Small block 360 cam choice
I had that cam in a 340 and the car ran 102ish MPH in 1/4. Another car with the same cam, 360, 1.6 rockers and really good iron heads has run 11.70's.
I had single spring cranes on mine.
Any of the 901 springs will work. Look at 16901-16 trickflow springs. Same as the 901 comp IIRC, less $.
