360 Tuning Help

A starting point for me would be to bring the carb back to the stock jetting. The Eddy kit will show you the stock jetting numbers in the chart with metering rods. a new set of plugs (autolite 65) or Champion rn12yc., and a re-curve of the distributor if it is a stock distributor.
I changed from the Eddy to a Holley 670 street avenger, on my 360 and it was a world of difference and easier for me to tune. I also got rid of the orande box and converted to HEI and I picked up 3mpg over the orange box and it also made it run much smoother.
