I had solid lifter cams in both a 390 and the 427. The FE Ford motors have shaft mounted rocker arms, so the adjustment screw is on the end of the rocker (not in the middle), so they are a real PITA to adjust (with the car running and oil spurting). (The 427 was a 66 Holman + Moody side oiler block with cross bolted mains), so you had to run a solid cam in it (all the oil went to the bearings).even more work if you were running a solid cam. 500 mile valve adjustments if you were lucky. I still have a fe360 in my 73 high boy. Good engine. Leaks like a sieve. I've been blessed to be brought up around 60-70s vehicles. Actually I was the first to modernize when I got my 93 f150. Before that I drove a 75 f250 360 points ignition. Actually hated that truck. C6, full time 4x4, gas hog.
The first things my brother and I usually did was replace the points and condenser with a Mallory Photocell Electronic ignition. They were easy to install and worked really well. We also would replace the stock timing chain with TRW double roller, just to make sure everything stayed in sync.
