383duster

383duster

they say I'm a sheep forker.......
took the 383 apart and the rings lost their tension, i also need bearrings but i got them in stock at home.
this block just have too run for halve a year so i can finish the stroker so i'm not gonna rebuild it.

So who want's to drive to a parts store to buy file fit stock bore 383 rings for me and send them to Hollamd for me??

I will pay your time no problem i just need rings in a few days so that i can assemble the engine in a week or so.

please [smilie=e:

I will love you forever!! [smilie=e:
 
Is there any American V8 that used a 4.195" or 4.200", 4.215", or 4.225" bore from the factory? The reason I ask is because a set of file-fit rings will be quite expensive... but they're essentially a .005" oversize ring in most cases. If you can use a set of .060", .040", or .030" oversize rings from another engine they should be inexpensive, and work as file-fit for the 4.25" bore.

As an example, I wanted "file-fit" rings for my stock-bore 318 (3.91") but didn't want to drop $130 for 'em. A little research showed that a set of .040"-over rings for a 283 Chevy (stock 3.875" bore) were 3.915" in diameter. Perfect, and a set of moly-coated ductile-iron rings set me back about $45. Since literally all modern American V8s (almost all since the '50s) use a factory 5/64", 5/64", 3/16" ring stack (top/2nd/oil, by thickness), this sort of ring juggling is commonplace in esoteric combinations.

So, I saved almost $90 on the essentially the same set of rings. I'll look into a set of file-fit rings @ work on Sunday if I get a chance, but if anyone knows of a stock bore as listed above, I'll see what I can do on the cheap.
 
Big block Chevy 427, 454, and 496 are all 4.250 bore.

366T = 3.935" x 3.76"
396 = 4.096" x 3.76"
402 = 4.125" x 3.76"
427 = 4.250" x 3.76"
427T = 4.250" x 3.76"
454 = 4.250" x 4.00"
496 = 4.250" x 4.37" (2001 Vortec 8100, 8.1 liter)
502 = 4.466" x 4.00"
572T = 4.560" x 4.375" (2003 "ZZ572" crate motors)

T = Tall Deck

4.195" - AMC 390 + 0.030" over

Also check 400 small block Chevy.

Do they make a .090"-over ring for it? We need to get to 4.255" here...

Dunno. Just going by what I found in my Google search. 4.200" showed up as a popular 400 small block Chev size.
 
how about a set 0.020 383 rings? can i file them to fit?

otherwise just a set of stock bore rings would be good, always better then these 38!! year old factory rings IMO
 
As long as they're not .020"-over and you're filing them... way, way too much ring tension there.

Then again, it's only got to last how long? :D Even so, I'm thinking usable virgin 383 blocks can't be easy to find over there.
 
no i'm getting stock bore rings, and 383 blocks are enough here, i got 3 at the moment, everybody wants 440's so the 383's are cheap [smilie=a:

i think i got the new stroker (383" to 450") complete in halve a year, only need heads, rods and the block must be prepped, but i bought a car so i gotta save some money first [smilie=e:

this block is in very nice shape for it's 38 years old but i will put new rings, bearrings and gaskets in it so it's running good and not leaking

thanks anyway! [smilie=a:
