Re: corvette suspension in chevelle
If you're going through all the effort to graft in 'Vette suspension I'd suggest using the C5 or C6 rear suspension rather than the old half-shaft based "twitchy" C4 rear suspension. It's a huge improvement in driveability and predictability over the old C4 setup.
With a C5/C6 setup you could also keep the transaxle & torque tube arrangement for better weight distribution or you can get a 3rd member adapter for the C5/C6 rear diff to keep the transmission in the "normal" location and run a standard driveshaft.
One thing to keep in mind is this: The Vette suspension has the geometry optimized for a vehicle with a lower mass and much lower CG height than our Chevelles so it isn't really an optimal suspension for our cars weight & CG. The higher CG in a Chevelle leads to more body roll and the Vette stuff has a rather low FVSA / camber gain for a Chevelle because the lower CG Vette simply doesn't put as big of a roll moment on the suspension.
FYI, there is already an excellent front suspension setup for these cars from SC&C and there is a forthcoming 3-link for the rear of these cars that will get rid of all the converging 4-link woes when it comes to a handling application.
Old setup: Procharged/intercooled/EFI 353 SBC, TKO, ATS/SPC/Global West suspension, C6 brakes & hydroboost.
In progress: TT LS2, T56 Magnum, watts link, Wilwood Aero6/4 brakes, vaporworx, floater 9" rear, etc.
