Inliners International Forums General Discussion Engines clifford intake and holley carb.

For a good driver look for cam as follows:
Advertised duration: 210/210 @ 0.050 lift
Lobe seperation: 110 to 112

On a 261 cid engine the idle will sound good and still have good manifold vacuum. The engine should pull to 4500-4800 rpm pretty good. Pay VERY close attention to the ignition curve as that will determine how the engine performs.

What Holley carb do you have? Compression ratio? Exhaust system?
ALL these things need to work together!!!!
