Need quick advice...Did i make the right choice for gears??
Ok after flip flopping about going with an FI setup, i can't swing it right now being jobless and it will have to wait. I'm sticking n/a with a max 150 shot for the few times i expect to see a track. I bought this car which ran a best of 10.84 @ 123, 1.48 short time at 3800 race weight. I'm hoping to get about 200+#'s off the car in the next month, mostly off the nose.
The rest of the setup is in my sig. I chose to stay with the 4.11's that are in the current 9" and go from there for a starting point with the same 28" tires. Will this be too much gear with the 150 shot or not? I've looked at the wallace racing calculator and it says this will get me to 138 at the same 6800 rpm shift point as the previous owner. Do you think this combo will get me above 140? Should i step down to 3.89's?
I want to get this right the first time!

you have to also account from converter slip which will be anywhere between 6-10% usually depending on your converters efficiency, Slicks will also grow up to 1-1.5 inches so that will give you a little room. but you will probably only get to 133-135 with your setup at 6800 if I had to make an educated guess, you can run it to 7000-7100 if needed
