Anyone have reasonable price 426 wedge pistons 030? Where to get some at that won't break the bank?lol

Max wedge or street wedge? What compression ratio are you wanting?
Either one will not be easy and cheap

It's a street wedge block Hughes and Campbell want to much for pistons.probably 10:1 compression don't want to run race fuel.

I think they buy and have bought up a lot of old warehouse stock from the 60's and possibly other eras. I often find that they have what I need. I bought a set of NOS TRW forged pistons for my poly 318 and found that they had several different sets in various over-bores. There are also a few M/W sites that may be helpful if you haven't already checked.

Do you have the heads you want to run?

They only have one 426 wedge piston l seen.

I would have your block sonic tested to see how thick both the thrust surfaces are, if they are all .180 or thicker and at least .120 thick after boring on the front and back sides of all cylinder walls you could think about boring it to 4.320, which is the standard 440 bore size
What year was your block cast in? Is it a street wedge casting or or is it a 1964 M.W. casting used in a 1964 or early 1965 street car build with the smaller heads and oil pan pickup?
As far as compression ratio and iron heads I would not put more than 9.5 to 1 compression ratio in it max Pump gas is not going to get better, is it

It's a 64 426 street wedge block,not tryin to run race fuel in it.

There are a lot more choices on 440 standard pistons than 426 street wedges, correct?
I would order a set of standard 440 350 HP 1968 to 1971 pistons

If you want to build a 426W then you have to buy semi-custom pistons.

Yah l see that wondering if anyone would chime in on here first seein if they would any.seen ads on the past sayin someone has pistons they have and sell.

No one at all has any layin around?

Try Egge? By the way, need a manifold?

Tried egge,they have to custom make he said

I have a fresh street wedge block with pistons matched. The pistons were originally high ratio Maxwedge but had the domes cut to low ratio height with the plans to run as a stocker back in the early 90’s. Been bagged ever since.

.030”, bored and honed with plates, parallel decked for clean up only, fresh cam bearings, was baked and blasted.
Has the A stamp on the pad - 1965.

Won’t separate the pistons.

You should sell it l know someone would want it and build it.

Try Diamond?

Put an ad on the HAMB. Also try classracer.com

Oh ok I'll try them

BMJW

The engine would have no hp with a 8:1 compression if l did that.l could bore it to a 440 and use standard 440 pistons which be The same price as those low compression 383 pistons are. Mise well bore to a 440 then get another crank it be about the same price.

I used Diamond pistons in my 426W. Made a little over 600 hp on the dyno with a mild hyd roller cam and Trick Flow 240 heads.

Very interesting aF ...

More info please !

That's sick what was the cost of them? Do you still have your 426 wedge specs when you had them made custom?

Probably less $$ than 383 pistons and a stroker crank and then you also get lighter pistons with decent compression, better rings and valve notches.

Either put 426 wedge pistons in or bore it 070 for standard 440 pistons.l rather just try and get 426 wedge pistons first.

I've had to bore several 426 blocks, both street and M.W. blocks to 4.320 and used 440 pistons in them due to to much taper in the 4.310 bores, no problems on any of them
I did have them all sonic tested first though boring them larger
As far as strokers and lighters pistons compare to the stock stroke RB pistons weight the longer the stroke and the longer the rod the lighter the pistons get
Can you say 526 grams with the pins

I don't recall, I'd have to look it up. The billet valve covers probably cost more than the pistons. It wasn't a cheap build.

Oh ok lmk if you find your specs at least,badass 426 wedge you built

Good to know thanks for more info on boring to a 440 if l do that.

A friend of mine has some .075 over flat top ones. $250

There a 426 wedge with a 075 bore or a 440 piston? Pm sent

Still lookin for all options and sizes available others may have before l make choice on what to do.

Do tell, CH? That must have been a light as hell pin

Hi All,

A true 426ci engine is a 4.252 bore.

If you go 0.062 over, it will be a 438ci engine...

Doesn't quite have the same ring to it?

A 426 wedge is a little different then 426 hemi

DWTFYW.

I rather you use the 426 stock crank then get another one.ld rather not use 383 pistons either

I faintly remember someone, years ago, who tried using oversize 383 pistons in a 426 wedge and they were either way to low or high in relation to the deck to be used The compression heights, deck heights, stroke and rod lengths are different on them

What I though 383 pistons won't work that well.

Time you get that crank and pistons you can get custom pistons for about same the crank would cost.that be a stupid way to go as well.

True, if you don't want the extra 40+ cubic inches and 50 lb-ft of torque. Why get 478 CID instead of 431? Spend $1200 on a set of Diamonds instead. Your engine and money. Do WTFYW.

I have 3 leads on new old stock 426 wedge pistons.much cheaper then custom ones to. If your not payin to do that my block.keep your mouth shut then,ill do what i want to it. I came here to look for 426 WEDGE PISTONS.not oh use 383 pistons which will give it 8:1 compression.there so down in the hole on cylinder walls.i bore to a 440 if went that way &cheaper then using 383 pistons route.

I get 383 pistons will work but no one has any 426 wedge pistons on here they would sell?

I have a set of 8 TRW pistons for a 426 wedge. They are used with about 3,000 miles on them. The part number is 2185F and they are 030 over. These were in one of my motors back in the early seventies. One of the rods spun a bearing and I had the connecting rod removed so I could replace it. I ended up getting a great deal on a 440 Six Pack motor and put the pistons aside. They are in my storage and I'll look for them in the next few days. I do not remember what the compression ratio of these are.

Oh ok cool Im interested in them.lmk when you find them.

Some CP Stocker pistons.

Arent they a 075 over pistons?

Only +.005" on my standard bore 440 block. I think it can be honed out to fit the pistons. Not sure which CP pistons they are. Al said there were no numbers stamped in the tops, like M14, etc. New stocker rings will cost a lot more than the pistons.

Not lookin for a big bore pistons,030 would be good

Have found some 426 wedge pistons old school mickey pistons ones brand new but they take a .984 wirst pin, which is the small block wirst pin size, what kind of pin or bushing to make them work with a big block stock rods?

Options ? ... bore the pin hole ... or bush the rods

You can bush rods form a 1.904 to a .984?

You can't make them work with those pins safely
Maybe you can have the pistons converted, machined, for stock BB pins

1.904

That's the stock size of a wirst pin for a big block mopar engine

Better check aGaIn ....

Couldnt they be machined to a .990 wirst pin size? Not much from a .984 then l could get reducer bushings or rods for the .990 size

Try calling both Jahns, if they are still in business and or Ross pistons and see if they will remachine the wrist pin hole in those old M/T pistons for you.
Mickey Thompson always had vendors make his parts, he didn't own the company that made them for him,
Maybe even try Crower on fixing them for you

Oh ok I can try and call a few piston shops up.jahns is called je pistons now

[quote=jahns is called je pistons now [/quote]
I was not aware of that, thanks for sharing
They were one of the few piston company I can remember from the early 1960 when I first got into hot rodding and drag racing. I'm sure there were others making them like SilvoLite, badger and so on.
SRP is a sister company to JE for street use, they are on the same web site, I was told that years ago that the Calvert Bros, not John Calvert the drag racer, I don't think he is related to them, sold JE and had a 5 year no compete contract.
They later bought out Carrillo Rods and started CP pistons after getting back into the hot rod market several years back
Good luck on your deal

Oh l see thanks if can find some bushings for rods or get some custom made that be better won't have to mess with piston wirst holes at all. If l get end up gettin the pistons

Someone offer me some L2185 426 max wedge pistons. Anyone know anything about the old L2185 pistons?

They are high ratio. I think 12.5, I think the 2184 is 11.5 to 1.

Ok how would you reduce the compression down on them? Like a 10:1

First you need to calculate what the ratio would be now.

What is the deck height, chamber volume, bore and stoke.
Then plug in the dome volume.

Thick gasket may be enough or may need to whack the dome.

There you go Tman ...

How about initially a pic of the dome .. then that spec

Then the compression distance

4-1/4 5/64,5/64,3/16 13.56:1 2.3765comp. That's what it's says the compression is for the L2185

Ended up gettin those pistons got for a good deal way cheaper then customs.there the 426 max wedge L2185 425hp pistons. There ways l could get the 10:1 with those.

I got those pistons from Al Corda. CP stock eliminator pistons. .043" top and second rings with spacers to fill up the 5/64ths ring groove (NHRA requires stock groove widths). 760g piston, 144g pin (about one inch shorter than the stock pins and maybe 50g lighter). They are flat tops but the forging has material for valve notches that could be added. 2.031" compression height. I think it would be around 10.8:1 at the NHRA specs for Stock. Larry Hill has some older stocker cams he ran, but he didn't think they would work with the flat top pistons. I think he is running the 440-6 combo in his Cuda. I have an interest in Stock Eliminator engines and cars. My 440 could be built into the 426-4 combo with a smaller lift cam and the small AFB (3611S) and 516 heads. Not sure about bothering with that.

Good luck with your build. I'd like to see the domes on them as well.

I wasn't goin to bore my block that much those were like a 75 over pistons he had.thats good you got them from him and will use them.good luck with yours to

Anyone have any good used 413 426 max wedge piston rods? I know can get regular 440 rods

Which casting number rods do you want, 1962 413 or 1963 426 M.W. or 1964 M.W. rods?
Some of the 1962 and early 1963 M.W. rods used the same casting numbers, I'm not sure of the exact date they switch to the 1963 M.W. casting date

Casting # 2406886 or 2406395 max wedge 426 rods. 413 would work to

i may have a set of 62-63 413 rods that start with the casting # 185xxxx on the shelf. they have junk flat top pistons on them.
i'll check later this afternoon and report back.

Oh ok the 185 are the standard ly rods which were on all rb like 440 413 and 426 street wedge.

yes, these are LY rods. you probably have some laying in the corner somewhere.

just trying to find a home for these, as i will never use them in this lifetime...........
they came with a 62 MAX top end [heads, intake, carbs, linkage and exhaust manifolds] i got years ago. at that time, i looked up the 185 number in the "white" book, and it stated 62 413. i noticed at that time they were LY rods, but i didn't have any other LY's to compare them to.

I could be possibly interested in them,if that is all you have are those.

if so, pm me with an offer. i'm sure we can work something out.
i can take pics of them and send to you if i can get your e-mail.

Ok pm my email

I have a set of NOS Arias flat top 440 pistons, I think std.bore,if interested Ill get more info on them.

Lookin for rods not pistons anymore.l found some old trw L2185 ones l just recently got.

pm received. i'll get some pics late this afternoon & send.

Oh ok sounds good

Received the pistons

Congrats on landing some pistons for your build. Thanks for the photo as well. Is the 809 on the one piston the weight in grams?

Not sure what 809 means,could be

Anyone know the cast iron thickness of a 426 wedge block? Like the outside thickness of block?

They vary depending on which year and type, M.W. or street 426
I've never sonic tested the outside but I do know of some old time SO CA class racers that had the outsides machine thinner to be able to put more weight in the trunk and in the gas tanks
I'm pretty sure that they are not real thick, maybe between .160 to .220 depending again on where on the block your measuring and the how many times that sand casting mold had been used before that block was cast

It's a 64 block crack is around freeze plug area.

You have two choices on fixing that, take it to a cast iron welding shop or have it "drilled and stitched pinned "
I had a 1965 street wedge block that had two freeze cracks and a casting flaw in the crankshaft area at the bottom of cylinder #4 that leaked coolant that I had fixed at a cast iron welding shop in SO CA. The owner wanted that block fixed instead of using a 440 block he had due to it was the proper casting number and casting date for a 1965 Plymouth Satellite he had
I've heard that there are some new cast iron welding rod that any good welder can use now to fix cast iron cracks like your deal, but be careful on who you have try that
I've had several freeze cracked 906 heads fix the other way also, all things are fixable, not cheaply though
Good luck on your deal

Well im goin to try and get the cast iron welding rod to fix it through muggy weld and stick weld it with rod.or get that lock n stitch kit.they need know to the thickness of block cast iron on block.so they can send me the right kit.would you know the thickness anyone?

Try using a one inch mic through the core plug opening.

I have a Dakota 1000 sonic tester that I use to test cast iron and aluminum as well as other metals.
I've seen a cylinder wall vary .050 about in a area about 1.0 inch circle on the same side of that cylinder
My message is each block will be different in different areas, they are not precise castings
