to confuse things more there was also a 454 Magnum/Alpha package that was actually a low-po cast 330/454 ..
No. The Magnum name was simply a name given to higher hp "black" motors with forged internals such as the 454 Mag compared to the standard 330 hp 454 ect, and are not to be confused with merc racing. The Mag's came as carbed and later as FI engines. For the injected engines, the terms was EFI and later MPI. The EFI was a TBI setup and the MPI of course a Multiport. Nowadays it seems that the name just carries over for the new 8,2's as it did with the 496's from the 502 and 454. My guess is, that it's more of a marketing thing than anyting else, for the high hp black motors. There was certanly nothing "magnum" about the 496's with all the cast internals. The 350 still carries the sticker as well. Maybe someone has a little more insight of the origins of this name?

Hmm, ok. Not doubting your statement here, but just been through all the old catalouges from '88 and on, and I just can't find that one. The 454/330 low hp was in the early 90's and late 80's rated as 300 prop hp and 330 crank. That was called the 7,4L and not Magnum. The one called 454Magnum, had a 4 barrel carb, and was in fx. '96 rated at 350 hp and that has sometimes been called the 330 too, since merc for a short period also posted the prop hp as being 330 hp. The same year, there was indeed a Alpha/7,4LX 330 hp cank-300 prop which is the one normally reffered to, as the 330. The Magnum name is not present anywhere for the 7,4L's and 7,4LX's though. What year was the package made you are speaking of?

I think it was only produced for one year then they went to the Bravo drive. It was a stop gap between the end of the TRS/Big block and the Bravo's. I think the Alpha was a little light duty for the torque of the big block engines.

the Alpha 454 package was called Magnum even though it was a base 330 cast internal engine..
Says Alpha 454 Magnum right on the arrestor
Here is a pic of one,

It's actually getting some work done to it as we speak and the guy who is working on it said I could upgrade my current engine to an HO for about $2000.00. After that I think I'll probably just leave it alone with the exception of little things here and there and just have fun with it for a while.
