m6 3:42 vrs auto 3:73 3800 stall
I'm thinking of getting a 97 lt1 auto (hi-performance build) with 3:73 gears and 3800 stall converter. I now drive a 97 lt1 m6 with 3:42 gears (20cty/27hwy mpg), and prior to that drove a stock 97 lt1 auto with 2:73 gears (19cty/26hwy mpg).
What differences, or concerns, should I have about the new car. The mods have been on it for over 3 years, but it's only driven about 10 miles per day. I know that it will need a tranny cooler.
Areas of concern include maintenance, mileage, durability and any insights I can be given.
My cars are street driven for pleasure only, although I do enjoy power and great acceleration. I may want to take a 1000 mile trip through the mountains, or 500 mile trip to the beach sometime.
Thanks,
David

With a 3800 stall, the car should have had a cooler on it already without a doubt...
The converter car is going to feel WAY different. If you've never driven one before, it's going to feel like driving a badly slipping tranny at any rpm under stall speed. the first time you stand on it and haze the tires from a second gear roll though, i think you'll be as hooked as the rest of us. 3800 is relatively high, though for a pleasure car, you probably won't mind it much. my converter is a 3800 and with 3.42s it feels a little sluggish driving around in traffic but becomes an absolute animal when you open it up on an on-ramp.
. yours will get up and go a little quicker around town with the LT1 torque curve and the lower gears out back.
you get used to driving a high stall pretty quickly. as long as you have a lock-up converter (which im sure you do) a 1000 mile highway trip should be problem free as long as the car is in good working order. you might want to hook up a trans. temp gauge just to keep an eye on the fluid temp. it's probably the first gauge i would ALWAYS install in a stalled auto car.
id suspect you'll probably see around 16 mpg city and 20-21 or so on the highway. i get 17/24 with my 3.42s though i've heard the LS1 is a bit more fuel efficient than the LT1. in any case, if it runs right, it shouldn't be a pig on gas or anything.
