OK so we all agree that a set of drop-ins is the way to go so what should the OP expect as far as prices on low hour fresh water carbed 454 and 502 mags, 420's and hp500's and which is the best bang for your buck option

Since every one has decided for the op, i guess that means he has no other options. What if the 3k is the only 3k he intends to throw at motors.What if he is only looking for a little more,and it wouldn't be the first time someone wanted one that sounded better at idle. FWIW i totally agree he could own a better base motor,but he doesn't .

Thank you all for your input. I think this year is going to be spent on some newer stereo equipment.
MOTOR, to answer your question these are all stock 1993 330’s in a 32 fountain fever. Yes I know under powered but the price was right. The boat will do low to mid 60s on flat water and just over 65 in 1’-2’ chop.
It drives me nuts when a Crownline or I hate to say it but a single engine 27’ Baja is staying right there with me.

What a bunch of diks! lol J/K
I'll throw some ideas at ya. Bolt on a pair of 96+ Vortec style heads. This will bump your compression up from 7.9 to 9:1 with the smaller chambers. Get yourself some takeout cams from a 454/502MAG MPI engine, the roller cams. These can be found cheap, and usually guys have good used GM lifters to go with them and a gen vi timing set. Ditch the stock iron intake manifold for an edelbrock performer oval port. Keep the stock carb, it will be fine.
You'll see a noticeable improvement, and it will sound tougher. Bumping the compression, and going to a roller cam, is a nice upgrade. It doesn't have to be an exotic build. Even if you find the vortec heads from a 96-00 454 Truck engine, they should have Inconel valves in them already.
Put a package together like that, and I will bet it will run circles around a stock 365HP "MAG", make better torque, idle better, and no need to spin it past 5000. Which the stock 330 crank/rods will be fine there.

I think the upgrade MildThunder brought up is more along the lines of what the op was asking .I obviously don't know the op's mechanical ability.With some hunting used stuff and providing his own labor he should be able to get his boat in the 70's within his budget ......My Opinion.
