Fabri-cobbling a Autocross Chevelle

[416velle]

Hello all, this is the first post regarding my pride and joy, my 1969 Chevelle that I'm building for autocross! I'm pretty close to driving the thing out of the garage (first time in 3 years), basically axles/differential/fully finishing rear suspension, and some other odds and ends.
To address the elephant in the room, yes this car does have a homebuilt 3 link! I'm in the final stages of mock-up testing and finish-welding it, so I figure now is the perfect time to detail my reasoning and thought process behind some of this along with my goals. Also I just like to build stuff :D

The basics of the setup:
69 Chevelle Malibu
Engine/Trans
-Mildly wild stroker LS3 (13:1 compression, Wiseco/K1 bottom end, ported/milled LS3 heads, ported/rodmod LS3 intake, ported TB, decent size cam), running on corn, brain dyno says 680hp all day.
-F-body T56 (bronze shift fork bushings, serviced synchros, not magnum-ed so I have to go easy on it), Spec 2 disc clutch, American Powertrain hydraulics kit
Front Suspension
-UMI Upper arms, QA1 lowers, Speedtech ATS spindles, ABC Performance sway bar, ridetech TQ Triple adjustable coilovers, Wilwood 14" 6 piston Aero6 brakes.
Chassis
-Factory Chevelle frame with a HPI Customs Frame Brace kit, Fabricated rear control arm crossmember, 5 added bodymounts



Now, the interesting stuff!
Rear Suspension
-Quick Performance 9", Millerbuilt Floater kit, UMI Lower arms, ridetech TQ Coilovers, Wilwood 4 piston FNSL brakes, Fabricated Upper Link and Panhard Bar!

My goals with the 3 link was to address the shortcomings of the triangulated 4 link and allow me to go a little faster in the turns. I'll detail those in specific post shortly.
