NEED HELP!!!! I think hughes engines sent me 1.5 rockers instead of 1.6 ratio...ughhh

I have checked, double checked, sextuplet checked the rockerarm geometry on my 340 with 360 j-heads. Pushrod clearance was done, valve stem wipe pattern is perfect, spring retainer clearance is fine, pushrod-rocker adjusting screw geometry is fine..........everything is perfect except I do not get the advertised valve lift. I followed the setup instructions to the "T"

Dave at Hughes Engines said I should be getting the advertised lift numbers or at least very close. He said it was possible that the roller rockers may not be 1.6 ratio like I ordered. They have the correct part # stamped on the arms themselves but I am getting nowhere near full valve lift. Some douchebag (human error) at the supplier (Probe) probably stamped them wrong. :mad:

By the way I am using their adj pushrod tool and solid adj lifter tool.

Here are the cam specs from the card. It's a hydraulic roller cam for use with their retro-fit roller lifters in a 340

Grind number HER2228ALN

Sweet Spot RPM 2500 - 6400


The best lift numbers that I could get were .508" on intake #1. I checked a number of other exhaust and intake lifters on the same bank. Based on the 1.5 ratio #'s (in bold red) I would assume that I received 1.5 ratio rockers. I'm not engine genius, but it is hard for me to believe that I am +/-0.036" off. There cannot be that much angle deflection if I have everything setup according to Hughes' instructions.

This is my dilemma. I can't get 1.6 rockers from Hughes. Hughes has been good and offered to send a 1.6 rocker to double check mine, but they don't even have any available at this time. Not even to sell. The reason is because they took over the manufacturing of these rockers and are not up to speed on production yet. My current option is to send a rocker to Hughes and they will check it on their bench.

My questions to my fellow FABO members is......DOES ANYONE HAVE A SPARE SMALL BLOCK 1.6 RATIO HUGHES ROLLER ROCKER THAT I CAN BORROW????? :notworth::notworth::notworth:

Thanks in advance. Buttoning up this engine is really holding back my resto at this point.
