Those engine lifting plates that bolt to the intake manifold in place of the carb to lift the engine out, just seems weak but I have seen it a lot on 340 and 440's but never on a Hemi thou, strange. My engine pulls always get big bolts to the intake/head.

That flange was designed to support a carb...

I've used one in the past to pull a HEMI. but regardless of the engine, only a fool would pull a motor relying on just that plate, I always "safety chain/strap" an engine with a back up plan should the plate/hook/etc fail

I always use a chain to the heads.

Proof load for a single grade 2 5/16"-18 bolt loaded in tension is 2900 pounds!

That little steel plate that is bolted to the intake is 1/4" plate? Easily handle that load, probably designed to handle a higher load than the hoist without visible deflection.

Shear/load tension of the bolt means little if the manifolds threads are marginal, or insufficient thread length/engagement is an issue, esp with an aluminum intake!....always use a back up chain or strap that's attached to the lift/picker independent of the lifting hook or chain doing the work/load

I always use the plates now. I lost one engine that the chain actually broke and dropped it back in the engine bay. One exhaust stud went through an inner fender well and broke off, the other inner fender was damaged pretty severly.

Aluminum is a pretty soft metal . I would NEVER put that much weight on those aluminum threads .

I bought a kd tool one and the upright flat bar that you hook you crane to broke at the welds. I did get another one but afraid to use it now.

I made my own lifting plate when I was 18 years old and have used it for 30 years now on countless motors without a failure.
Used a cutting torch and AC "buzz box' stick welder long before I even knew what a mig welder was. I heated up that cold rolled and wrapped it around a 2" pipe and welded it into a ring, it has never even distorted.

I lifted gasoline truck engines numerous times which are much heavier that any big block motor. I trust it now.

No I would not trust some of those cheaper ones sold. I would re-weld it myself before using one.

I have seen some real unsafe rigging on here with with chains, so pick your poison.

I made my own as well since one was not available for the dual quad intake. With 8 bolts it was very secure and it even picked up my Hemi with 727 trans and also with the K-frame attached as it was going on the dolly prior to dropping the body over it. Worked great!

I see a bigger potential problem with lifting a Hemi by the carb to intake bolts. The bolts that hold the intake to the heads are small diameter and have a low torque spec. I wouldn't want to risk pulling them out of the heads or worse, breaking away chunks of the heads which has been known to occur just from over torqueing them.

i never liked the idea, even though it is an easier way to lift the engine. i asked tim at FHO about it, he said "some shops use them, we don't"

I agree with this. I wouldn't do it & never have not with the weight of a Hemi anyway & the smaller 1/4" dia intake bolts. Although, I do have a 4150 & 4500 dominator plates we have used all the time on my buddies engine when pulling them. I don't mind if the Brand X'ers fall on the floor....

In all the years I have never seen anyone post a picture of where the intake manifold either failed or cracked and the engine fell off. Have never seen it, has anyone had the intake manifold fail from a lifting plate?

I have never lifted a hemi with a plate, I always used a chain because none of my hemis had 4 barrel intake manifolds.

I have one that was made for my 440/3x2 Edelbrock and drilled a couple of extra holes to fit my 340/cast iron intake for AVS. I am a little cautious picking up a fully assembled 440-6 but I haven't had any problem. Used it about 10-12 times on two motor jobs for loading, unloading, painting and installing. The 340 seems effortless in comparison. It's difficult to find good balance points for hooking up a chain on a 426 Hemi. I would use a lifting plate if I had one instead of a plain link chain but my chain has some bent plates on the ends that work good for picking up a Hemi. I can say that a fully assemble Hemi bent my extra heavy duty home made engine stand back in the day. You definitely need the right tools for a safe job.

Uh-huh...

I did engine jobs everyday in the past...

This did the trick...

(Bolted to IRON cylinder heads...)

That's just like mine. I think I got it from Summit Racing. Works fine on a Hemi.

I made one just like that 30 years ago at the same time I built my engine lifter plate at my old job. My old boss was handy like that and that's who influenced me back in the day.

Then I loaned it to someone one day, and it never came back to me. I think I know who I loaned it too, but not sure and now the guy does not work for me any more. I rarely loan tools because of this BS.

But yes that is the best design lifting chain because the links can't slide through the lifting hook. And bolting it on with flat plates with the bolts tight in the heads is best. Tighten those bolts don't leave them loose.

I always use a lift plate ,,, never a issue,,,,
