If its still bone stock just tuning on the dyno may get you that 10 more you need. Port polish head and port matching of the manifold will also help. [Reply]   [No Email]

Unless you are going to run low gear all the time , it will lug down , especially on a good track. [Reply]  [No Email]

Them 4020s were kinda different you had to reset the carb for light and heavy work. Tune it up see what it gets you could also play with the timing and see if that gains you anything.

Would outpull our diesel with both of them wide open. But the gasser had no low end torque. I had the aluminum carb from a G900 Moline. I also had to wrap the manafold right above the carb with 3/8 copper tube hooked to the water-pump. To keep it from icing plum shut. [Reply]  [No Email]
