length of custom pushrod

Aaron, other than stock pushrods or converting from solid to hydraulic lifter, there is no way to guess at pushrod length regardless of your combination. You need to find a pushrod checker (adjustable length pushrod) to measure for sure. If your pushrods are a tiny bit too long or too short you might be able to guess....but I wouldn't. Sounds like you're close though. tmm
Sorry I for got to say, its a hydraulic flat tappet. I'm using a comp cams adjustable lenth checker ball and cup style and subtracting the cup depth, and I come up with 7.125.
