My personel experiences with that cam back in the late 1990s was really bad, I degree it for the shop in the customers 1968 Charger 383 automatic car, that cam wouldn't make enough manifold vacuum idling at a stop light to stop twice, NOT GOOD It had a nasty sounding idle and didn't pull real hard down low or anywhere else I degree it where Mopar advice on that cam back then I think they replace that cam part number with a similar grind several years later to make it better
The shop owner removed it after driving it once and put in a "R.V" cam that would stop it okay.
The 19-year-old owner wrap it around a power pole within 6 weeks of getting it back
I never sold another one of those cam kits, NEVER
