpm) divided by 3456
VE = (cfm x 1728) divided by (cubic in. x rpm)
Another CFM but takes into consideration Volumetric efficiency
CFM = (cubic inch x rpm x volumetric efficiency) divided by 3456
This should give your friends something to do for a couple of minutes.
