I bought one around 2006. Installed the locking collar on the shaft and recurved it to be all in by 2500. Along with an MSD 6AL it’s been flawless for 15 years in 70 440 Cuda.
Can I ask what your rear gear ratio is? Also stall speed if you are running an auto. Thanks
3.55 4 speed, 28 inch tire (275/60/15). And I run the vacuum advance at about 54 total. 34-36 on the mechanical.
That’s about where I’d like to hit, I have 3.91s with a 3,000 stall converter and 255/60s. With the converter I might have to push closer to 3k, have read some posts saying that the Mallory units keep advancing up to 4K and that the spring kits are counterintuitive. I will have to play around a bit.
