Gear ratio is likely 2.73 or 2.41. The transmission is a turbo 350 with stock converter.

You can if you want but I would consider something like a Comp Cams 240. Part#61-113-4. Works with all stock springs ect.
At least get a set of new SBC springs put on the head. Only cost about $35 or so. If you really want to run a stock cam use the one for either an Intergrated head or the stock Mercruiser Marine cam. What gear ratio is in the car? What transmission are you planning on using? Jay 6155
