I've had the pleasure of dealing with Dave a couple of times. Great advice and a good education came from those talks. I've been a big fan of their products ever since. As a matter of fact, I chose their 294FDP grind for another motor completed a few weeks ago. It can be heard running in this 383 video that was just built for my 69 car. It'll be topped with a Crossram and is also running the cloned Trickflow -175 heads. They actually flow really well.
Can't go wrong with Crower!
