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.
