Something came to my attention, so I spent the last 5 minutes doing some online research.
This swap may not be practical . It may not even fit at all. But there is another 3.4L V6 out there. It has an iron block, aluminum heads, and 4 cams.
It's a Toyota. Which means there's a TRD supercharger for it. And the 5-speeds from any '80s-'90s Supra, plenty strong.
The thing comes with 9.6:1 compression, 187 HP @ 4800 RPM, 225 TQ @ 3600 RPM, and the basic blower kit eases that up to 251 / 275.
There are 2 different 5-speeds worth knowing: The W58 has ratios of 3.285 / 1.894 / 1.275 / 1 / 0.783, and the R154 has ratios of 3.250 / 1.955 / 1.310 / 1 / 0.753
I expect this to be a stronger block than the weakling used by GM under their TwinDualCam 3.4L, and that makes it worth knowing about.
But the rods are cast, so that limits the RPM potential, unless there are upgrades out there.
This 3.4 appeared in the T100, the '95.5-'04 Tacoma, the Tundra, et cetera. But for boost, forget any pre-'97 computer. Unless you wanna try Megasquirt.
This has a slightly bigger bore than the GM, and a slightly shorter stroke.

Ok, so how is less HP and close to the same in torque stronger than the 3.4 DOHC?

From 1991 to 1993, 200-210 hp (150-160 kW) at 5200 rpm and 215 lb·ft (292 N·m) of torque at 4000 rpm.
From 1994 to 1997, making 210 hp (157 kW) at 5200 rpm and 215 lb·ft (292 N·m) of torque at 4000 rpm.

People that have turbo or supercharged their 3.4 DOHCs have eclipsed 300 HP with ease.

But again, I have no idea what you're trying to prove here, other than there are other 3.4L engines available.

The 3.4L DOHC (GM) swap has been attempted in the 3rd gen, but I have not heard of anyone completing it. I doubt that anyone will try that hard to get a Toyota 3.4 DOHC in where the GM version barely fits, and could use the existing tranny (with a little bellhousing modification).

Stronger as in not cracking the main webs. I've seen plenty of pics of destroyed GM TDC 3.4 blocks from turbocharging them. I've yet to find even one report of any 'yota 3.4 block failing in any way for any reason.

Not sure what the point is either, and there are definitely better 6s than that 3.4, if I was going to go to a different brand than gm for a 6 for my camaro, it would be a mitsu 6g72, Toyota 2JZ-GTE, nissan RB26DETT, or even a mazda 13b-rew(yes I know its a RE, but power level and size is comparable to a 6 cylinder). Anyone that knows anything about cars knows there's better sixers out there than the iron headed mongrels our cars came with, I'm not sure about the rotary, but I am almost certain these can all hit 700+hp, I know I've seen the mitsu and toyota ones break 1k. I would love to see what the new gm and ford ~300hp v6s could do with mods though. If I ever go to a different platform v6 than the 6/60 it would probably be the gm 3.6 llt, which is technically a 6/60, but not the same engine family obviously.

The 3800 from a 4th gen with a front wheel drive supercharger I think would be better. I just read about a 4th gen top end swap over at a turbo Buick site, and it would certainly be better in one of our 3rd gens than a 4th gen.

Anything can be done though, I get accused of useless swaps too hahahahha.

If you want to do an interesting DOHC v6 swap, consider the Isuzu 3.2. I took the measurements, and it will bolt to the 60 degree V6 transmissions.

Just a thought.

There's something worthwhile about a swap where you can say you have a Camaro with a 3.4L V6. Noone's gonna ask you to pop the hood until after you win the race and take their money.
Run down to the yard, pay your $200 for the 3.4, pay your $100 for the 5-speed, spend another $1000 swapping it into your 'maro, then spend another $1500 setting up some e-bay Chinese turbo boost.
Lots of guys spend way more than that to do the 350 swap.
But swap in a weird displacement, like a Nissan VG33, then try to get the race: " Whatcha got?" " It's just the base 'maro, V6 ya know" " What V6?" "3.3L" "Say what?!?! Lemme see it"
So, which swap will pay for itself?
