What is your fastest time to drive a car in, pull the engine, swap in another and drive it out?

It has been awhile since I have done this.
Years back when I was short on cash, I'd swap in junkyard engines with no rebuilding done to them and have the car running in a day.
Back then, my cars were fun but not show quality. I didn't take the time to repaint engine bays, change anything or make upgrades except to swap engines. I've done several.
I had a 350 in a station wagon and a 305 in my Camaro. Both ran but the 305 was tired. I did a car for car swap and sold the wagon.
My brother had a Camaro with a dying 350, a buddy of his had a great 350 but his Camaro was a wreck. Nose to nose on the street, we swapped engines from car to car and the wrecked Camaro got junked.
I used to be able to do this in one day. This was with limited tools in less than ideal conditions.
Now I have plenty of tools and a roomy shop. I plan to do a 360 for 360 swap in a couple of weeks to this car:

The car will eventually get painted but not right away. If I did have a plan to "do it right", I'd strip down the engine bay, weld up any and all unused holes and paint it the color that the car will be. For now, I just don't know what color that I want to paint it so I won't do anything but clean things up a bit.
This time I plan to drive it into the shop....

.....Pull the running 360, install the rebuilt 360 and then drive it out.
The exhaust will stay in place. The transmission will stay in place. The 360 going in is a 9.5 to 1 roller 360 with #308 heads, 1.6 Hughes rocker arms, a mild roller cam, Air Gap intake....

Those headers came from FABO member @MidnightSwinger. They were test fitted to see about oil filter access. They will go in later, not the day of the engine swap.
The engine coming out is a late 70s 360 from a junkyard. In 2000 or 2001, I helped a buddy of mine and his kid pull this engine, strip it down and after he had it cleaned and honed, we screwed it together with stock pistons. He built a better engine later and I bought this from him.

It has about 8 to 1 compression, #308 heads, a MP 280/474 cam with a Weiand dual plane intake. The car runs pretty strong for being such a low compression mill.
I'm keeping the 8 to 1 360 for another car.
So what are your stories? Who has tales of their one day engine swaps? Maybe less than 6 hour swaps?
 
If four gearboxes on a conveyor frame counts - 3.5 hours on a very hot day before Christmas. :lol:

In 1975 my friend and I were 20 years old. We drove his 69 Fury under a tree on his parents lawn at noon and pulled the 383. Stuck in a 440 that was fully assembled, drove off at 5:00. Still have the chain hoist.
 
Best we did was starting at 3 pm on a Friday afternoon and turning the key at 630 the next morning, spinning up dust in the yard shortly after! That doesn’t sound all that great for a swap but it was a complete pull, rebuild and install in this old Ford F250, 460. It didn’t to go to a machine shop which helped, probably should have!

We also drank a lot of beer that night, which didn’t help out much either, but was a good time.
Oh and I was a lot younger then too! :lol: :lol:
 
My buddies 64 Impala blew a hole in a core/ freeze plug right behind the motor mount. We pulled the engine, replaced all the core plugs and painted the engine. We had it back in the car in a bit less than a day and a half.

Greg: You have a lift. It seems you will pull the engine from the top? If so, I am a bit surprised you are not doing the engine swap from below. Since I did this with my Road Runner in 2014, I vowed never to swap a Mopar engine out the top if I can help it. Going from below is so much more controlled and accessories/ headers can be attached to the engine too.
 
I’ve helped my dad swap out engines in about a half day, pulling both engines and all chevy stuff but that included the transmission also but back then we gave Zero F**ks about beating anything up and dad had a backhoe also. Thats a basic switch a roo lol. No swapping out anything from engine to engine. Just bolt it up and top everything off and go. My OCD now a days takes me 4-ever to do one.
 
I just grin at this thread at how we did things back in the day. I do recall swapping manual gear boxes , transfer cases on my chest because we didn’t have a jack that could do the job...My how things changed. I recall swapping 3.5 engine and trans then driving it out in less then one day into a newer Magnum with timing belt replacement.
 
5 hours. A friend blew the motor in a 67 Firebird. Pulled the dead one and put in a replacement in the parking lot of the Watergate Hotel in 80. after we convinced the local cops that we had not stolen the scaffolding we used as an engine crane, several of them stopped by to get a laugh out of this adventure. What you do to survive as a poor college student.

6hours on my BMW E46 m42 Engine out new Engine in.
I stripped a Fiat Punto Evo of all its Parts in under 3 hours.
 
Not engines but at the track we've done some quick repairs. Put a head gasket on a friends 340 in between rounds. I've gutted and repaired 727's between rounds. This year broke a waterpump. It was apart. They came by and put us on the clock with 5 minutes to be at the line. No radiator, fan or pump when the clock started. 4 1/2 minutes later I was suited up and belted in at the line.

One year at Indy for the Mopar Hemi Challenge, Charlie Wescott Jr blew an engine in his 68 SS/AH. Jr said "we're done, load it up, we can't make it to the line in 45 minutes". Then Sr said "yes we can". And they made it to the line in 45 minutes.
 
In the late 70's I was a mechanic at a Chevy dealership. Guy was pulled in with a 69 Chevy flatbed truck with a load of watermelons, and a blown engine. We kept GM crate engines in stock back then. Service manager at 3:00pm said extra $100.00 if you stay and put the engine in. At 7:00pm it rolled out the door. I could beat flat rate on most jobs back then, probably why I have arthritis and other problems now, just worked too hard when young.
 
I have swapped out a 1979 Mazda Rx7 Rotary engine in 4 hours. And drove it then blew out the clutch disk. I should have read the instructions to be easy on the clutch for thefirst few hundred miles. But Nooo I was like if it will catch a second now it will catch one later. Nope it shattered.
 
Never timed any of them, but I have driven dozens of buddy's or customers vehicles into my garage in the morning and done either an engine, transmission or rear axle gear change swaps or even all 3 in the same day and had them drive home that same night.

Going from below is so much more controlled and accessories/ headers can be attached to the engine too.

I want to compare these engines against each other in an apples to apples comparison, a low-tech dyno test of sorts.
The plan is to do a short drag race against my Jigsaw Charger with the existing 360, then with the roller 360, then later I want to swap in the headers and better exhaust pipes.
Using the lift is better for preserving the paint and detailing things well. To do that, the drive shaft comes out, the transmission and all the linkage and cooling lines, the K frame and LCAs, steering box and column then I'd need to bleed the brakes when it goes back together unless I pulled the calipers and hung them with the UCAs. Pulling the engine from out of the top means I can leave all that stuff in place.
