66 GTO

I have a 66 GTO Sedan body. I am doing a frame off resto but not worried so much about original. I would like opinions as to what would be the best route for the suspension system. I would like for it to ride a little lower than stock. I would also appreciate any ideas on which front disc brake conversion system to use, along with what size tires would be best.I think it origially came with 14" tires. Any thoughts on the engine to use would be appreciated. All I have is a couple of 326 Pontiac engines, and a 400 in a 76 Trans Am all stock.

if u would like a mate I have 1966 convertible #matching engine&trans needs your help_ i am selling it craigs list atlata or email me 4 info
