I think that you'll find that the flat tappet cam of today is nowhere near as forgiving as it was in days past. Even with the most meticulous attention to spring loads, lubrication and break in...

No I didn't see see that one I just noticed the regular Kaase pump was now made in aluminum and not cast iron.

I've had very good results from using the Yella Terras and while they are pretty expensive they are a very high quality rocker. I think that they are WAY overkill for a typical hydraulic roller cam...

Take a look at these pictures very carefully and you will see the pushrod out of plane problem that is caused by having the taller hydraulic roller lifters in the engine. This is a 545 Ford with a...

No it isn't. The flat crank makes the V8 vibrate like two four cylinder engines hooked together. Four cylinder flat crank engines have a rocking couple and vibration issues and that's why you never...

Maybe you have a crank that was ground undersize and didn't know it and the engine now has STD bearings.

I don't think that the amount of lash has much to do with contact velocity. That's all in the design of the ramp.
