Big block hydraulic roller lifters, which ones or whats your opinion on Comps ?

[68 HEMI GTS]

I’m actually building a big block Chevy 496 with AFR heads and a Hyd roller as well. I talked with Chris Straub about the combo and bought most of the parts from him. Oil is very important with the hyd rollers as well. He looks at a number called centistoke. He says you want lower than 15 measured at 100c. I guess the Driven works very well. He has some impressive combos.

Something to keep in mind and often overlooked.
