I cant find where is says the magnum was 330 hp. Like someone claims.
My understanding was they were 365 hp

Mercruiser most definitely built a 330HP Alpha Magnum. It quite literally was nothing more then a small head cast internal 330hp 454. Totally weird deal they did only in i think 87 and maybe 88 but it did exist and they were only coupled to an Alpha . . . not sure what Merc was thinking with that move but it did not last long. the Merc Bravo/Mag starting in 88/89 was a 365hp big port forged internal 454 that was actually a hellofa motor 
. . .my 88 Scarab III had Mags and were 365's on Bravos (first year)
