Friends, lovers, Chevy cretins....Let's unf*ck a Six Pack

Thanks! If you plan on factory air conditioning I don’t think the factory air cleaner will fit, but probably easy to mod. Besides, I’d go with a modern compressor anyway…..
This car has ZERO options on it other than automatic transmission and possibly power steering, both of which I hope to keep with the 440, even though I don't know how ps works on 440 A bodies.

I'd like overdrive on the car and since it's a 4 door with no slicks or drag racing, I'm considering how to go about adding a A-518 to this project while still looking 'factory'.

I may just keep the 3 speed automatic. What did the six pack cars have for kick down linkage and how close is that to the 4bbl linkage?
