    Piston help

    Does anyone know of a site or have a program on their pc where you can put the specs of an engine in to get some figures out

    Trying to work out the best combo but with small cc heads BEFORE ordering the parts on a B/B chevy

    Robbed this from the site but we have 98.4 cc heads

    COMPRESSION:
    w/100cc Head: 9.86:1
    w/107cc Head: 9.35:1
    w/110cc Head: 9.16:1
    w/119cc Head: 8.48:1

    or this from another

    Approximate compression ratio 8.67:1 with a 100.9cc head with the dome removed, 9.98 with a 100.9cc head.

    And thats with the same pistons

    Confused as me

    Vince,

    Try asking on the performance section of chevytalk.com there is a guy called Grumpy who knows pretty much everything and anything about Chevys motors, sure he will be able to point you in the right direction.

    Everything you need is here, assuming you have the block, piston and head gasket specs

    As long as you know the bore, stroke, head gasket thickness and chamber volume it's not too complicated to work out the compression ratio.

    Let me know if you want a hand working it out

    Think weve got it sorted now after asking over on the chevytalk forum (sorry Si) thanks Paul

    Looks like with the smallest domed piston at .140 its going to be around 10.16-10.66:1 depending on the deck height but thanks for the info and offer of help and if we get stuck again (proberly ) ill be back in touch
