Lift: .470/.470
Duration: 278/290
Duration @ .050": 218/218
Lobe Separation: 114 LC
Fair idle quality with lope. Good mid-range torque and response in 2400 - 3200 RPM range. Operating power range 2000 - 4800 RPM. Good fuel economy cam with correct equipment. Good choice for light towing. Compression 10.3 to 1 or less. Will work with stock or slightly modified engine, stock automatic or manual transmission. Recommended spring pressure 110 lbs for valve on seat; 280 lbs for valve open. Axle ratio 3.70 to 1 or higher is best. Recommended for mild bracket racing.


Lift: .486/.512
Duration: 282/292
Duration @ .050": 204/214
Lobe Separation: 112 LC
Good to fair idle quality. Good low end torque and response in 1800 - 2600 RPM range. Good low end and mid-range power in 1500 - 4000 RPM operating range. Good fuel economy cam with correct equipment. Good choice for light towing. Compression 9.5 to 1 or less. Will work with stock or slightly modified engine, stock automatic or manual transmission. Recommended spring pressure 105 lbs for valve on seat; 265 lbs for valve open. Stock axle ratio 3.20 to 4.20 to 1 range. Not recommended for racing.

If those are the only 2 choices, then the bigger one for certain.

The stock cam is 273°/287°@S.A.E. - 193°/206°@.050" - .437"/.480" valve lift - 113° separation, ground on 110° intake center line. - in the engine at 118° intake center line. Got that from another very trusted person on a different forum. Both the cams you have listed are pretty small for a big block. First one looks to be a small block Chevy design. Second is better but still small for the Weiand intake. A better intake for it would be a Edelbrock Performer. Post what you want this engine to do so as to get a better cam recommendation from some one. The low compression and stock heads will limit the selection a lot.

With any cam change you need to get the springs recomended for the cam.

I've always heard the Comp Cams 268H cam was a good sounding/good performing cam on a small block. Not sure about on a 460.

Ain;t gonna be able to tell that 268h is in there on a 460. Can only here a lope when cold in my 390.
