I heard all of the same stuff and was getting spun.......Finally I just said "F" it. I used the best assembly lube (and lots of it) checked all of the lifter bases and cam lobes.....Installed them all and test spun them with a speed wrench and observed rotation. Top quality high zinc break in oil and primed the hell out of the oiling system just before fire up.

I tested my carb and ignition system on a mule engine to avoid any problems there.

Set my timing to fire at about 10* BTDC and primed the carb with fuel. She fired right away and I took it up to 2500 RPM and advanced the timing to 34* BTDC. It ran like a champ for 1/2 hour as I varied the RPM from 2000 to 3000. Shut her down and drained the hot oil and changed the filter. Re-filled with Lucas Hotrod 10w30 and a new filter and ran it for another 1/2 hour varying the RPM.

We'll see what the future holds.

The way I looked at it, they sell a **** load of flat tappet cam and lifter packages.......We hear of a few failures here on FABO. To me, I went for it...But That's me. :)
