Good cheap 383 builds??

Yeah...what forphorty said about the converter is SPOT ON. especially with a mild build. you really need to be careful not to get too much converter. Heck, for most street builds, the factory high stall is plenty.

A converter is the most important part IMO....

Converter stall on the said 383 is a question of mine. What would it be? Would it depend on the car it came out of?
What would the stall difference be between a regular passenger car and a hi stall in a road runner. (For example)
