I don't know it but someone with a 6.2 should be able to find out for the advertised duration at .050 and lift are usually in the engine owner's handbook.

 

CFM ,thanks for the reply . I searched the net all over
the world .No info on this special profiled roller
camshaft ,owners manual included . Maybe I just
take one of the engines apart, and measure the damn
thing. :laugh:

 

Your from Canada - probably long time 'till you hit the water - you have time :bigsmile: :bigsmile:

 

CFM, we have mild winters here . I'll go boating
anytime :laugher:

 

Mirage,
The cam Is:
270*/276* adv
214*/220* @ .050
.452"/.465" valve
107* ICL
112* LSA

Bob , the lift on the cam spec you sent me indicates
1.5 rocker ratio. Merc's 5.7 has a 1.6 .Do you know what is
the rocker ratio on the 6.2 ? I'll pick some brains at the
upcoming boatshow here.

 

Mirage
The standard 5.7 rocker ratio rates at 1.5 and measures somewhat less at the valve.
Bob

 

The scorpion has 1.6 ratio I think. Friend of mine is a
merc rep ,he'll try to get me the info later. Thanks Bob

 

Mirage,
Were you looking for the Scorpion 377 HP cam specs or the 6.2 MPI? They are two different animals.
Bob

 

Wasn't Lingenfelter the designer for the Scorpion? Or was it just the intake? Actually, if he designed the inake then he must have had say for the cam as well.

 

Scott,
The Scorpion cam is a Crane piece. I don't know if John did the cam, but if he did, Mercruiser is the benefactor of a great engine man. He is missed.
Bob

 

That's for sure! Was/is a big bummer but it happened during what he liked best.

He did a ton of R&D on the TPI motors, which this cam is designed for so it wouldn't suprise me.

 

Bob I have the 6.2 MX not the scorpion. Just wonder
how much diff on the two camshafts.I know the mx has
hypereutectic pistons [prefer forged] . The scorpion
was a better engine ,but way more money for only a
few more horses. The link you sent me states crane
cam . Is it for sure ? Boating magazine had a good
write up on the mx ,but no specs for the cam
either :

 

Mirage,
Yes, Crane make many of the cams for Mercury Marine.

 

I assume the MX 377 has a 1.6 ratio . The cam info
you've supplied would work out to a 481 / 496 lift .

 

Mirage,
Those specs are @ 1.5 rocker

 

I know that this is an ancient thread but there is 0 info out there about this cam.

I have one marked 6492 on the end that was pulled from a 2008 350 Mag MPI engine. It measures .450 (maybe .452) intake and .465 exhaust @1.5. Lobes measured .3 and .31

2 people at Crane told me that they did not grind this cam and said there would be more numbers on it if they did.
