I am trying to find a good size cam for my 69. It has a 77 TA 400 with a set of 69 350 heads. I am not sure of the specs for the cam that is in it but it is way too much for the car. It has a Muncie 4 speed with a 355 rear. This car has not bottom end, the cam doesn't kick in until about 3500 RPM, and barely holds an idle. Anybody know of a good cam size that will give a bit of a lumpy idle but good lower end and streetable?
