I finally have my 512 low deck in my Super Bee and I have started the tuning process. I've driven it around a little, put about 10 miles on it today without much issue. I'm curious what everyone sets their timing at on their combo? I know big block timing is normally most comfortable around 38 degrees, all in by 2500. I was also talking to someone that said the strokers like a little less timing. So far it hasn't given me the ride I expected out of a 512, so I'm ready to do some experimenting with the timing before I move on to the carb . It was starting hard and dieseling, as well as running hot and not idling. I've got it starting nice, idling well, but it still runs hot. 210 or so.
I'm slowly getting it dialed in, (very slowly) but would like to know what has worked best for others with similar combos. Thanks.
