I agree with Rog. I am running a 686. It was not done by one of the big name shops out there, but it can run with them. At the Firebird race Thrashem-Crashem was pulling me on the top end in the straights and a little out of the hole. Maybe some of it was clutch tuning. It was my first race with a dry clutch. I know he runs a big stroker, not sure what exactly. At the last Page race we were turning damn near identical lap times. I changed my clutch tuning for that race. Granted there are other factors at play. I got a PM from bobby and sounds like he will be coming out to the Whiplash race this weekend at Ft. Mcdowell so I will have more data for comparison. It's a long race so there is plenty of oportunity for us to be side by side plus the lap time comparison.
