Technical Any piston manufacturer make a non standard wrist pin hole height?

Any ideas who to contact?
Trying to keep from machining a block.
Long old back story, I won’t go into it here, but paying for custom pistons (maybe) may be a better option for me.
Thanks.

 

What’s going on,,,,,tell me what you have in mind .

. Will shoot you a message. I’d rather embarrass myself direct than in an open forum!

 

If it is a block milled too far you can get a thick gasker. Quench distance not a factor if piston rises above deck

 

Oh, c'mon! You opened this can of worms. It wouldn't be the first time you've done something embarrassing on here.

 

@Justin Arias is on here… I heard a rumor his family‘s been involved in making pistons for quite a while…

 

I will try, again try, to copy my message to Tommy and send to you. I’ll also send you some loud ring chime thing to alert you and keep you awake while reading the message.
Yes, I look out for folks

 

Wouldn’t it be easier to re-bush the connecting rod?

 

Oh, let me explain a bit(and not be wordy). I want a higher compression height than standard.

 

I used Ross on a build. They'll do just about anything feasible. Not cheap though.

 

My experience says that when all is said and done it is easier - and cheaper, in the long run - to order a custom piston from one of the major piston suppliers. There are things in an off-the-shelf piston that may not really be optimum, like the antiquated ring package, the material, the pin offset, the land placement, the compression distance, the valve pockets, etc. that will be a compromise to the best working piston. Have I cobbled together engines using old pistons for a different application? Sure, but that was when my project cars were built on a budget as quickly as possible. Nowadays I like to take more time to try to get everything as right as can be. Including pistons

Try Diamond, in Detroit

 

Diamond, Ross and Weisco will be willing to build what you need. Just be prepared to pay up!

There might be.
I gotta find the ot thread, but some sharpie found out a name piston mfgr would alter std pistons for cheap - like $5.00 per alter. These were sbc 4" used in an acvw, but still. Cost of modding was decent, & pistons weren't stupid $$$ either. Trick was off the shelf types that could/would be cut to size anyhow. Essentially, what you ended up w/is a customized off-the-shelf for a few buck more.
I'll look for the mfgr. Don't know if they still do this, but don't see why not.

From what I have seen on this Forum most guys will understand you need a little bit of help and you therefore have no reason to feel embarrassed.

Hey, B36;
Found it.

Post #93, 96, 102, 115. Contact info in thread.
Piston co is(was) JE. Thread was from a few years ago, I'm sure prices have gone up since, but still...
Among the reasons for this, was altering compression height - same as you.
I haven't called to verify, as I don't need them. Yet. Hope this is working yet, & works for you.

Thanks Marcus.

 

You ve not mentioned the engine type or distance you need but a different rod maybe another option. As may a high compression piston and mill the top.

 

I wish somebody would come out with chevy 302 pistons and a 3.00 inch stroke crank.....

 

You didn't give much info about what engine, but it may not require what you would call a custom piston. Many pistons are out there as standard offerings. Just as an example the standard catalog Kieth Black forged pistons I recently bought for a project came standard with a compression height 0.008" higher than stock.

 

Hey, B36;
Here is another contact. Extensive line, one way or another, they do have a custom shop, don't know if they do inexpensive "off-the-shelf-alterations". They do make good stuff.
A lot of high-end pistons are made from 2618, another good alloy is 4032. Good reasons for both.
copied from another site, quoting Trevor:
ICON:
United Engine and Machine who makes ICON, KB, Silvo-lite and Dualoy pistons
UEM 1-800-648-7970, Just ask for Trevor.
Shoot me a line I would be happy to quote ya. 1-800-648-7970 extension 114

Cheaper than custom pistons

 

Custom forgings mean just that, custom. You get to choose every aspect of the design. Cost is relative to what else could be done, or not done, to achieve your goals. Which engine is in question?

Okay, SBC 350. I’m going to verify something on it today. Originally I thought I had a .001/2 ridge. I brushed honed the bores. An extra night shift at work zapped my desire to put it back together.
Yesterday I un-bagged it, I could not feel any ridge on any holes.
Back story-I purchased 72 cc heads with the plan to deck the block and run a .041 head gasket to get the static CR up.
Then I started thinking (usually a bad thing) a piston with more compression height would keep the material on the block, and accomplish the same thing (as mentioned a longer rod would as well-I didn’t think of that).
So today I’m going to hunt up the rod bearings I have, check 4 corners for squareness and critique the top of the bores with my bore gauge.

 

Good place to start! Also check deck height at the corners.

 

There’s so many piston options out there for a SBC you should be able to get one the right height out of a catalogue.

 

Don’t worry everybody,,,,he has a grip on it .
Mike,,,( budget36),,,,has a good plan,,,I’m certain he can get it all in order .
He is just trying to make an adjustment to the CR to match his head chambers CCs .
That’s a simplified post from me,,,,,it’s not a racing engine,,,,but a really nice hot street engine .
I’ll leave the details to him to disclose if he chooses .

You trying to get me banned?

lol.
As Tommy mentioned, this isn’t a race engine, but shooting for a very efficient 280/300 honest engine HP at 5200/5300 RPM.
Then her rev limiter will kick in, and I’m not going to tell her how to defeat it

 

I get my custom stuff from Ross.
