Engine hoist brackets

Rover V8 46D prefix engine:

I have bought some nice stainless steel (I know, bling!) brackets. I have three of them. I can work out where the two smaller ones go but the one that is much longer I cannot. It aligns up with bolt holes on the header but the upper bolt in the bracket is smaller than the rest and is too small. Before I take out my drill and enlarge the hole can someone confirm I have this right.

1. Small bracket with straight angle cut edges at top goes on the rear of the RH head (drivers side) on the valley side.

2. Small bracket with rounded top goes on front of the LH head on the valley side.

3. Large bracket goes on rear of LH head on the spark plug side.

Cheers,

Adam.

There were many variations of heads with 2,3 or 4 fixing holes in them. Check the Rimmer Brothers website, they have all the info.

Chris, I know what heads I have and the brackets but there many combinations of these fitting. I decscribed what I believe is the correct orientation etc but the long bracket hole for the bolt is too small and if I were to drill it out then it would fit where I think it needs to go but before I do this I wanted to check with someone that the long bracket is mounted on the outside of the rear passenger head. This being the case I can drill it. I am a little mystified why one of the bolt holes in a bracket is smaller because all the bolts holes on the front and rear of the heads on mine are the same!

The brackets you've bought are intended for early heads which have varying bolt sizes and bolt hole positioning.

I've just found this out when fitting the serp front end to my engine which has early heads. Theres a bolt hole in the power steering pump which goes to fresh air on the head!

I think you're going to have to pretty much make them fit in the easiest way possible which still offers enough support for your engine when lifted by them.

I shall make it fit then. As for giving enough support, all brackets will have two bolts each to the heads and the passenger head will have brackets to the rear and front. The driver head will have one bracket at the rear. So three brackets with 6 bolts in total should be enough to lift engine and gearbox not exceed 230Kgs. Not sure of bolt size but they look like 3/8 X 1" long

Yup that will be enough. I've seen the yanks picking up engines and boxes using square plates bolted in place of their holley carbs using the 4 small carb bolt holes so your 6 bolts and 3 lifting eyes will be more than enough!

Yes I have seen those on programmes on Sky such as American Hotroad and Chop Cut Rebuild and always hold my breath! The engines and box are probably a lot heavier than 230Kg also!

I have made two plates to hoist a Ford V8 into my Scimitar GTE.

The engine alone weighs 210kg, then I have the Lakewood steel bellhousing which is a very heavy beast. The gearbox will be mounted next week , I will have the adapter plate lasercutted tomorrow I hope! The gearbox is a Toyota Supra R154 which is also a very heavy part.

Of course the other thing is the bolts are not installed so the force is shear which goes against the principles.

250kg/4=62,5kg per bolt. I think the bolts are about 8mm thick, the threading is about 25mm deep. According to my principles (common sense) it's good enough for the load applied.

I think you are safe, well the Americans get away with less but my point I am making is that the load is not across the 8mm bolt shaft but the thread itself which is far smaller but as you say the depth is 25mm. After all the fasteners are for a temporary use, i.e. when lifting the engine. In the case of suspension you will find good design leads to fasteners installed in shear or ideally double shear.

P.S. 250kg is that the total weight, i.e. engine & transmission. I believe the RV8 is 230Kgs all in all and 250Kgs seems light for an american engine.

No, the weight for the gearbox is not included, haven't mounted it yet. 250kg is just the engine + the lakewood bellhousing. I wouldn't be surprised if the gearbox weighs 50kg. It's pretty heavy. But it may be worth carrying the extra kilos, people says that this gearbox should be almost impossible to break. I've heard estimated max ratings like 1000nm/700hp.

So the total should then be 300Kg with Iron heads..

I will fit aluminium heads later to reduce the weight.

Here is a page with some weights and dimensions, the Ford 302 isn't light as a Buick/Olds 215 (=Rover!). But it's not heavy as a Chevy either.
