AMC 360 in YJ......Carb & Timing worked out

Well, after several trial, errors and thinking some things out, Im very close to tweaking, if not already there......I hope. So heres the set up: AMC 360 with performer intake, 4160 Holley and HEI ignition. The Holley had to be set up like this: main jets #62, with #31 pump dicharge nozzle. The timing was critical at times and fun to play with matching the ignition but this is where replacing the spring in the mechanical advance made the motor really come alive....Mr. Gasket part number 925D. replaced only

1 spring (left the OEM spring on the other side) and the performance was greatly improved. Now the 360 is performing great..........but will watch it closely to see if this holds........

Just curious: was the new spring a lot weaker than the spring you took out? (This would give you a faster RATE of advance which could improve your low-end torque.) Another trick is to block off part of the total advance slot and then set up the initial timing.
