LT1 throttle body arm ratio's
You guys ever notice the throttle arm on the y-body vs f-body has a different ratio?
I measured it, and the vette has about 1" of travel, vs almost 2" for the fbody version.
I'm guessing that translates to more aggressive throttle response on the vette?

Re: LT1 throttle body arm ratio's
I have noticed a difference in the arm as well. Having a 370 -410 rear gear makes that short travel lever respond almost too quickly causing a speed surging when using cruise control..

I suspect they didn't want to increase the Dana36 beyond 3.07 to avoid breaking the case.
