    just wanted some feedback on how may runs some of you are going on your rods. I didn't make as many runs this season as usual. and was thinking I would leave the motor together a while longer. rods are grp pro material with the bolt upgrade 2.950 stroke. sbc

    I have the same GRP rods with a 2.850 stroke and made 150 runs in 2 years @ 10k RPM with no issues. This might not be the ideal response or best thing to do but, the engine just came apart and bearings were perfect.

    Good Luck

    same situation. last year I made a 130 passes with no issues, this past season only made 72 passes. so I think i'll leave her together for a while longer. I figured 150 passes was safe. just wanted to see what other were getting. thanks. rich.

    rods

    I know most won't believe this, but bought an SS\CS 291 used in like 97, ran it at a few div races, and for 7 years straight at our local track every weekend, 1\8th mile, and a couple of other div. races with GRP rods, and just changed them in 2011. We figured we had well over 600 runs.
    I know, but they didn't break, so we changed them in time. You could have never changed bearings. They looked that good. But, we did.

    What is Woody's opinion (@ GRP)? I take mine out at about 1/2 of what he says because i start getting nervous (3.625 stroke, 8,000RPM small block)
