my yellow dart had a MP short block (came with the 508 purple came) with eddy heads, eddy RPM intake 750 dp, 904 with 9.5" converter and a 3.91 geared 8 3/4 rear.. car would run a consistent 12.20's. best run was a 12.17. i'm sure if i was serious about it and really tried to tune it for the track i could have squeezed a bit more from it.. if i remember correctly the math said it made about 350hp at the rear wheels..
