No. The first two years (?) the rear cam bearing had two oil grooves and I think was a little longer. Than the later years.

Silver Surfer is absolutely correct. It's been so long since I had one I had forgotten about the different oiling setup on the 55 - 57's.

Totally erroneous information. Go back and do some reading on the subject. I suggest Bobtheoilguy.com

The last cam with the narow lsa and relatively low duration will be a thumper and a tq monster, the tame lift is pretty durable too. I've bought that cam after looking through a lot of cams for a very low budget build and for as cheap as it is it is a great cam for a cruise in car, it has that awesome sound and great power for street rpms. The only thing I would consider with it is a 2500 stall, that makes it perfect.

AP72 is correct-a-mundo!...again.
If you want the "chicken-peck'in-corn" sound the Harley Davidson idle.....the sound of the "bad'uns" back in the sixtys.......the sound of the old dirt-track race engines.....go for something with 110LSA OR LESS!! THAT'S what causes the engine to cut-up when it idling! 112LSA isn't what you're after(I think!)
I have a 66 Mustang with a 5.0+030 engine. the cam is 230/236@050 duration ground on a 107LSA. Sounds like the old 427's of the 60's and above 1200RPM will absolutely scare you!(up to about 5500/6000RPM)
Just my thoughts.

well it lives again....

put in the summit k1103 with the fair idle with new lifters too. timing was off and i cooked one of the tubes on the header, but corrected that... run for 20 to 30 min's varying the rev's.. just took it out to a little test run and wow what a difference it made. i always had a little lag at throttle up but no more.. i really like it so far.. put a new timing chain on while it was staring at me... let'n it cool down to change the oil...
fair idle ain't bad, a lot better then the smooth cam.. it's got a light rhythm to it..
