350 magnum upgrades
sorry to beat a dead horse I have an 84 formula 242ls with the twin 350's 260 horse I have looked at tons of threads only to get a little confused I dont have the money to buy 2 built engines but my question is I have read that bolting on some vortec heads would help, is that just regular truck 350 heads or do they have to be marine. I know that I can physically put any 350 chevy cam in it but what kind of cam am I looking for will it say marine cam? Everything that has marine labeled on it doubles in price so what will work? I looked at intakes, do I need dual plane, single plane? the engines have 300 hrs on them so they arent ready for a full rebuild but what ever I buy I want it to be useable on a 383 or whatever I decide on
thanks for any info

steel dart heads 200ccrunner 72cc. open vic jr. intake 750cfm holley, 480, 480 hydraulic cam, and a good set of exhaust used probably 2000 for the exhaust and about the same for the rest if you find some good used take off's and do it yourself . get some cross over too.

For a $7500 boat, I would say leave it alone and go boating. Save the money for your next boat. At most, I would get props lab finished and gain a couple mph.

What Hunster said. I've been down that road with several boats. Save your money until you can get a faster boat. After you've "busted out another thousand" you won't be happy with how small speed increase is versus how much you spent. Just drive it have a beer and a good time.
