In your guys expertise(i think that the word). how long would it take an confidant do it your selfer who has never pulled or installed an engine, to do an engine swap. i have all the air tools and a cherry picker(oviously).


Thanks
 
i think my first attempt it took me like 1hour and 30 minutes to pull it and maybe like 2 hours to reinstall?? can't really remember cause it's been like 10 years ago and bout 5 motors.

i can do it now in like a couple hours to remove and install
 
really it it only takes that little time?

what would be my best bet in a 350 find a barn fresh motor and go through it. or spend more money and a running parts truck.

I am just kinda planning just incase i end up peicing together a truck.
 
i'd go for a parts truck. your odds of finding a barn truck that runs and the carburetor all not being gummed up or rats nests all over are slim. i'd find a decent parts truck and run with it.

with a automatic tranny i can it in that little time. manuals always seem to be harder to line up cause of the pilot shaft and such
 
Hate to say it, but GM has some GREAT crate motors ... fifteen hundred bucks for a long block doesn't seem so cheap, but it's all new, not reman, and as long as you don't go crazy with replacing other stuff while you're in there (BTDT, oy! :deal: ) it can work very well.

ya i got one of those $1800 dollar deals in my blazer. i didnt do the engine swap i paid for it. my uncle did it when i bought the truck. with everything it came to $2100, wich include new intake and all that other good stuff.
 
I think my last engine swap took about six months. Oh wait, I'm still not done, but hey is has only been 6 years.
 
honestly, if you have never done it before, I would say it would take at LEAST a weekend. It isn't very difficult, but when you get all the accesories off, and back on, it does get involved. and you will always find something else to replace when you're in there.
 
Take LOTS of before pics of how ALL the accessory brackets bolt on. Nothing more frustrating than trying to remember where they all go back.:doah:
 
It took me a weekend to do mine, I laid all the parts out neatly and bagged anything small. The only pain in the a$$ was lining the motor up with the trans, and those hard to reach bolts. I swaped in a rebuilt motor from my friends truck. (he was junking the truck) all in all it was not to bad. It was my first time :D
 
i just pulled a motor last week. it took 11/2 hours disconnecting everything
and pulling the motor out. then it took about 3 hours transferring everything to the new long block. last night i lowered the motor down, lined everything up and dropped it into place in about 45 minutes. now i figure another 11/2 to bolt everything up and plug everything in. well see:rolleyes:


Just remember, take your time, mark all your wires, add oil and antifreeze,
and be done.
 
the most time consuming part is proper prep. peanut butter jars are life-savers. label them, plop the parts in, add a little cleaner, and your parts are organized and clean.

the actual in and out of the motor is very quick if you have any clue what you're doing. the highest bellhouseing bolts are the tricky part. took about 30 minutes to unbolt tranny, etc. and remove engine, then about 45 minutes to get the new one in there and bolted up. took another few hours before i had everything bolted up, double checked and ready to run. that was spread out over a year, though. took me a long time to get around to it with my job and weather, but the actual work was fast.

x2!

And looking for new hose clamps and new kickdown linkages and the column shifter and exhaust didn't line up and... and... and...

I guess that is what I get for putting a 351W where a 289 should go (taller deck hieght). And for putting it all together with parts from three engines out of three different vehicles. And rebiulding the engine halfway through, and a cam/manifold/carb swap, and deciding that was a good time to redo the front suspension and... and... and...

It is good to have a project that is not your DD.

how could i forget about that? it took me nearly an hour just to bolt my oil pan on. i didn't realize how badly it bent. should have just bought a new one. and the y-pipe was a pain to bolt back up because i tweaked it offroad at least once.
 
speaking of stuff to redo, why not do the ORD engine cross member while you've got room?
