496 HO cam

[baja2422003]

Does anybody know the cam spec. on the 496HO? I have a Crane cam that is their equal to the 496 HO, but I would like to confirm. I'm upgrading my Mag to a HO.

I know the lift comes out to .510 at the valve. This is per the merc manual. It doesn't list the duration, though.

That's all I was able to find in the manual too.

Check the 4/7 swap on the Crane

I'll have to look, but I don't think that applies to Gen-VIIs. Plus, one would have to reprogram the DIS so that the coils fired in a new order.
I just looked in the manual and the firing order is 1-8-7-2-6-5-4-3

The OE 496 has the 'firing order swap' already. In fact, I believe you can use the 496 type cams in the GEn VI 454/502's to change their firing order. Crane talks about this in their newsletters and etc.
