Has anyone ever, or know anyone that has, put a Pontiac engine into an early model GMC/Chevy truck? If so, any recommendations for the transplant, i.e. headers, engine mounts?

no, but a guy brought me a Ford 1/2 ton a couple years for a transmission OH
I looked it up and all the books said 'C-6', when it got here it had a 400 Pontiac and Turbo 400 in it
Hum a "Frank-in-ford".... Sound like he was a closet GM person to me... :-) mark
Anything can be done. Some late 50's GMC trucks actually came from the factory with Pontiac engines.
October's Car Craft had a 1955 Ford truck with a late modle 5.7 Hemi in it, so anything is possible.
My cousin's swap list from the 60's:
Red Ram Hemi - 50 Ford pickup
318 V8 - 1956 Mercury 392 Hemi - 57 Chevy convertible 354 Hemi - 1951 Crosley Caddy V8 - 1961 Impala SS (BUTCHER!) Buick V8 (nailhead) - Metropolitan 409 Chevy - 57 Buick CenturyIt only takes a big hammer to make anything fit into anything.
BOP/Caddy/Pontiac engines can go into a chevy truck. You need to modify the front cross member, and move the motor mounts. 500cid.com I believe makes headers for them. Or you can get an adapter flange for chevy big block headers. They make adapters to go from BOP engines to chevy trannies, and from chevy trannies to BOP trannies. They also make the "ultra bell" which replaces the stock transmission bell, and can bolt up to either a chevy or a BOP.

With an electric welder, a torch, and a set of tools, you can do nearly anything. I had a friend that put a 428 Super Duty into a 63 Chevy one ton Tow Truck. It could almost beat my 66 GTO in the 1/4 mile.
It was a whole lot of fun helping my Dad grease a 350 into an old Willey's jeep....
I had a Triumph TR-7 with a chevy 350 and chevy auto tranny in it. If that can be done, anything can be.
I still remember the look on the poor Porche 911 T owners face when I blew him away.
Damn, would have liked to seen that. I do know a guy that put a 350 in a VW. He also took a Bronco Frame, mounted a Jeep body to it and took his blue printed V8 off of his mustang he race in NH and put that in it. 402? He called it a BEEP.
Every see a 4x4 do wheelies?
It was fun, to be sure. only mod that could be seen from the outside was a small hood scoop to accomodate the carb/air filter. O, it had the chevy rear-end in it too - a 4:11 I believe. Didn't go that fast, but it sure got there in a hury.
back in HS I had a '78 Ford F100 that i swapped in a '72 Olds 350.. it was fun until I blew up a couple 3 speeds and a 4 speed... gave up on it when I broke the pinion in the 9"

That's what happens when you put a real motor in a Ford.

it's what happens when you start out with a 200,000 mile 6 cyl truck and drop a muscle car engine into it... things will break.

I have one of those motors (1972 Rocket 350 that is)....jest awaiting the donor car to go into...........
transplant, i.e.
Snippety, snippety, snip.
A while back, when I was still in highschool, I put a 6.2L diesel and TH400 into a '75 F250. Put some true dual straight-pipes on it. Some of the confused looks I got at stoplights and in parking lots were priceless... ;-) Had the original 4.10 gears still in it... that truck was a pullin' machine. Got 18-19 MPG too!

Its old but I cant resist. Triumph actually had a model called TR-8, its was the same as a 7, but you guessed it, it had a V-8 under the hood. A step further, there was an MGB-GT that came with a V-8, 2 production years only. Tight fits I have built, besides a dozen or so V-8 Vegas, 71 pinto wagon with a 351 Cleveland, the hardest one, probably the 74 Plymouth arrow we shoe-horned a 340 into while stationed in Germany. Most fun, after the Vegas of course, the 85 S-10 pick-up put a 472 caddy in, and my favorite, after the Vegas of course, the 1973 Chevette Scooter we put a super-charged Buick 3.8 and a 700R-4. Narrowed a 10 bolt out of an S-10 with 3:83 gears. A chevette that would pull the front wheels off the line, run an 1/8 mile in

General motors put Pontiac engines into early model GMC trucks when they were manufactured. From the time they came out until about 1957 or so. Originally, that's what a GMC was. It was a Commercial grade Chevy truck with a Pontiac engine (because Chevy didn't use pressure lubrication, and Pontiac did).
Kudos to John for not asking the stupid question ("is it possible to put a Pontiac engine into a pickup truck") that was actually answered. He's too smart for that. He knows a dozen people wnet to the moon. His actual question is if anybody knows anybody that did it.
Unfortunately, he didn't say what he meant by "early model". To me, an early model Chevy truck would be a 1930 model. Luckily, the engine swap is almost the same up until the 1950's. Sadly, he might actually have a 1984.
There are two problems with the early model:
There isn't a lot of variety with Pontiac oil pans, but as tall as the old trucks are, I think you'll be able to get enough clearance. Slide the engine back far enough to get the oil pan behind the front axle, as far as you can.
