I just got a bit muddled up with Scottys and Coopers and in my excitement showed my average computer skills when quoting on here.

I have the LT4 Hot Cam in the LT1 in my 65 Impala. It's still pretty tame with that cam. The 2k rpm stall and lockup works great with it. I honestly would want more if it wasn't a top down cruiser.
I'm running a 4L60E and I probably put 30 tunes into the computer just adjusting the lockup and shift points when I first got the swap done. Honestly, if you don't have the trans yet, spend the extra and run a 4L60E with a stand-alone computer which monitors both road speed and engine load (or throttle position). You will not regret it.

Sorry Cooper, I meant to quote Scottyp99 and his link to the other site where a Torrington bearing got crushed when a motor got dropped or hit and it shows the damage that occurred.

Yeah, I just posted that link to make sure I knew what a torrington bearing was, had nothing to do with 'vettes, I think it was a rotary engine, wasn't it? Hmmmm...........a rotary engine in a 'vette.........awwww, man!! Now you guys got me thinking about stuff!!! Stuff I can't afford to even be thinking about!!

Turning the wheels it's between 3 and 3.5 revolutions of the pinion so from the option info I found it seems 3.31 is the ratio. A little higher than your ratio but a little heavier car. Actually, it's maybe only about 120lbs heavier based on the info I found.
As I already posted, I dialed in the gear and lockup for the different speeds to make it nice and driveable without any lugging or higher rpm's then necessary.

My 'vette is around 3240 lbs. with a full tank of gas, eventual goal is to get it down under 3100, maybe 3000 someday. Still, that is something for me to think about, thanks, man.

Weight cutting or the '80 is lighter than other year C3 because I saw a few numbers for C3's around 3500lbs?
I looked again and found another '80 weight, 3206lbs as the shipping weight.
The Impala is supposed to be around 3600lbs.
