Help with 340 compression + cam change

Working with 650 AVS2, set idle by vacuum (and A/F meter), needed 3 steps fatter in secondaries and silver (strongest) springs for rods. WOT A/F in mid 11’s, and motors seems happy. Still don’t have low rpm oomph I had with 750 but I had .043 pump nozzles in it so this may need more than stock .031’s.

Haven’t set a date to tear it down. Maybe a couple of weeks. I will ask Mike Jones about the .904 lifter grinds. Looking at a couple of Howard’s cams too, but need to check things first.
