The fact that is has a four bolt main makes it ''not '' a 327 anyway .
There is no such thing as a 327 four bolt unless some put a 327 or 307 crank in a 350 ; or 302 block with a four bolt main .
If it is a 327 four bolt .. some one MADE it a 327 four bolt .
As for horse power .. I would say 180 is most likely close .

It doesn't have a suffix code because it's a stock replacement crate engine.
The 'M' gives it away. If you look beside the casting number you will see where it says "HENCHO EN MEXICO" which means Made In Mexico by GM of Mexico. These are common and are known by there name of Target Master.
Also you can't throw a couple of performance pieces at a stock engine and it magicly produce 400 horses. If you don't mind me asking what is a Edelbrock dome?

I thought that was a Canadian thingy. LOL
I have heard LOTS of people call an intake ... A DOME :???
Not sure where it came from but I grew up in a scrap yard ...
And lots of people will say they changed from a two barrel dome to a four barrel .
HENCHO EN MEXICO ::: Most likely more like 165 horse

If I recall GM posted the target master 350 would put out 250 horses with a four barrel intake/carb and a set of headers. However my experience with one that had a Edelbrock performer and a Quadrajet, small tube headers and a summit 1102 cam with a excellant tune up was okay, but still nothing to write home about. I've heard guys say these are excellant blocks to build off of but I've seen for myself that the quality of some of them was less than outstanding but that was way back in the late 80's and early 90's. I would think by now they've likely gotten the issues worked out and are somewhat better quality. I myself would never build one, even if it was given to me for free. I don't use flat tappet blocks, I only use roller blocks. But if I was in a situation where I had to build a flat tappet, I would find a cast in the USA block as I just don't trust the hencho en mexico blocks.

Your 350 engine

I didn't read all of the replys so maybe this was covered. The 010 last 3 digits are as he said..but..not necessarily a truck. I have about 6 of these in my shop. Depending on the pistons and cam and a lot more,,,it could be a LT-1 370 hp 350.probably not , but it does have the same block number. I have one here from a 70 vette and it is 370 hp plus and the pistons have serial numbers on the top of the pistons and a lot more.
It is probably a standard 350...but make someone look at the engine, you could have a diamond or a truck engine. I just sold a complete 010 engine from my 83 4 whl dr 3/4 ton truck for $350 just to make some room. If it was the LT-1 engine, it would be in the low thousands (original engine)
hope that helps you............get someone to look

Years ago, CHP did a great series on the target master engine. They started stock, and built it up in increments. I think there were 8 or9 different builds, each with dyne pulls. it's interesting reading. Perhaps on their web page?

Eds, perhaps I should have given more detail on how I know it's a target master engine. For starters the 3970010 is most likely the most common casting number as well as the most sought after blocks for high performance use.
The 3970014 which is it's twin brother was casted in almost the same number of years and the years themself.
In the old days the Target Master engines had the casting number 3970010. They also used the common 442 casting number cast iron crank that came in tons of 350's. The heads are the 1.94 intake 1.50 exhaust valve sizes with 76cc chambers and they carry the 993 casting number which was also common on smogger engines in the 70's. All of the Target master engines had the letter "M" on the deck surface and no suffix code. The "M" indicates GM of Mexico. The GM of mexico plant only made these engines at that time pretty much exclusively as no suffix code indicates it never came in a car or truck application. If GM had to replace a engine under warrenty it would have carried the "CE" code which stands for crate engine. By the time the target master line came out the 010 block was no longer in production in any of the american or canadian plants and neither were the 993 casting heads. When the target master was created as a low buck GM replacement crate engine the block, heads, crank, rods were all based off old school heavy casted parts. The idea was to use these parts to give the impression only heavy duty parts were used for maximum reliability which was used then as a selling tool. GM figured the customer would be pleased to know the stock replacement engine they were purchasing was made with heavy duty parts.
More info on this is look at the dates of the casting numbers used. Then check the dates on the target master engines.

3970010 302/350 69-79 145-370 car & Truck 2 & 4-Bolt Most common
3998993 307/350 68-79 1.71/1.50 1.94/1.50 76cc
Later on, GM dropped the 3970010 casting number and changed it to:
10036033 350 4-bolt Mexico cast Crate engine
and last but not least:
Code Engine Plant
F Flint (Motor)
S Saginaw Service
H Hydramatic
T Tonawanda
K St. Catherines, Ontario
(McKinnon Industries Canada)
V Flint (Engine)
M GM of Mexico
