You could get the crank and pistons for less than 1900 and have a 580"

.020 is largest listed shelf size. You'd have to call about the extra .010. I wouldn't think that will be an extra 1000$

Agree, the blank starts out large, turned down to size one needs. Never thought it would be this much problem. Thanks you been a great help.

What is the condition of the bores? Finished honed and straight?

Yes good finish and straight, my concern when looking for pistons from the big engine builders, they said they never go over standard (4.5) because when bored there’s not enough material left between the cylinders = blown head gasket. I guess they made throw away blocks. Then the other can of worms is if all 8 holes are sleeved how weak-thin will cylinders be then (Siamese block) I feel like I’m in no mans land. I have everything there for this engine waiting now in limbo. One other thought, can standard pistons be coated .030?


Call Line2Line on coatings - max thickness, etc.

Their website says thicknesses up to .020”.

Just checking one of the ten sleeves from an aluminum block. It mice out at 4.528 and slides in till the top 1.25 step. With the loctite will that be too loose? The rest are bigger on the outside but 4.28 bore. btw these are some strong steel not cast.

In my opinion yes, you need some interference to transfer the heat. but your on the right track. You need the step to secure it.

I should have said if it slides in its not enough.

If the bore is 4.530...dead nuts. you need at least 4.5305. Nothing is perfectly round to the tenths.

Fixed bore number......

A friend has a boring bar and the good sunen hone. I could then bore it with the step 1” from bottom. Then turn sleeves to .005 over that. Got a plan

Yes, EXCEPT Ikeep fudging up the numbers You should be 5 tenths over, not hundredths. I should have typed 4.5305. I have habit of not proof reading..until I read your response at.005.

I would be putting the step at the top not at the bottom if you are staying close or at your 4.53 step at the bottom, bore needs to be 4.63 our more to leave a substantial enough step.

There’s a set of 4.60 (another .035 off each wall) (time to sonic those walls I guess) pistons on flea bay cheap but I’m afraid to bore that big, sealing on deck between cylinders and wall thickness. Maybe o-ring with copper gasket would hold.
