I have a 650 DP on my warmed over 383. I also have a 750 DP which has been rebuilt by the guy who did the 650 DP for me. For some reason my car loves the 650. With the 750, it's harder to start, and just seems "off." Put the 650 back on, and she's ready to burn the tires off.





My car is the same way. She loves her 650. Easy start, better throttle response, and better ET's.
