Welp, my project got sidelined by a move...had to put it together in my kitchen. BUT, I got the compression fixed! I had the block milled another .055" to pop my pistons out .005" and took another .032" for a total of .062" off the head. This gave me roughly 62cc chambers and 9.9:1 compression. I converted from road draft draft PCV and got a jet kit for my carbs...immediately had to jump up 2 jet sizes! Here's a video of me letting it loose on a back road, 2nd gear to 70mph at 6000rpm.
Holds 50lbs oil pressure across the board and runs @ 195°. I ended up with a Davis HEI setup and .050" gapped plugs.
I'm very pleased with it now. I plan to build another 223 sometime soon with the supercharger when my garage is finished. The only thing I did different when reassembling is installing the cam straight up, I am going to remove the timing cover thus summer and bump it +4° like I did before which should gain me some low end and a poppier sound at idle.
