That video was great! Taking a kid for a ride in a hot car will leave them with a lasting impression for life!
Regarding Mr Porter, I tried but was unable to pin him down on any specific cam. He kept steering me towards tuning the ignition curve. He also suggested to zero deck the block and have the pistons modified by milling a .040 step on the valve side. Great idea, but I don't want to pull the engine right now.
RustyRatRod actually suggested a Lunati Solid flat tappet Part# 30210912 called the 316/326. It specs out at 261/271 @ .050, 540/563 lift minus a .020 lash. My 1.6 rockers take it to a net lift of 554/578. It looks pretty rowdy. I called Lunati and their guy seemed to think it would be too much. I mentioned that it was for a 500 inch (493, close enough) engine but he had no comment about the fact that a 500 inch engine needs more cam than a 383-440. What is the downside of a cam this big in a 493 engine? I lose a bit of bottom end?
Again, that video was great. Your screen name is appropriate!
