I have the old 98Cobra S/C 406 in the car for some new testing of a set of Dart 215's I ported over the winter. Engine sounds real good except for a couple of oil leaks it ready to go. Will be interesting to see if it's much better than last years Vortec 406 with the tiny heads that ran 10.90's.

The car blistered the track with 10.60's and 70's yesterday. Need to do some suspension stuff and add my 4.88's to get this thing banging in the 10.30s now. Old engine and new heads really made for a great day, My NHRA friend couldn't keep up lol.
