The 440 picked up 1.5 MPH over the 383 at the big end. Timing on the 383 was at 40*. The 440 is at 38*. For what the 383 had in and on it, I think it ran pretty darn good. This whole combo, old and new, puts a new meaning to the term budget build.
4 speed street legal. Best time 10.99 @ 124 mph on 93 octane pump gas @ 3926# total weight
