BPE HEI Distributor

On a whim, I changed the dist springs to the lightest ones I had. Changing the HEI springs is a real joy compared to disassembling the Mopar unit! The result with VA disconnected:

16" @ 650
23 @ 1000
26 @ 1500
36 @ 2000 (tops out)

Reconnected MVA and took it for a test drive. The engine really "laided down" upon acceleration. Disconnected the VA unit entirely and that went away. Performance did not decrease with the VA disconnected. No doubt too much timing with the MVA connected. The process continues....
