seems to, yes.The lifter spider, i.e. roller ready block?
L31 Vortec spec would be a safe bet. GM LT1/4 Hot Cam would be nice but not stock ECU friendly.My biggest concern is what cam would play nice with the '90 truck computer if i did go roller.

True.... Didn't think about the RamJet/marine cam. Good mention 😎This. Ramjet/marine cam should also be OK, it's barely bigger than the L31 cam. Can use whatever LS lifter is cheap now too.
