    Does this engine come with a fuel pump rod? If not what part number is best. 

    Asked by: Jeepcjguy
    This engine will not come with a fuel pump pushrod installed, but any pushrod for a standard Small Block Chevy (no bronze tip) will work with this engine and camshaft.

    Is this engine available with a high torque, smooth idle cam?

    This engine cannot be had with another cam but this is a fairly mild roller cam that starts making good torque around 1500-1800rpm.

    What is an Hypertuetotic ( I know it’s incorrect spelling ) piston .

    Asked by: Freud
    Hypereutectic pistons are the most common for mild rebuilds. They can handle more stress than the standard OE cast pistons but they are not as strong as forged. It's a cost effective middle ground for a good piston.
