It's losing a boatload of time in the first 60'. 1.9 60's are good for a mid 13's car.
It took 20 posts before anyone pointed out the obvious ?
If there isn't 3 to 4 tenths hiding right there , I'd be amazed.
Given you want to keep street manners , a 3.91 ish gear is the most I'd recommend......unless you want to throw a GV overdrive or similar at it.
But that isn't cheap.
Get the suspension to work and copy as many stock eliminator tricks as you are comfortable with. Understand that there are also compromises that have to be made ............... the best of both worlds is difficult to obtain.
You will lose some handling if you go balls out with the front end in drag race trim. It will still be perfectly drivable , but you will be slicing a bit off each characteristic whichever way you go.
A good converter is as close to a magic wand as I see for your deal....... but once you're optimized there , traction will become more of a problem.
Simply throwing more motor at it isn't the answer , though there are gains to be had. Nothing wrong with your cam. Porting and carb size would be the first areas I'd look at here.
But if you get that car to get out of it's own way at the green , you're now ready to look at the rest of the deal. It is a combination......not one part or area that makes quick cars quick.
