Vibration ONLY at 75 mph
BTW even though im sure that slant runs (driveability wise) like a mild build, you amuse me with your definitionnof mild lol! I call that moderate.
Lol, well it is mild by my definition. The car does have issues with pinging above 4500-rpm's in 3rd and 4th gear on pump gas with the high rear axle gears but other than that it is insanely drivable. The vacuum is very high at idle (15-inches of Vacuum @750-rpm) with a nice subtle lopey idle. This engine was also in my 66' Dart with a pro shifted four speed, and a 4.56 gear spool and ran mid 13's in the quarter. In this green street car, best run is a 15-ohh with 3.23's and street tires. Compared to my previously installed 360 in my 66', this slant feels like a dog. (V8 spoiled me)I even have a 60' Corvair with a "mild engine" and a stick and it runs similar quarter mile times..
The rear tires have been on the car for the last 30,000 miles of the 40,000 traveled in this car, and they are wearing more in the center (burnouts + high air pressure) but the wear is uniform around the tires. The previously used rear tires for the first 10,000 miles got used up quick doing some street racing/burnouts and the early drag racing action. And the first pair of tires wore evenly across the tread with out any signs of a toe in, toe out/ camber alignment issue. Since the car got all of its drivetrain stuff swapped out, I've been nicer to it, (no more drag racing) and have been primarily driving it like a grandma. lol
I'm stumped too, hoping someone on here might aid in some insight. Next I'm going to accurately double check the wheel base from side to side as that is something I haven't done. The front aligned beautifully, and it steers perfectly straight at any speeds even with the brakes heavily applied so i doubt even if the wheel base was off a little bit as it would show up in the alignment or drivablity. Also I should add, that I'm sure this car hasn't been in any kind of accident of any kind, it was a one owner 79,*** mile car when I got it.
