I wasn't faulting, I was giving him a heads-up warning. We know how much some Pontiac guys love seeing a Chevy dropped in any Pontiac engine bay. Heck, some will start to gather pitchforks and torches just for using a Camaro spoiler.
Hmmm camaro spoiler.LOL
It'll go good with your Corvette rims.
But seriously (since apparently providing 5 different transmission options is not a serious reply), the Covette rims offsets are way to high, and it can vary a little from car to car, but even getting the backspacing perfect, you'll be lucky to fit a 245 in front and a 275 in the back.
