Can Anyone advise from experience I have a set of eagle H beams for a stroker 451 project that the machine shop bored out the 9.90 bushings to 1.094 Is this safe to run? are there any reasons why i should not?
Thanks

The first question is why are you building a stroker with that short rod ? Part of the advantage of the stroker is shorter pistons so the engine revs faster.

That said , how much material is left on the rod without the bushing and how much did he remove ?

I am confused by your post.
What is the rod journal size for your rods?
Did he press out the old bushing, enlarge the hole and press in a new bushing? Or did he bore the existing bushing to the new size? Is there any bushing in the rod right now?
Are you intending to use floating pins or pressed pins?
Are you sure the rod is 6.358? A 0.250 longer bigblock chevy rod is 6.385, pretty common for use in 3.75" stroke B strokers.
The selection of aftermarket 6.358 rods is pretty slim. However, 6.385 rods are falling out of trees right and left.

427 chevy engines worked pretty well with a 6.135" rod and a 3.76" stroke. 400 chevy enginescame with a 5.565" rod and a 3.75" stroke and seem to run really well with a 5.7" rod on a 3.75" stroke. So a 6.358 or 6.385" rod on a 3.75" stroke looks pretty good from here. Even on a 3.91" stoke it looks pretty good.

I have given up my "long rod religion"
as I'm not building or dreaming NASCAR engines. I'm sorry, Smokey.

Eagle sells the 6.358 with a .990 pin , it's pretty much useless for any lowdeck mopar application because there isn't but one or 2 pistons that are setup for floating pins , and maybe only one that is a .990 floating pin.

Low decks get little love , there isn't a magnitude of shelf stock pistons for the many possible stroke/rod combos available unless you go to a custom or semi custom piston.

Really. I looked in their online catalog this morning and couldn't find any 6.358" rod. However, it wouldn't be the first time that an online catalog was missing something.

They may have discontinued them because they don't get used much .

Well its a long story but it turns out it was the only way to use a set of 800 dollars set of ross full floating pistons that i had on the shelf from a mistake made on a stroker kit that i had to re order the pistons because some one orderd .990 pins and 1.094 custom pistons.

So instead of 8 Christmas presents for my buddies as ash trays , I don't think i have 8 buddies who smoke lol.
I figured out a 1.73 comp height with 3.75 crank i had sitting on the shelf.
Would fit into a 50k mile 400 block that i had by honing it to size .010 over i could make 450 cubes with the .030 rb pistons laying around with stock 6.358 rod length. the combo works out pretty close to zero deck.
I could not find them on the internet either but i found these today

This is the part i have it just looks like the bushing for the rod is pretty thin, that is why i am concerned i thought the machine shop bored the .990 pins hole to fit 1.094. but since i did find a set i guess they make um..... but worried about durability!

Gotcha and I know how it is to have a set of custom $1000 paperweights that you need to make work I can't remember if the eagles I have in my 383 are .990 or .1094 , I'd would think the rod blanks are the same and the finish hole size is different depending on the bushing. If the guy that did the rods just honed it out to 1.094 did it so it was either a press fit or to floating without a bushing you should be fine .
