Inching into 12's..... 2.94's vs 3.23's

With a one wheel rear and no tach you are leaving a bunch out there to pick up.

The car sounds good going down the track and tons of fun will be had with it!

Why are you concerned with ET’s and running Open rears with 2.9 and 3.23 gears? Just seeing what’s possible with plain pieces? I’m new to your project so sorry if I missed it of you already stated the goals.
I’d like to add his is working from a minimalist stand point. AKA - Do the best you can with what you got. Then add something to it. Minimally. He works the basics with what the car was born with and moves forward.

He has a channel on YouTube which helps the new guys show what is possible without running out to the store and dropping bucks on parts to get the car running it’s best. It is often what a lot of us forget to do (or mention in threads) is start with the basics. The thing most people don’t do.

Give his channel a look.
