Its been a long time since I have messed with hyd lifters in a race engine. So here's my story and I'm sticking with it. I lost a lobe on my roller cam so to finish out the year decided to put in a hyd flat tappet cam that I have and am now ready to adjust the rockers before I put the manifold back on. Here is what I was told bring the no 1 up to tdc and tighten the rockers so you can just spin them by hand then go a half turn for adjustment. Then of course follow thru for the rest of the cylinders by bringing up each piston to tdc and doing the same. Does this sound reasonable? It is about a 550 lift cam with so called "anti pump up lifters" I ran this cam in a stock bore and stroke engine and it ran quite well a few years ago befor I got serious.
