Whats the best way in pulling 390 engine? Opinions please

[ximy]

I've got this one: http://www.northerntool.com/webapp/wcs/ ... _200305213

Great price, works as good as any I've ever used, and came with a free load leveler.

Got free shipping with their "Ship-To-Store" option.

That's a super buy!!!

I've got that exact one too. Just pulled my 302 out with it this evening. Had to remove the hood but it went high enough to clear the radiator support with no problem.

There are some great ideas about pulling engines here. Great thread. But I have always found that balancing the engine either taking it out or installing it has been a pain, until my friend showed me his engine lift tool. He took a piece of 3/8" plate and cut it 4" by 6." He then welded a 3 inch ring onto one side of the plate. He took the carb off the engine, measured where the carb stud bolt patterns were, drilled out the plate and then bolted the plate onto the carb studs. He hooked the chain hoist, which is in his well equipped shop, into the ring and out comes the engine and it is balanced. Hood off of course. I know it sounds incredible but it works. Oh yes, the tool has been drilled out several times for all kinds of engines and is at least 40 years old! The first time I saw it I damned near died but there is enough tensile strength in those four 5/16" inch studs to hang an engine on. The biggest engine I ever saw on it was a GM 427 truck engine he was installing into a C65 3 ton. And, he loans it to me anytime I need it. Works real great for removing and installing these heavy FE intakes.

Pictures, dude! :)
And like.
More than one angle too, ok? ;)

Anybody else got something similar post 'em up too. ;)
I've got half a hunk of structural eye-beam (tee) that'd work real good
for this but want some pictures before I go cuttin' and drillin on it. :)

Sounds like a great tool.. What about lifting it when an aftermarket intake installed? I'd be worried about the aluminum stud mounts giving out. I have dropped one of these and it is a very ugly sight to watch! Using less then grade 5 bolts will do that. Dumb @#$

A friend told me about using a similar tool. When I pulled my 360 I made one out of a block of hardwood and a U bolt from a muffler clamp. It worked great.

I'm not an engineer and I'm not suggesting you try this but I'm sure one 5/16 bolt has enough tensile strength to hang a 460 on. That is just a straigh pull on the bolt, the problem would be if you would put sideway force on the bolt. If the plate is made nice and strong you could hang a lot of weight (460 w/transmission) from that plate bolted down with 4 bolts. Just my thoughts and if someone wants to disprove what I've said than I stand to be corrected.

Bolt strength chart

Cool post, thanks for the chart! :)
But what does it mean tho? LOL :)

I'm with Jake on his post, top to bottom, correction-position and all. :)
Because of what I've seen small chains take. (grade-2-like bolt-material)

For me I'm more concerned about the threads. And wonder if that's
what that chart is more about, the strength of the nut's threads and
so rating the "bolt size" at such a low tensile strength as 6000 psi?

Also if you have 4 bolts holding something the chart might be taking
that into account too? The safety factor is such that you can multiply
those numbers by 4, no sweat? Because like dually tires you rate the
two together lower than each-one can take, for obvious reasons.

I need a copy of the "Machinery Handbook" huh? LOL :)
(stopped and put one in my cart at Amazon just now ;)

6,000psi steel is the baseline that the chart uses for the load listed to each size.I will find the baseline foe grade 5 and 8 it will take a bit though
that is when they will pull out,I think that is with 5 threads engagement necessary for full strength
yes it is a very handy book even an older copy

[70_F100]

I think that is with 5 threads engagement necessary for full strength

Not to dispute what you've said, I've always been told that full strength is achieved when the engaged thread length is equal to the diameter of the bolt.

If you take a standard nut, it's generally the same thickness as the diameter of the bolt it screws on to.

That would disprove the "5 threads" theory, as 5 threads on a USS bolt would give a different engagement length than 5 threads on an SAE bolt.

[eggman918]

I think 5 thread is for other than steel, like cast iron and nonferrous metals
But I can not argue with you as I can not recall the source.

[Alvin in AZ]

Either way a good 1" of 5/16-18 threads into a 351W's lower intake, x2 would hold it, suppose? :)
Taking "bets". ;)

No flywheel or pressure plate or A/C compressor or alternator on it, just the exhaust manifolds.

Just theorizing at this point. But at some point soon I'm going to try it. Seems to me, all it can
hurt is the sheet metal oil pan and/or valve covers because the F250 parts truck is already a mess
being an ex-company truck and all. ;) Lift it up, push the stripped-pickup back out of the way.

Then set it down, re-position the hoist, lift it again and back the '75 f150 under it, sit it down in
the bed on tires then strap it down. Anyway, that's the plan. :)

ps- The 230 pound E4OD is easy as pie to move around with a hand truck. :)

[eggman918]

I think that you are safe as long as they are tight and properly supported
the difference in strength between coarse and fine thread bolts of the same grade are due to difference in thread engagement with the fine threads being stronger
