Hey guys sorry to bug about this topic but I hadn’t found a clear answer to this one yet.

I own a 1985 G-Body that I believe has the factory GM 4.3 V6 fuel injected engine and what I am assuming is the factory transmission (column shift automatic) as well and was contemplating a rebuild.
However my uncle owns an older model Chevy pick-up (I don’t know what year) that he thinks has a 327 (but it’s definitely a V8) and a TH350 that he offered me at a bargain price since he’s gonna scrap the rust ridden frame but pull the motor and transmission out and won’t be doing anything with it...

what do you guys think it will take to install his engine and transmission in my El Camino?

Is it even possible to do this correctly going from a fuel injected 4.3 engine?

I have absolutely zero experience with this kind of job, but luckily I’ve got family that’s done this before so I’ll be working with them to make sure but I thought I’d run it by this forum first to make sure I’m not getting myself into more than I can handle.

Do you live in a state that has strict emissions control laws? If yes, you need to consult the laws to know if this is an approved swap.

4.3 is basically a sawed off 350. 327's are great engines, probably my favorite. It's gonna fit with very little trouble, trans mount and driveshaft might be shorter/longer, but I doubt it. Like the other said, check your local emissions regs. That's the rub, I doubt if you can legally do it. 327 has to be pre '68 (GM switched to the 350 in '69), so cam and heads would be dicey. If you can talk to the state, they may let off with cats and O2 sensors, an EGR intake, and a feedback carb.

I looked for a C-10 for a year, they're all rotten, even the CA trucks. Gave up and bought my '68 El Camino.

We don’t really have emissions here in Washington State I’m sure it’ll pass just fine 🤫

Then you're golden. One other thing, the early 327 engines didn't have bolt holes in the heads for accessory drives like A/C and alternators. If you need all that to work in the same configuration, you will need those mounting points. All the later 350's had 'em, so a head swap would be easy with the engine on the ground. 2 barrel or 4? I have an extra 1968 4 barrel stock intake if you need it, free, just pay shipping.

If you really want to get wild, I have a 1962 327 Corvette clone I'll sell, brand new, 10.5 to 1, closed chamber double hump fuelie heads, KB pistons, eagle rods, .030 over, standard crank in a 2 bolt block, moderate Lunati hydraulic cam (282 dur/495 lift). It'll need premium to run on the street. Could be fun!
