    order the comp cams pushrod length checker. make a solid lifter out of a stock lifter, throw checker (soft) springs on a cylinder along with the rockers you're going to use, play with the length until you find the one that gives you the least amount of rocker travel and gets the contact point of the rocker as close to the center of the valve stem as possible. unless you've done something really out there it'll probably end up being an off the shelf length.

    as for pushrod type smith brothers has a good chart that shows what you need for a given spring pressure, rocker/lifter combo and rpm range.

    check with [MENTION=5311]easystroke[/MENTION] as I gave him my 351W pushrod length checker when I was done with my 408. He might be able to help you. I have all mine but you would have to check the length first to know what you need.

    you will need to determine what style lifters and rocker arms and heads you are using then you can get a ballpark of what length checking pushrod you need. they aren't one sixe fits all chacker pushrods and have a range they can be used in.
    For example a lot of aftermarket heads like AFR have the rocker arm geometry different than a stock SBF and can be used with a GM pushrod length checking fake rocker arm like the one ProForm sells.
    I have a length checker pushrod here if the one Scott has isn't the right range this one I have might be.


    What heads? What rockers? What Cam base circle? What block? What lifters? Stock or Link bar?

    Well I'm running a hydraulic roller cam stroked 408, CompCams Ultra Gold 1.6 roller rockers, and TrickFlow 205 11R heads. I was going to order the 7.5 - 8.7" length checker

    [MENTION=11357]RedRaider713[/MENTION] Is this block an original Roller block casting? Not one that needs a retro-roller cam?

    What lifters? Link bar or stock style? And as mentioned by Matt(85coupe50) what base circle cam?
