SBM Roller Lifter Choice

Whenever you the your Comp lifters out, it'd be useful to know if you have the "flat" lifter or the "smiley face" lifter, referring to the body over the wheel. This is a "flat" and a "smiley face" dips down like a smiley face. It's very apparent which is which.

You're giving good info and great descriptive pics. Thanks.

The morrel solid lifters I use, cover the wheel and that's why they work without bleeding oil psi. But they are a .7 something wheel. I'm not complaining about that on the street because at this level and frequency...any negative byproduct stated by some will have about zero effect. I run .575 lift herbert cam, they call'em their "248 special grind" kind of a soft solid roller or aggressive hyd..lol.. depending if you're a half full or half empty person. Mine was ground [email protected] 108 la +4 degrees. 281 running duration iirr. I'm very happy with it and its QUIET, sewing machine quiet.
I run the k800's 220 closed and 490-500 open. Setup at 1.70 inst. height.
The 340 engines are the worst for oiling issues because of the crummy finish work
