    Pistons I like endyn, and for rods I like crower. Stick with 84mm bore. I would consider resleeving since your motor is apart anyways.

    If you're going all motor, don't bother with resleeving. You'll be fine as long as you don't cheap out on the rest of the build. Bore it out to 84.5mm to clean it up, then slap in some Endyn Rollerwaves. I have a set of Eagle rods that I need to sell (used, but perfect condition) that will fit your engine.

    I was running good old 93 octane. Exxon on Burnet and 183 has the best price, along with the Exxon on 51st and I-35.

    Oh, are both accounts yours? Give me a call on the phone number I sent you by PM, and we can talk.

    :)
