Any Ideas?

Hello,
can anyone tell me what this sticker means? The engine is supposed to be a new marine engine. Does the firing order support this and why is the firing order different on marine type engines.?
Thanks,

reverse rotation?

That's the standard 351 firing order. The 351 and 302 cams interchange, you just have to arrange your dist leads to suit the firing order (cam) that you have.

I'm confused, is this a 351? and not a 302 marine engine?
Doh!!

The 302 motors use a 302 firing order. The 302 HO (High Output) use a 351 windsor cam and the 351 firing order.

So this sounds better, maybe it's a HO?.
I must admit I have tried to make sense of the numbers I can see, but they are not in the identified areas. Looks like I shall have to get my torch, pen and paper and write down all that I can find!!

Better? Yes
The HO normally comes with forged pistons,better heads,double roller timing chain and bigger intake (if it came with one).
