The car is a '70 Nova, 355 SBC, 700r4 tranny, stock driveshaft cut down and balanced over two year ago, 8.5" posi rear w/3.42 gears installed last year. I have noticed that for quite a while, I get a vibration at about 1,800 rpm thru about 2,100 rpms and it seems to be getting worse, or I might just be noticing more! The vibration seems to not be near as bad when the drivetrain is under load ie. when accelerating normally. Under light load or cruising seems to be the worse. Also, it is not a steady vibration, but more of a rhythmic vibration that pulses about 1/2 to 1 sec on then about 1/2 sec off. It also does it in any gear, although first gear is not to tell since it shifts pretty fast!
At first I was thinking tranny, but now I'm not sure how to tell...
If anyone has a guess, I'd love to hear suggestions!
Thanks,
Bill C.
