mx 6.2 question
 

Does anyone know the camshaft specs on a stock merc mx 6.2 particular duration?

Crane 104224
 

Don't know for sure, but I read on here a while back that the cam in the 6.2 is a Crane 104224. See link for specs.

You planning more than exhaust and shorty?

Making sure things are gonna work. There might be a problem with the amount of duration with the cam causing reversion. If so might have to go a different route!

thanks 4mulafastech.

From Merc Service manual 24 supplement:
Engine 377 CID (6.2L)
Lifter Type Roller Hydraulic
Rocker Arm Ratio 1.50 to 1
Valve Lift
Intake 0.3114-.3153 (.79-.80)
Exhaust 0.3160-.3200 (.80-.81)
No duration spec.


From Merc Racing Service Manual 7:
Engine 377 CID (6.2L)
Lifter Type Roller Hydraulic
Rocker Arm Ratio 1.50 to 1
Valve Lift
Intake 0.510 (12.95)
Exhaust 0.530 (13.46)

Lobe lift +- 0.002 (0.051) I= 0.340 (8.636) E=0.3534 (8.9763)
Dur @ 0.050 I=222 E=230

It is good to look at that. What exhanst are you considering?

Really need the duration @ .050, stainless marine short risers to work with the corsa Q&Q. I think the merc racing specs are for the scorpin I'm needing specs on the regular black mx 6.2

That 2nd one is for a Black Scorpion. I recheckd another service manual, but still no duration specs listed. I was actually surprised it was in the one for the Black Scorpion.

John S thanks for looking, they probably have yet a different one yet in the blue scorpion.
