I have an 86 el camino with a 305 standard engine
my transmission is going out and i would like some advice on what the best
kind of transmission to put in it i want more power than the last one?
More power, that's the engines job. But the transmission gets the power to the road. You probably want to put in a higher stall speed convertor to get the RPM's in the proper range, and adjustments to the Valve body. Work with a local performance transmission rebuilder on some recommendations and a rebuild.
B&M, TCI, PA etc... check online.
