63 Nova cause Everyone has an F-Body

[63ImportBeater]

63 nova SS, EFI 383. Current suspension is Global West Multi-Leafs in back, and the front is as trick as can be for a lame stock nova suspension(Boxed A-arms, eccentric lock out, stiff springs and shocks, quick steering box, sway bar and discs but still lame nova geometry). Car will have a 6-speed and be a serious road race piece that will still get considerable drive time.
Could someone recommend where i could get a front subframe that encorporates chevy components and no ford junk. I was also planning on a 3 or 4 link in back till i read everyone here saying leafs are good, and I've seen people praising the trailing arm system from HTH. I am very confident in my fabricating skills but not as much in my knowledge of the capabilities of these differant systems. The front/rear clips will be tied together well with a cage and such. What is the best rear suspension for road racing and where might i find a kit for it? Thanks in advance for any help.
