Targetmaster and Goodwrench are the same thing, as far as I know. It seems targetmaster is american, and goodwrench is canadian ? Maybe someone else can make that more clear.

They also have 8.5:1 compression, and heres a wonderful picture of how they come out of the crate, yay!

I am wondering if the Target Master 350's are decent motors. I am buying a 1979 3/4 ton Chev 4X4 to use as a plow truck and it has the 350 Target Master under the hood. I have heard that these motors have 4 bolt mains, high nickel content blocks and two piece rear seals, is there anything else different about these motors than a normal 350? What kind of HP would this rig have and how is it easily improved? Headers must help quite a bit, and cams and domes right? I dont need a high HP motor for this application, im just wonderin' if its a decent motor. Thanks for any input you might have!

Well you need an engine that takes high and sustained loads that's a tough a bill as a high speed racing engine, not that you need the high speed but you need a stout bottom end.

Headers are not that helpful unless you're operating the engine in an RPM band where you get the tuning function that helps fill the cylinders. That's an iffy place that comes and goes with engine speed and the total lenght of the exhaust system or at least where there is a collector box big enough to make the pulses react as if they hit the atmosphere.

There really ins't anything different about these motors than a regular truck 350 of pre swirl port heads (1987 thru 1995).

Chevy High Performance took one (bottom line version) and built it up over several months and issues to where the stock bottom end with a Comp XE288H cam, Edlebrock RPM intake, Holley 750 CFM carb and finally AFR heads and 1.6 rockers and got well over 400 horses from it and through all those dyno pulls it stayed together with the cast crank with factory rods and pistons.
