Hylift B2303 lifter travel

Anyone ever measured or happen to know what the travel is on a Johnson Hylift B2303 lifter?

Or asked another way, what would be the target pre load adjustment distance?

I think you are over-thinking this...just follow the instructions for the tpi you have, if you don't know it, get a tpi gauge or count them.

I'm not asking about push rods. I know that part already. Asking about the lifter, really. I will take Larry's advice and try .140 pre-load, but I was curious what the total travel of the B2303 is. I haven't found it anywhere.

.100 is the target BUT square lobe cams have the ability to get noisy at this depth. .140 or .150 is used to help tame the clack when hot, Evo cylinder and heads grow when getting hot moving the lifter depth of .100 to more of .060, setting .140 or .150 puts the plunger back on center after the growing process.
Know .150 is the setting on any lifters for Wood cams and EV27's have the same cam lobe profile, remember members posting .140 is the norm for Johnson Hylifts and most likely just adjusting for growth like being mentioned earlier.
