    QTY

    Can I not use this block for a high boost build ?

    Asked by: Anonymous
    Hello Tim, we would not suggest it. It does not have the proper rings or clearances. On top of that, the rod bolts would not be the upgraded bolts for a high boost build.

    How much hp can this setup handle 

    Asked by: Tim c
    Hello Tim, that's a loaded question that has allot of variables. With the parts provided 800HP is not out of reason.

    Can you get this with higher compression. I have 70 cc heads and looking for 11.5 to 1

    Asked by: Gene
    Hello Gene, that would have to be a custom build as there is no way to get there with the piston offered.
