Fuel dripping out of primary's

Cliff Ruggles:
The cam will probably have the engine "feel" pretty strong in the mid-range, but it will not be very efficient at idle and low rpm's due to the tight LSA.

For truck applications we need good idle, off idle and broad torque curve.  Here is a much better cam choice for what you are doing, if you get around to having to change the cam out:

Here is another, modern grind with emphasis on smooth idle and low rpm power:

and one more that works really well in a low compression 454 truck engine, and smaller cid engines like yours if you have around 9 to 9.5 to 1 compression:

hope this helps some......Cliff
