For several days I have been uselessly searching for dimensions and drawings from the internet. I'm trying find information about the Vortec 4200 inline six engine that I'm planning to use in my next project.
I don't yet have the engine in my hands so I cannot measure the dimensions myself. My shipping method for large parts is slow and the shipping time will be measured in months.
I have even seen a CAD model of the engine but it seems that the makers aren't very willing to share it. Currently I'm looking for the exhaust flange pattern, flywheel flange and bellhousing bolt pattern. I have a rough estimate what the flywheel flange might be but even the source thought that they might be inaccurate. I haven't even been able to find what's the outer diameter of the starter ring gear.
Why isn't the internet sharing flange and bolt pattern information? This isn't the first time that I have had problem finding these. Most of these are really difficult to find. It's not really a business secret if anyone who has these pieces can measure them too. Stupid internet, be more useful.
New business model for someone who likes to sell something:
-acquire laser/water cutting machine (or hire some company to do it)
-draw some flanges yourself
-cut and sell flanges
-share flange drawings and ask people add more
-offer discount to people who have shared flange drawings (verify with a photo?)
Or skip the selling part and just make a webpage with flange drawings and links to good cutting companies.

The only 4200 Vortec I know of, is in trailblazers, envoys and the like.
I do believe it's the v8 in them.
A 4.3l Vortec would be a better start, at least. If you don't mind a V6. I Mean it's a 350 v8 with 2 cylinders chopped off.

Anything older and sort of common, even if unusual, I've not had problems finding in the past after enough work (given: quite a bit). In my case, mostly the Rover V8. More modern things, people just seem uninterested. It does appear that the Vortec 4200 is easiest installed to something that a 4l60e auto can be adapted to because the bellhousing pattern is unique to the Atlas and they weren't sold with a stick. I did find a guy who has a flywheel available for it, but that still leaves some difficulty with the bellhousing - possibly best locating a donor on an auto and cutting it up, although you may have had making just an adapter plate in mind.

The 4200 (or Atlas) is an inline-6. It was only available in the GMT360 family (TBs, Envoys, Bravadas, etc.).

Actually, an update: that page I found has a forum , and it seems one of the forum members has made adapter plates.:

Reading a little further (not to keep spamming your question), it seems that the Colorado, as it uses a different version of the Atlas and a manual, has a bellhousing which fits some Aisin and other manuals (and of course has a slave cylinder possible, etc.) but Colorado clutch parts don't fit without being adapted, getting a new flywheel for the 4200.

I tried to join the forum in last year. For some reason the administrator didn't like me joining from Finland and even banned my IP. I contacted him but still my username remained inactive.
That adapter would allow SBC compatible transmission but I was also trying to find some other options. Large ZF transmissions would be easy to find in Europe (from large engined BMWs) but now I cannot verify how hard it might to build an adapter.
The smaller siblings of 4200 (3700 and 2900) came with manuals but the flywheel isn't compatible. The transmissions would be but they aren't rated for huge amount of torque.

I really want to have an inline six. The Trailblazer and its siblings had the 4200 I-6 as entry level engine but most had a V8 option too.

Yes. The easiest method would be to use Colorado manual, original flexplate and a button type flywheel with a multi-disc clutch. The button flywheels can be bought as an undrilled blanks and it would be quite easy to machine them with a proper bolt circle.

I suspected you'd at least fallen across the website, but didn't know if you'd gone forum-delving. How very odd that the admin didn't want you in - he must have been one of these types who flags all unusual circumstance as an indication of a problem poster or spammer and can't be shifted from that position. There are some circumstances where that's true (here, one might consider SuperKiwiZorro/IHateAmericanCars or to some extent the Italian poster Roberto G), but it's an extremely narrow-minded way to moderate. Then again, I tried to join an approvals-only forum for Forza racing a while back and never got approved there either.
What a nuisance - it seems almost as if you'll need to find a junker and proceed with a lot of your plan without verification... although some of the members of that forum, including the adapter plate maker, seemed to have their emails posted. Direct contact might work.

I guess my IP address looked somehow suspicious and he was too busy to permit to to enter even after I asked him about it. Their forum doesn't look too busy to drive away all non-native English speakers though.
I've been trying trying to contact some 4200 hobbyists directly. The guy who managed to shove one 4200 into a MkIII Supra gave one one important hint.
