I bought an engine rebuild kit from Egge , and passed it over to my engine rebuilder with the engine.
All has gone well, until he has now looked at the Valve Lifters and tells me they are about .001 oversize as they wont fit in the head, and also they are a different height.
My original ones are 2" tall, and the new ones from Egge are about 1 27/32" tall, plus being about .001 oversize.
When you order the 315 CID Poly kit and select valve lifters there is no option to choose a particular size i.e oversize.

I have emailed Egge for their response, but I am in Australia and keen to know that what came with the motor was the correct lifter. The engine was not running when I acquired the car.

Have attached some photos if that helps anyone offer an opinion.

I see some valve Lifters on ebay etc, as well, but I don't want to buy another wrong set. They don't offer detailed dimensions on these items, so guess I will have to ask ?

Thanks, Steve

Hopefully he meant block, noy head.... You might have lifters for something other than a Mopar, hemi, poly, LA, big block all have same diamiter lifters. Hemis, and hemi based Polys should use # 812 lifters for the early 361/413 big block. Not exactly the same as OEM but they work. One company makes 812s, but those are for S. B. chevy. Melling 812s are right. The LA lifter will work, but is taller & probably would need adjustable push rods, might be what you have, except for the width problem.

I have torn down a number of LA engines, big blocks and poly, early hemi and have never seen a lifter that looks like the ones sent to you from Egge. As George stated, these must be for a different engine sent to you by mistake.

Has your rebuilder actually tried to fit the lifters in the block? The height of the lifter body isn't as important as is the dimension from the lifter face to the bottom of the pushrod socket. IOW, the disc at the top of the long lifter might sit further down in the body.

I think that the standard bore OE PN for the 315 Poly hydraulic lifter was 1555 176 (1555176 when searching). Should look something like this one:

Part Number:

2808569 [supercedes P/n 1531204, 1555176, 1731618 1851904 & 2084029]

The short lifter with the wide band looks to be a #2011, common for the LA engine. They require a 5/16 dia pushrod tip whereas the early engines use a ¼" tip.
Generally, they do not properly connect with the oil feed hole in the lifter bore although you could modify the hole with a Dremel. You will also then need adjustable
pushrods to compensate for the length/height......if you have cut the heads, deck or use a reground cam you will still need adjustable pushrods but with the proper lifter
you will use ¼" tip t&b.

I took some of those equivalent numbers and went tappet hunting on Rock Auto. That resulted in 3 options.

https://www.rockauto.com/en/partsearch/?pgname=Engine&partnum=280856...

The Melling option (expensive) listed sizes which might be useful as a comparison.

Two additional thoughts. AFAIK, TopLine Johnson aka Hy-lift, is the only US manufacturer of the #812 lifter. I asked the EngineTech folks and they admit that
theirs are made in Thailand or some such place. Melling would not tell me the source of their product.
You can buy direct from Topline.
Also note that there is another 'Johnson' brand and it is NOT the same as TopLine.

Melling; That doesn't sound good... Johnson: Someone is doing trademark infringment, also not good to muddy the waters..

Thanks everyone for all the info. I'm nearly there !!
I'm just seeking confirmation if anyone has used a #812 lifter with the standard 9 3/16" pushrod.

Now I understand the overall height of the lifter is the not the issue, rather the measurement of the push rod seat in the lifter from the base of the lifter.
hence my question.

Thanks, Steve

If anything has been changed from the oem design, like regrinding the cam, decking the heads or block, or using a fat head gasket then the amount of lifter preload
will change and can certainly affect runability. This is the reason for installing adjustable pushrods. I suggest using Smith Brothers.

One of these Mopar-related shops in Australia should be able to help you. Unfortunately, none appear to be right close to Sydney.
But they will have phones.

Good luck.

Does anyone have any experience of the valve lifters supplied by US Seal Co,. They seem a lot cheaper than Melling and others. Their relevant P/N seems to be LIF8.

Does anyone have any experience / opinion of the valve quality?

Thanks

Interesting.....their website is dated 2023 which, may or may not be a 'thing'.
The website also only indicates seals as their product line. I did not find lifters. Perhaps I didn't look deep enough.

Given the total cost of your rebuild, is an additional $200, m/l, that much of a problem?

Sorry for being vague.
Here is a link to the item

https://ussealparts.com/catalogsearch/result/?q=lif8

Not wanting to be too defensive, but I am retired and doing this restoration on a tight budget and a pension, so I do try not to pay any more than I need on items otherwise the whole project would be way over an extra $200. $US, and much more in my local currency $AUD)

That being said, I do appreciate the interest and time it takes to offer responses. All input accepted and appreciated.

thanks, Steve

Steve,
I completely understand the retired thing....most days I am just plain tired....living on pensions and investments never keeps up with inflation so we are always struggling to get work done.
I do feel bad for folks who have no skills.

The link shows a proper listing for 'some' of the possible applications however, the same list also includes several 68-71 engines which would be incorrect
as MaMopar changed lifter and pushrod design for the 68 model year.
....can't be both......

The only 'problem' with the Jensen listing is that I do not see any reference to year. Jensen started using the B&RB in 66 but continued for several years.

Well, the answer is I purchased a set of US Seal Co Lifters, P/N LIF8, and they checked out to be a perfect fit.
They were a good price on ebay, so I am happy to have that dilemma solved.

Thanks for everybody's contribution.
