.937 lifters?
 

I'm pretty sold on the idea of using a .937 lifter. Im just wondering if anyone else is running them in a boat. What kind of service time are you seeing? What lift cam and RPM range? It's a big investment but I think it's worth it. I dunno maybe somebody has more insight.

Need to put lifter bushings in with the oil band around the outside for big lift cam. Just ran into the problem with my engines the lifter goes up and shuts the oil off to the rest of the lifters. And the axel goes into the oil gallery. Cam lift will be around .800. You also need to get the cam ground for the .937 lifters and you should do 55mm cam with it. Works better.

55mm is the plan. Who's lifters are you using? Jetway?

Sorry. Keyway?

It was going to be tie bar lifters till I found out not going to work rite. Now it will be keyed lifters.

Yeah that's what I was gonna do. Isky keyed with bushing. Glad I only have 1 motor.

Ya the ***** is I already had them done without the bushings to .937 now it has to be done again with bushings.

How much are you getting whacked on the head for machine work?

First time 450 each. This time ill probably do in in my shop. First time I also had the cam tunnels opened up for 55mm cams. Cam tunnels think where 650 each.

What is the gain from the bigger cam? Stiffness?
