You boys are doing a fine job.
I am haveing problems posting pictures from my phone after the forum change. I'll keep trying to get them to load and get it figured out.
But the roller lifter setup is actually verry simple. I ordered a piloted reamer to pilot in the original lifter bores and ream them to the new diameter. In the block between the lifter bores is a square hole, I find center between the lifter bores for a cylinder and I bore that square hole to a round hole, I can't clean up the whole thing or it gets to thin, but there's room to get a 7/8-14 thread in that hole. I made a plug with a flange on it and drilled and tapped the center of the plug, threaded the outside 7/8-14.
I made the dogbones to hold the lifters from some old take outs I cut and welded to a new plate with a hole in the center of the plate.
Now a simple stripper bolt with a spring on it comes down from the top of the block and goes through the dogbone and threads into the bushing I threaded in from the bottom. All this holds the dogbone in place, the dogbone holds the lifters from rotating and puts some downpressure on the cam.
The only trick is finding lifters of the right length to engage in the block material, a small enough diameter to leave plenty of materal in the block for strength and dogbones to fit in the block.
The billet cam isn't that big of a task. It takes a while to turn out a blank, and a cam grinder can do the rest.
It's all about getting the proper valve opening rates for the parts used.

You know, I have the same philosophy when I see someone doing something that I don't understand. He/she must know something that I don't.

Well put. Wi50 has posted some info in the past that a special someone was unable to digest causeing weeks of argument and a $200 offer to see the part. Lookinf foreward to see more pictures and keep up the great work. Edited by Rod B - 19 Jan 2012 at 7:44pm |

Nothing like experience . Just asking questions . Had to process through them to. Changing something as small as lifter diameter . When not thinking about it can leave one scratching his head some times.Does with me any ways. Kamp dont let the reply on the cylinder head make you mad .

I was navigating a rather large vessel through a rather small channel once, and noticed a towboat operator doing something that I thought was very, very strange. I asked my dad what the other pilot was doing. My dad's reply was a piece of wisdom I'll never forget:
"I don't know, but he is obviously aware of some aspect of his situation, that you're not". Which translated to everyday life, means that when one ventures to open his mouth very wide about how another individual chooses to address their own challenges, he runs a substantial risk of finding his own shoe in it. After seeing WI50's work, I'm thinkin' he knows a whole heckuvalot more about what he's doing, than anyone else does... and I applaud his work- very, very nice. The engineering, forethought, and workmanship of anybody's project, is a testament to dedication and vision- the stuff that turns the ether of dreams, into reality. I appreciate seeing things like this posted, but guarantee that if I could be there for the "It's Alive!" moment occurs, I certainly would! There's no treat like feeling sound and fury! |

lifter cant spin in the lifter bore if it does so much for the roller. mushroom lifter is about 1.5 inches in diameter when you go to the roller you will be smaller say a .800 wheel . have you figured how much more duration it will require to open the valve at the same speed as the mushroom lifter ? |

The lifters are not keyed, but held in place by another method. The whole trick is finding a lifter of correct useable length and haveing the base circle of the cam keep it in the correct operating zone. It's quite simple once you see it. I should get time to finish it shortly and then I'll show a few pictures.

I got the liners installed in the block, the billet cam blank made, and have been working on a rev kit to hold roller lifters in place but have been too busy with other projects to do much on this allis engine for a while.
I'll snap a few pictures on my phone sometime and post up of those items.

Prince Vallium to the rescue please! It looks like great work to me, you boys need to settle down a little, remember, we all love Allis or we wouldnt be on this site. Lets take it easy on each other, just an idea, please dont jump down my throat, Trev.

Why not. Young Blood has won 5 NTPA championships in a row with a 426 in a class that probably allows over 600. But what do I know...I need to get a life:)

To clear up someones confusion there is a flange on top of the liners for them to hang on or seat in the block. They press fit into the bottom counterbore only to seal. They need to hang into the crankcase to support the piston at BDC.
Now I offset bore the blocks to gain clearance for large bore diamters. The flange hangs slightly into the original head bolt holes but it gets clearanced a bit. I do not want to leave a straight wall liner and seat in the bottom counterbore for strength purposes. I want that flange on top of the sleve to hold the liner in place, and by pinning the bottom of the liner I now help tie the block deck down. Now I do not need much of a flange. I have a slight undercut radius (to allow clearance for the radius) under the flange to the barrel, an undercut radius is stronger than a square cut. There's still .100 of material for the flange to seat on all the way around. .100 is plenty and would likely be fine on less than half that.
I leave the flange .300 tall and I cut the counterbore in the block .200 so the liner stands up .100, giveing me something to press against when we assemble a block.
By the way Mack, that pressure plate is just a junk one for measureing purposes, I was out to Atlas Tractor last week to pick up our clutch but it wasn't quite done. Waiting on the pressure plate and floaters. But at least I have enough now that can set my tower height and figure out my finger to crankshaft flange distance, figure my crank flange to throw out berring dimension and the depth of the clutch can. Now I can machine an adapter plate of the right dimensions to get the clutch can on the superstock engine and the complete package in the component chassis.
Yes Aaron, the last POS stayed togather for a long time, still going strong, some idiot has been worried about it since I posted some pictures of it a year agoe, though it was built 10 years agoe. Sure was nice when I didn't know how to post pictures.

AAron get a life .if it has a square step its good if it has a radius step . he should turn it square. but he could be planning on none of the sleeve protruding out the bottom and making a step by not running the boring bar all the way out the bottom like we do straight barrel repair sleeves in damage v8 cylinders. Allis OEM sleeves protrude through . I just love commenting mind readers who knows my intentions

Well, then...won't you be happy when this POS he's building sucks all the sleeves into the crankcase and consumes his didn't really make it on his own crank. I swear, you guys need to go out back and settle this. I like reading about people who have the time, money, and talent to do stuff like this. That goes for WI50's builds and the one you worked on the last year or so. If every puller had the same thing it'd be like IROC in NASCAR. It's getting old watching people with talent, money, and time have their work shot down by others.
AaronSEIA P.S. Keep posting what you are accomplishing...both of you. |

Ml's eyes are clouded by jelousy. Again. I see a step around the top also and what looks like the top counterbore, barrel, bottom counterbore and relief on what hangs in the crankcase. |
