A Monte is pretty heavy -- even with a 454 makin' goobs of torque. Back in the day we ran a 3:91 and they pulled real well ... TAZ

I know this is splitting hairs, but in a 454 that is an LS6 cam.

3.31s should pull pretty strong with a decent converter in an A-body. 3.73s will feel snappier but you'll hate them on the freeway.

Couldn't agree more. I have 3.31s in my BB 69. Very nice happy medium for the street and highway. I do have an M21 though.

Listen to green LS6!
The corvette passenger side manifold is worth something, or the boys would not have brought it up when I showed up at the race with it on. The drivers side is better, but the passenger could not be any worse

Call ATI converter and tell the tech what your combination is for best converter performance. They are good knowledgeable people. Yes the L78/ LS6 cams are the same. I say go with a 4.10 gear for the street. I use one in my street SB Nova, nice gear.
