    John I need your advive on a 521" used for mud & Dirt drags.
    This was a performance Automotive wearhouse /PAW 521" Dinosaur kit.
    The 521"is made of the following.

    Ross 4.470 bore with 28.65 cup ,
    4.150 stroke cast crank
    Edelbrock 75cc performer 60679 heads
    singel 4 victor intake 4500 top, 1050 Dominator
    The engine was specked for 10.5 to 1 on compreshion.
    Know we are looking to get as much power as possible out of this combination and am looking at doing the following.

    Flat top or dome pistons
    I also have a Howard solid roller 410-108, 270 deg 108 Lobe center 708 lift

    any advice would help
