Where would you have me start to rule out a balancing issue?
I’ve wondered the same thing in the past but like I said I’ve looked at the converter and the flex plate and have compared them to other Weighted magnum flex plates and my converter looks identical to the magnum weighted converter right down to what the weight looks like and where it is on the converter.
It’s easy to see it’s a standard La small block flex plate.
Then the front like I said still has the balancer that came with the crate engine from mopar.
And if it was a balance issue why am I not feeling anything below 2500 rpm?
Wouldn’t I be feeling it all the time.
This just has me baffled.
