pushrod length. ...will I be ok... Just measured my pushrod length for my build and came up with 7.375. I already had 7.4 hardended chromolly rods and installed them and torqued
everything down and everythibg seemed good. Will I be good with 7.400 or should I order 7.375 just in case?

I would say the 7.375. Just because most people run their ls7 lifters at .080 doesn't mean it is correct for every application. Your .050 preload will turn into around .040 when its warm which is a good number for that cam.
IMO, .075" pre-load with the LS7 lifters is fine so stick with the 7.4" PR's. If the valve train ends up being rather noisy with the .075" pre-load, then you might consider getting the 7.375 PR's.
