Roller lifters

[408 Nova]

Is the main advantage of larger diameter lifters to help with pressure angles and block wear?

Getting a block drilled for the SB2.2 lifter pattern and would really like to know what diameter lifter is best to go with, with the .903" being as big as I would ever go.

And all that being said, what brand lifter is everyone using?

[mt-engines]

go .937 with an .850 wheel if you can.

jesel or morel makes nice keyway lifters. crower enduramax are nice, isky redzone etc

The main advantage of a larger diameter roller lifter, is the larger diameter wheel that you can fit on it. The larger diameter wheel, produces less side loading on the lifter.
We have plenty of lifter options.
Our .842" and .875" lifters have .750" wheels.
Our .904" lifters have .810" wheels.
Our .937" lifters have ..850" wheels.

Our lifters can be upgraded to bronze bushings, or our steel-on-steel bushingless wheels

Bam is also a good lifter!

Yes, I have a customer that builds a lot of turbo street engines, and he's been using them for a couple years, I don't know how many miles they're putting on them, but we haven't had any issues.

Will going to a larger wheel change the cam performance?

[panic]

It will tend to stretch the window at both ends of the duration.

There would be a very small change in performance.
Using my 262@.050", .440" lobe lift profile
If you went from a .750" wheel, to a .810" wheel, here's how the durations would change
@ .012": +0.66 degrees
@ .050": +1.22 degrees
@ .100": +1.42 degrees
@ .200": +1.38 degrees
@ .300": +1.05 degrees
@ .400": +0.60 degrees

If you went from a .750" wheel, to a .850" wheel, here's how the durations would change
@ .012": +0.80 degrees
@ .050": +1.79 degrees
@ .100": +2.29 degrees
@ .200": +2.23 degrees
@ .300": +1.69 degrees
@ .400": +0.91 degrees

Mike
thanks Is it true that OE GM rollers (L31 & LS) have a wheel that's only 0.700" diameter ?
