just one problem after another... someday It'll be perfect...
so I really don't know but I'm having high RPM vibrations mostly +4000rpm to where it really shakes the car bad. I don't like this. IMO, using the butt-o-meter, the vibration is getting worse over time... so I've been taking it easy as a precaution.
what has recently changed:
from 4cyl t-5 to v8 t-5
new ring gear
350cfm holley direct mount
new lifters (installed 1 month ago, ran 2 days then sat for 3 weeks before being ran again)
HID head lights (halogen just wasn't bright enough)
I have a few idea's of why it's bad, just havn't had time to check yet...
Timing, wrong timing can cause alot!!! don't i know it.
fouled plugs, too big of carb? misfire'n w/load +4000rpm???
lifters? because they sat for 3 weeks, or I didn't break them in properly (I just drove the car)
imballance in 3-finger pressure plate (4months ago I broke a clutch and the center grinded area's of the PP, 1/4 inch in, this could be an imbalance and as a precaustion I ordered a new diaphram PP to get rid of it just in case, it just came in today)
guide bearing came out? I made it really stuck in, so I hope not
ring gear made flywheel imbalanced, if so I'll take it down and resurface/rebalance it and install the new PP
imbalanced t-5 trans? (can one be rotationally imbalanced?)
these are all I can think about, I didn't have vibration earlier so it must be something related to what I have changed... Any other insights of what might cause vibration please let me know, I wanna go re-dyno with confidence. I'll be checking the timing and plugs tonight as it's quick and easy.
Thanks

I feel like I'm very close, it's nice to have car back on the road and if I can pin-point it I might stay on the road or only be down for 1 day.
