Ben,
I was typing at the same time as Mark, and he brings up very good points on the relative differences of the Camaro to your new wheelbase, and especially watching the control arm angles. I'm by no means an expert on suspension geometry, but if you've considered ride height in the positioning of your front clip (may need to "Z" your frame connection to keep the suspension zero'd at your ride height) then if you have everything square and level you can center your wheel in your wheelwells and be good to go. You mention "...decent pitch for the drive train...". When you set up your rear suspension you will need to set your pinion angle (uptilt) to match the angle of the engine/tranny to eliminate vibrations. Extend a line from the center of your front u-joint through the center of the rear u-joint, and the included angle of the pinion shaft to that line and the transmission output shaft to that line should be equal and opposite. Here's a link to an Inland Empire explanation of driveline geometry http://www.iedls.com/asp/admin/getFi...&TID=28&FN=PDF Maybe some of the more experienced scratch build suspension guys will jump in here, like Dave or Jerry, or ???
