I used that cam to get the car on the road. I had a set of 3:91s and they were bad once I drove the car, so I installed the factory 3:23s. So now waiting to get the funds to rebuild the pumpkin. Its interesting why so many people say no slappers on Mopars. I have always been told that and I think once mis-information gets out there its like a run away train. Mopar Officials video was very good and made sense. Never seen that before. This is a street car, not for the strip. Yes on the 750 vacuum. Thats the next thing after the gears. The cam is a solid Lunati I bought back in the 80s. 249 @ .050 and 508 lift. 108 LSA 31 degrees overlap. Pulls hard above 3500. Motor has ported X heads and RPM airgap.
