hinds57 Hope you get the ERA car. Now for the fun. You have the motor. How much power?
Let's say 450hp, what trans are you going with? auto,4speed, 5speed, or 6 speed? Once you figure out your trans the rear ratio will take care of itself. You will have a Jag rear. Your ratios 2.88,3.07,3.31,3.54,3.73,3.91,4.09. I run a 3.31 with a 360hp motor, runs 12's in the 1/4 idles at 700 rpm with a glass of water on it and runs on reg gas. What are you going to do with the car? Cruise,roadrace, car shows, or police magnet??
Try and give somemore info and the CC club will give you the best drive train ideas for the car. My thoughts are 5speed with 307s no overdrive. 6speed with 3.31. For your motor build a tork monster. 4speed 3.07 wide ratio trans.Let's get some motor numbers.
