also what is the mention of the rhodes lifters being used, i thought this plate system was specifically for the sealed power type roller lifters. just curious & sorry if i missed some details in the 7 pages of this thread.

We tracked down that Rhoads modifies speed pro 2148 lifters and converts them to Vpro and Vmax.
It does appear the from 80TA’s efforts the small base circle cams that are pushing the base circle limitations of the 2148 lifter are problematic with the plate, on his combo the plate is a little to wide. I found some blocks that the top oil hole on 2148s gets exposed at max lift on some Pontiac ground 1.88-1.89 cam core too, but it is dependent on how the block is cast, later blocks appear less to have slightly shorter lifter boss’s.
Hot rodding most everyone likes to push the limits of stuff, JMHO but the lift range the plate system and 2148 lifter will work best on should have started life as a small block 1.86 ish cam core (not bigger the 1.889 Pontiac) using lobe lifts .31-.35 looks to me like good combos with the plate system and the 2148 lifter with most any Pontiac block.
