Any signs of reversion? I don't want reversion problems but also don't want to spend the $ on a custom grind if I don't have to. I just e-mailed Crockett with my plans and asked for opinion about 112 vs 114 LSA. Appreciate everyone's feedback on AZM

Call Crockett, he answers the phone a lot more often than he answers e-mails...
You will not have reversion issues with a Crane 731 or a Crane/Merc 500EFI cam...
No need to bash AZSpeed, just take our advise and use Crockett...

Thanks, I'll call him. BTW: I didn't bash AZ Speed at all. I just thanked you guys who strongly recommended I use Crockett-

No, I know you didn't...
I could though; but there is just too much of that on these sights...

Aren't they one and the same cam?

Cuda: I've looked a so many cam specs my eyes are going crossed, but I believe there my be a slight, probably insignificant difference between the Crane 731 and the Crane/Merc hp 500 cam

I'm cam shopping also. I asked what cam was used in a 500 EFI, and was told it's a Crane 731.

They are vary close. The lift is the same. In Post #10, I gave you the spec's.
The 500EFI has a 114°LSA and a bit more intake duration.
On an EFI engine, I would use the same one as Merc Racing.
One other thing about the 502Mag vs. the HP500 is the intake valves. The HP500 has 2.25 vs. 2.19...

I know what you mean. My cams were ground on 114* too (or maybe even 115* lobes) and my 565cid NA engines idle like stockers as well and the drivability is incredible. Makes it nice for shifting/manuvering, etc.

Crane has a custom grind # for the Crane 731 except ground @ 114 deg. LSA- #16HR00017. I checked w/ an online dealer called Horsepower Wizard (there's a link on Crane's website)- they quoted me 383.40 for custom grind-
