  • WHAT LENGTH PUSH RODS WITH H8002 BLUEPRINT HEADS AND DO THE ROLLER LIFTERS COME WITH THIS UNITI

    Asked by: GOODYS
    This engine does come with the roller lifters and it is recommended that you measure to get the proper length. It will probably work with a stock length pushrod.

    When ordering all recommended parts, what push rods/ length do I need and what rocker arms? Which efi system and computer shall I go with which will bolt on the recommended intake manifold?

    Asked by: Rayjay420
    You will need to get pushrods for the cylinder head you decide on, same with the rocker arms. You can look at the FiTech EFI systems - http://www.jegs.com/p/FITech-Fuel-Injection/FiTech-Easy-Street-EFI-600-HP-Throttle-Body-System/5109244/10002/-1

    Will the cam included with this short block work with aftermarket EFI? I'm considering Pro-Flo sequential from Edelbrock.

    Asked by: LouDady
    The Pro Flo can be tuned to work with this engine.

    Will this engine fit in a 1987 chevy/GMC 1500 pick-up and can the compressiobn Ratios be held to 9.7:1 to burn pump Gas

    Asked by: DRay
    This engine will physically fit in the engine compartment of an 87 Chevy 1500, however it does not work with factory EFI. We are not able to change the compression ratios.

    Can this engine accept the stock TPI injection that is controlled by the computer on a 1987 GMC 1500 pick-up?

    Asked by: DRay
    This engine will not accept factory fuel injection systems. For use with the 87 injection system you may use GM goodwrench 87-95 truck crate motor 12681430
