    just checking i have a set of h beams that are 454 and was wondering if they would work in the 396 bbc?

    Bob is correct, assuming they are stock length (6.135"). You may want to double check and make sure prior to trying to order pistons, in case someone put something together with some 6.385" H beams.

    This is true. Just because they are FOR a BBC doesn't mean they are 6.135 long. specially when you talking about an after market H beam rod. I never even owed a 6.135 long aftermarket rod

    I did once but there is not any good reason if you are replacing the pistons never use stock length rods the longer the better.

    Specially if your building a 427(not legal SS) because the off the shelf piston selection for a 427 with 6.385 and 6.635 rods is about 10 times as big. And its much easier to hit pump gas compression ratios.

    let me get this straight use a longer rod and you get a better selection of pistons ?

    Horsepower determines how fast you hit the wall. Torque determines the size of the hole you make.

    YEP, much much much biggger selection. Building a pump gas 427 with 6.135 rods is pure insanity

    Right on, the geometry and the dwell time is much inproved with a longer rod.

    Can we agree that there is a difference between a long rod big inch motor and a short rod small inch motor and different ways to make power! ? Mark

    Living power out of the equation, and all the BS that goes with it, including power band, intended usage, intended RPM, blown or unblown, etc. The selection of 427 pistons with 1.75-1.76 comporession height is pure shit. Specially when your talking about compression ratios in the 10.2-10.5 to 1 range.

    I can build more power strictly thru off the shelf piston selection that you can using stock rods and off the shelf pistons. Your hand cuffed before you even start.
