Stormrider,
Is your engine a Gen IV or Gen V?
GM performance parts has two cams that make more power than the stock cam. And they cost less than $200 for the cam and lifters...
A friend of mine has a 94 454 Mag. We did a quick re-lap of the valves, cam change, and bolted on a new carb. He gained 300-400 rpm with the same prop.
Do a leak down test to determine where you are loosing compression. Maybe you just need to do the top end?

OK guys... my block has gone to the shop. GenIV, rect. ports... the good stuff.
Block is getting bored 30 over, new pistons, roller rockers, valves, cam, intake, carb.
Heads, rods, and crank are in great shape!
Gonna need an exhaust too, either Stainless Marine or Dana.
Gonna take off the drive and have it gone over... it's been at least 5-6 yrs since any work has been done to it.
Should make for an even more fun summer.
It also keeps my mind on the boat during the winter months.
