Quote: Broke in the 383 cam I got from Mr. Six pack two days ago on the engine stand and put the motor back in the car today.
Let me back up and say that my engine builder came highly recommended and with everything else on the build he did great, but he had his "connection" cam company custom grid a custom cam for my motor and after 100 miles I knew it had to come out. It just wasn't right and wasn't running good. Spoke with Bob (Mr. Six Pack) and had him send me one of his grinds to see if it was better. Let me tell you I could not be any happier! The car runs fantastically and is really responsive. I'm running stock stuff (stock intake, heads, exhaust manifolds, carb) and the car feels so much stronger with Mr. Six Packs grind compared to the grind my engine builder put in. Plus it idles and runs so much better.
I would STRONGLY recommend Bob (Mr. Six Pack) to anyone who is looking for a cam grind.
Has anyone used his 340 six pack grind?
In talking with Bob on the phone, he told me that when his original six-pack cam started going flat (I believe it was sometime in the early 90s), he turned to the major aftermarket cam companies and had a number of custom cam grinds made based on their recommendations. He said none of these custom cam grinds had the snappy feel of the factory original six pack camshaft so that's when he started experimenting with his own cam grinds. He said the first cam grind he tried is pretty close to the one he still uses today. Bob has a whole box of those aftermarket custom grinds sitting in his basement collecting dust, that is unless he's taken them to the recycler since I last spoke to him.
Bob also told me in his down-to-earth non-arrogant way that he's helped guys swap out their MP 484 and 509 purple shafts for his cam grind for a performance feel people find very surprising.
