What's left of GOD's country, ...
Yup, you're right about these Arias pistons, made in the mid-70s but typical of the quality of that time period and a very similar Alcoa forging blank used by Venolia. Nonetheless, a pretty good piston considering and tons better than a high silicon/boat-anchor TRW-type. So, is there a 'set' dome configuration? Pin boss oiling, accumulator machining, etc? Thanks...wb

Just a heads up. Bobweight for the first engine with these flat tops. 2335G. Stock rods and stock steel crank.

Keep the comments coming guys.I am exploring all piston and rod configurations.I think you will be pleased when I have the finished product to show you.I want to cover the 383-400 stock config first.I will get to the stroker and long rod configs soon if folks are interested.



Mike,
any thoughts on the shorter stroker set-up lately? I'm jones'n for a piston for my 400/ 3.91 crank build here. Still looking around for a shelf piston that will get 10.5/1 up to 11/1 CR running a 78cc aluminum head. I'm first in line for the release of the Trickflow heads next month.

Update!


The first set should be ready in a couple weeks.I will post pics and specs with price then.Unlikely that this modern forging could be stock weight.But there may be a way to work that out.I am looking into that. Please continue comments and your ideas.




Any progress on this front? I have a customer with a 400 in my shop right now, scored a deal on re-built big valve 516 heads and he could probably be talked into the piston if it was not for the re-balance on top of it. Otherwise we will just buy cheap re-builder 440 .060 over pistons and deck the snot out of the block and be cheaper.

Chris, what con rod are you using? I don't think your set up will be an issue.

Dave, I haven't heard much on the heavy piston due to vacations. Everyone should be back this week. I doubt I can add enough weight to make them sealed power/trw stock forged pistons. I know how customers are and you can't please everyone. These are intended to be an upgrade not a replacement. Likely the 400 piston would save enough weight that the engine could be internally balanced. That should be a big plus for a 400 stock stroke owner. Steel 383 crank is now an option too.

BTW Owner of the first set is very pleased with his engine.

Yeah I know it seems kind of odd asking for a heavier piston but seems the only reason guys will build a 383 or 400 is to save $$$.

I do have a few steel cranks sitting around I could throw one in his motor.

Having built both 383s and 440s in the past, I'd never build another stock-stroke 383 that required "good" pistons. If I had to spend the $$$ for anything beyond stock-type parts for one, it would be getting at least a 3.75"-stroke crank, too.



Good luck to the OP w/ this effort, but I believe my original post from "way back when" is still valid.

9.5-1 can be reached,depending on bore size with a closed chamber cyl hd @80cc's. 5 to 7 cc dome (off the top of my head )would allow 10.5-1.That is a very small dome that I have used before (Ross) 4.280 bore 0 [Email]deck@9.968[/Email] with 84 cc Eddies and 5 cc dome 10.7-1 .040 quench.





Curious what calculator you use , I have a 383 with a piston at zero , 3cc valve reliefs, steel shim head gasket and 80 cc heads and I'm just over 10 , I think 10.2 ?

Chris, the piston you seek should be readily available shelf stock 4.375 bore, 1.32CH with a 5cc valve relief at zero deck and a std. .041 head gasket will get you 11.12

Hi all, for a reason unknown to me my supplier has changed my deal and they have cut out most of the free options.I am now searching for another supplier. However this piston is available now.Piston will be the following a flat top,1/16 rings,CD of your choice,symmetrical valve reliefs and overbore size of .030-.040-.060.Sorry guys compression ratio will have to be modified by the cc's of the cyl head.I see that will be the only way to keep the price down. Thanks for all your support,Mike

I would like to see a piston at +.020... I try not to have to go straight to +.030 unless I have to.

Chris,I now believe +.020 will be the first oversize. I want to keep the asymmetrical valve reliefs and therefore I have to drop an option. I think that will be the adjustable Comp dist. As of now the standard piston will be the following:

Bore size 4.25 +.020,030,040,060. or 4.375 for 400 block.
Ring pack 1/16 1/16 /3/16
Comp dist 1.930
Asymmetrical valves reliefs or flat top w/o reliefs.

So, any updates here? Where do we find these pistons?

Hi, pistons are available from me. Only change is the valve reliefs. As of now only symetrical valve reliefs will be available.As shown in the pics posted here.Thanks,Mike

I'll be looking for replacements for 68-69 HP pistons.

Ideally I'll be looking for the following:

- 1.932" Compression Distance
- Flat Top w/NO valve reliefs
- 4032 alloy
- 1.094 pin
- 1/16 1/16 3/16 ring size
-.+030 oversize

Can I get these through you? What would they cost?

Reality of manufacturing today is you have to compromise. I wanted to make a true 9.5-1 comp easy to get to.(pump gas) Some blocks are a bit short on deck height therefore the 1.920 comp distance. Valve notches are one item that was missing from the old standard sealed power/trw slugs.Must folks want that so they are included.I can not make every combo at this price.Overall I believe I chose the best options.The set up for comp can be tuned in with deck height and cyl hd cc's.Thanks for your interest.


Btw if anyone is interested just email me or message me here on Moparts
