Once my motor is back together and in Im going to get new gears. My motor is a basic fun street motor and it has a 262 cam with 460/470 lift and 218/224 duration at .050. im also going to run a stock to mild converter. The gears in it now are stock 2:73's with a rgular 8.2 10 bolt. What are my gear options and what do you recommed i use. The car will be a weekend type carfor fn and car shows. It will see some highway.

I'm guessing you're running a TH350 transmission with nearly stock tire sizes. Of course it's a wild guess, since I have no other data to go on.

I'd say to go with the mild performance converter ~2000 advertised stall speed and 3.55 gears. You'll need the extra stall speed on your converter to compensate for your cam. I know it's probably advertised as the hottest cam you can use with a stock converter, but Chevelles are heavy cars and a little higher stall speed helps.

Of course, everyone is different. 3.73 gears will give you a bit more punch, but higher engine speed while cruising the highway. 4.11 gears are an absolute blast for driving around town, but aren't much good for highway cruising (although I've cruised the highways quite a bit with 'em in the past). People will definitely turn to look at you if you cruise the highway with 4.11's.

I highly recommend using a calculator to see what your RPM will be at a given speed. I use the one at Randy's. It should give you a better idea of what you're looking at.

My tranny is a TH400. They told me I could go up in stall to a 2000 but I just dont want the car to feel like its slipping at all. I want instant acceleration.The tires Im running are 255's. Do you still suggest more stall? The motor is going in next week.
