High Compression 390

I spoke to Racer Brown about a cam today. Jim also agreed that with the right quench, 11.25:1 wouldn’t be a problem. He is going to think about a cam with the right amount of lift and duration for the altitude.

Nice, I think I'll call him for my cam too, that's reassuring he says it will work. I wouldn't be surprised if the quench was off the mark in my past build, I used .039" head gaskets but didn't go through the full process of making sure each piston came up to zero deck. I only measured #1 and it was still .003-.005" below, the rest may have been more or less as my machinist said the block had already been decked but not square-decked. Also I later checked the accuracy of my Harbor Freight compression tester with my air compressor and it was definitely reading low by maybe 20 psi at 150 on the compressor gauge so I think the actual compression was higher. @nm9stheham the Voodoo cam I had not only has 'fast' ramps but is ground 4 degrees advanced from the factory and is advertised as being intended for smaller-displacement engines with stock/lower compression. I first bought the cam for the stock 318 the car came with, I was dumb and wanted to save a couple hundred bucks so I reused it (with lifters of course) in the 360. Sure had a sh**load of torque on the bottom end at least and it lasted maybe 20k miles even with all the pinging.
