Question Target Master 350

Hey Guys,
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!

Jay

most of what you heard of them is true, only there made in Mexico, and made poorly at that, most avoid them because there known to be crack prone. However, they are decent engines, and you can add a small RV cam and aftermarket dual plane intake, and a set of headers and low restriction dual exhaust, it`ll really kick up the low end torque, which is what your application needs.

Well i dont like the sound of the mill being crack prone...shouldn't the higher nickel content make the block stronger?

I don't know what double vision is talking about god alot of wives tails get passed along here. Target master 350 are indead made in mexica but the casting are no more crack prone than any 350 block and much better than all except for the early ones which might be equal there is a little more casting flash on them but besides that they have very very good quality and make very reliable engines.

I can see the previous poster has not had a lot of experience with Targetmaster motors, the quality of the mexican blocks is terrible, the machine work is just bad, the castings have production problems, porosity, dirt, inclusions. We have had to return several.

I have one and everything is machined to spec. There sure seems to be alot of mixed opinions about targetmaster engines, but, they all always seem to be just rumors...

Read that article, it will give you an idea of what type of power you can pump out of the engine.

I consider a "wives tale" to be auto tranny fluid with gasoline will make it get better mileage. my information came from personal experience as well as Hot Rod, and popular Hot Rodding magazine. while it is true some have good experiences with these engines, it`s also true that some do not, and in my case the bad have out numbered the good. but as on all small blocks I get, I say the same thing, run`em, and whatever happens happens, if it`s gonna crack, it`s gonna, I got 3 cracked in the bore laying behind the shop.

I appoligize for being agressive there and I"m sure you do have a point but I guess its like everything there are some good some bad I guess it comes down to weather you trust an engine builder to do a better job than the target master would be.

Cool

You have to pour in a little Tequilla. That's the problem with the blocks cracking. They dry out....

Well i got the truck tonight and the 350 works like a top, and has quite respectable power, sounds like it has some what of a cam. Sorry for starting all the controversy. I'll run er' till' she blows!

I've had a few. Out of the three I had the pistons looked horrible. No failure in the pistons. They were just poor looking! Only problem was the valve guides going after 30,000 miles!
I am turning one into a 383. The block has good bores, clean casting and very little core shift!

When I was a kid (17) I worked at a auto machine shop, I was the grunt that tore down the engines to be rebuilt.

I saw a lot of Target master engines, Most had the problems everyone is talking about, But that was before the crate motors were so popular. Now I think they tend to have better quality due to the popularity of crate engines.

GM is really pushing their engines and I don't think they would want anything out there but a quality product.

just my 2 cents!!!

Target master???Is that the same as the stock replacement goodwrench motor??If so I thought the goodwrench motor was just a factory replacement for most stock 80-85 low compression 350s???
