Getting the car to launch better WILL help the ETs, but based on MPH and weight of car, it is down on power a good bit from where it should be. That isn't the launch.

I agree thats its just down on power some. I use SS springs and the longer Mp shocks and I only run an 850 DP. I do have more cubes but my car is heavier and I run through a full exh. My 60's average in the low 1.50's with a best of 1.50 and I do not use the pinion snubber as it did not help any with the SS springs. I would work on the tune with the combo. I kinda feel the Victor may be a bit much for that combo also. Myself I run the Indy dual plane and thats with 4.30's and a 30 x 9 tire. Good luck with that nice Coronet. Ron

Whats the timing set to.. it could be way down and
that will kill power... my timing slipped after a
couple of runs.. that was after I checked the timing
but I didnt get the hold down tight and it moved..
I thought I had hurt the engine being that it layed
over that much

Let me build you a 1050 dommy.......

Timing is between 14-16 initial and 36 all in by 2500.

As for the superstock springs I didn't take any clamps off, they are on the car just the way they came brand new from Mancini.

The next day I get some time I'll run a compression test and pull the valve covers to check the rockers/lash.

It definitely doesn't seem to have the power like it did after I first got it broken in. Maybe the basic check over will turn something up
