Can I hit the 11's? low 12's

Looking at the incrementals, I think the car is running just fine for what it is. 60' matches up well with ET/mph. I don't see any big gains from what you just added (fuel pump, lines, frame connectors), but they will pay off in the long run with other upgrades. It will probably run very close to the same. You will still be in the mid to low 13's at best.

The last run with the 2.1 60' time (spun off the line I assume) also has a better mph on the top end. This is typical when you spin, you normally get a better mph on the top end.

I'm not a big block guy, so I'm not much help on the specifics to make one go faster....but if you are serious about racing it, I would switch to a double pumper carb with no choke (no air horn like a Proform main body).

It should be a pretty good bracket car, all you need is consistency and it looks relativity consistent as is. Good luck, and have fun.
