What work was done to the 750 VS? Does it have the secondary metering plate and you've changed the secondary spring? I don't think a DP will do much for you besides add more levels of compleity and tuning, and kill the street manners in terms of gas mileage. As it sits, the car is IMO still a little slow. Similar builds I know of are 12.8-12.60s all day in the heavier later A's. I think the intake (not the Performer RPM, right?) is holding you back a little. If your ignition is curved well and it doesnt miss, IMO MSD would be more of a luxury than a "magically faster" pill, but I think improvements could be found. 104mph says you should be about .3 faster. What is your 60' time? Do the tires spin at all?

The carb has been jetted the secondary spring has been changed but it has no secondary metering plate.

I think it is capable of 12.8's allday the way it is with the right track conditions.

Intake is just a Eddie Preformer I will be fitting a RPM airgap in the next few weeks.

Ignition was recurved but I forgot to ask them what they did so I will in a few weeks when I get the new manifold on.

Went to the track last night was a mistake was freezing first run 13.08 at 105mph was what I expected as it was only a warm up but next run the sun had gone down & a very very cold wind was blowing & the track lost all it's grip 7 we had wheel spin off the line & for at least 1/2 track so waiting for warmer weather before we head back should only be a few weeks till winter is over & things start to warm up & the days will get longer.

We increased our MPH just by going from 70's to 72 jets so that was a good thing

Our best 60 foot was 1.8 so far

The tryes don't usually spin but last night they did as I said it was very cold even after the runs the tyres still felt like they were just warm.
