Hi guys, had another date with the dyno yesterday. This was an old school 496 built by MM in 1993. Ultradyne .613, stage II ported 906's, 10 to 1 comp, welded crank, stock rods. I had it in my car then sold it to my buddy, he put a six pack on it and wanted it dyno tuned and wanted to know what power was for kicks. So off to the dyno we went. First 15 pulls were to get jetting dialed in, then another 15 pulls messing around with timing. It liked 35 best which surprised me, I thought it would like 38ish with open chambered heads, but not so. I will also post a couple more dyno sheets of motors that I have built, these were all on the same dyno.
