Rear Gear Question

[5389stk]

njk 4.88 or 5.13 converter is close; try stock gears in trans.More power always helps. test,test

I agree with the testing but Milan Dragway is an hour and fifteen minutes away. Wish the old Detroit Dragway was still there that was a 1/2 hour drive.

Nelson, I started reading this and realized this my old car. I would like to save you some money, don't try 513 gear, it lost ET. I assume that you are still running the motors that I had built from Parson/Meyers, I would start with valve springs and more valve spring pressure. Valves spring pressure is the key to horsepower for stockers and as you know I spent a lot of money on that car learning. Hope this helps

Dave, I am not going to go to a 5:13 gear. We still have the 4:56 gear that you had in it. However, my brother talked to Bruce and he said the car should be going through the lights at 6400 rpm and it isn't. We were thinking on going to a 4:88 to get the car off center faster and increase the trap rpm as Bruce suggested..

Nelson: Just my opinion and you've been given plenty, but converter seems too tight, maybe 200-300 looser. I'm not sure what circumference tires you have, but they can be used to "tweak" the RPM's a bit, particularly when you're using a 2.75 trans. Don't forget that the wider gearing of the trans. makes the RPM's fall down more on the gear change. If you're running a 94" tire, a 92" tire will help get the RPM's up. A looser converter will help as well on the gear change.
