Go to www.yblocksforever.com for info on Yblocks, of which your 292 is. As far a s the supercharger, they were not 312 specific and would fit any YBlock.

Pertronix makes a unit for your car. If your not rebuilding the engine and its pretty much stock, the stock exhaust manifolds work good.

The 57 4 bbl manifold had a "B" after the number and is a good one for a stock motor. As far as carbs go, anything from Holley, Edelbrock or the 4100 would be good.
