Lenny built it for the 408 initally, when I built the 434 I talked to Lenny after it was on the dyno and he told me to run it as it should be close. It didn't work, the 60' was way off and it was slipping on the big end. It was sent back to Lenny and gone and configured for the 434. It still didn't work, that's when I sent it to Kenny Ford at PTC.
