Re: making power on 4.3
Yes, except he said his new motor is vortec.
From wikipedia:
4300
The Vortec 4300 is a 90? V6 truck engine, replacing the Chevrolet 250 in light trucks and 200 cu in (3.3 L) and 229 cu in (3.8 L) 90-degree V6s in passenger cars. The 4300 is based on the 350 cu in (5.7 L) Chevrolet small-block V8, and first appeared in 1985 with the throttle-body injected LB4 in passenger cars; light trucks and vans used Quadrajet carburetors for 1985. In 1991, the limited-edition GMC Syclone featured a 280 hp (210 kW) and 350 lb?ft (475 N?m) turbocharged and intercooled LB4 with the first use of multi-point fuel injection on a Vortec V6. The central-port injected L35 (Vin 'W') debuted in 1992; the cylinder block was slightly changed, a balance shaft was added to remove minor vibrations, and better breathing yielded 200 horsepower (150 kW). Another CPI engine, the LF6, joined in 1996 with the introduction of Vortec cylinder heads, while the LB4 was retired after 1998. In 2002, GM introduced a new multi-point injected LU3 engine, and a LG3 variant appeared soon after. This engine's origins date back to 1955, when the original Chevy small-block V-8 was introduced.
All Vortec 4300s use a cast iron block and heads and 4 in (101.60 mm) bore and 3.48 in (88.39 mm) stroke, both of which are the same as a 350, which gives them a displacement of 262.39 cubic inches (4,299.8 cc). Connecting rods still measure 5.7 in (144.78 mm) although the rod journal diameter is 2.25 in (57.15 mm). 1992 and later cylinder blocks used a different timing cover since these engines used a balance shaft (some 1992 production cylinder blocks for the LB4 with TBI induction used the 'traditional' front timing chain cover from the small block Chevrolet). They are OHV engines with two valves per cylinder and are produced in Tonawanda, New York and Romulus, Michigan. Power output of the new LU3/LG3 engines is 180 hp (130 kW) to 200 hp (150 kW) and 245 lb?ft (332 N?m) to 260 lb?ft (353 N?m).

I don't see ANY cars in this list...
Yes, it was introduced in 1985 and was used in some cars, but once they switched to vortec heads (1996) it was only used in trucks.
Even though truck people called that engine the vortec for many years, us marine people only refer to the engines with true "vortec" heads vortec's.
Oh.. and here's the wiki for the camero:

So again, going back to what I said, ANY true "vortec" 4.3 he's going to get his hands on is going to be camed very very close to the marine cam, and it would NOT be the cause of him not being able to get full RPMS.
Going from a 4bbl to a 2bbl on the other hand....
Oh and I've been running fresh water trough my automotive water pump and my automotive heads gaskets for 3 seasons now, with no problems. I don't go in salt water, just fresh lakes. If I wanted to take my automotive motor in salt water, I would install a heat exchanger, rather than pull my heads and change out my gaskets.
Yes, except he said his new motor is vortec.

Now if only he can get it set up right without blowing it
