Hello all,
I'm looking at piecing together an 11:1 331. I may have a crank lined up, now I'm looking at rods and pistons/rings. Here's the info I have on the crank.
331 sbf cast nodular iron stroker crank

- 28 0z. balance
- 2.249" main journal
- 2.100" chevy rod journal
- 3.25" stroke
- Recommended for 5.400" length rod

I'm not really looking to put more than 450 (max) through this thing, no power adder.

Can anyone make any recomendations? Not looking for any billet forged H beams or anything of the like. I'm not going to overbuild this thing.

Thanks,
Mike

not ease /common to be CHEAP for the 5.400 length with a 2.100 bearing diameter...

when parts are deemed CHEAP,

you also give up a lot of strength and durability.





TOO CHEAP OFTENTIMES ENDS UP COSTING YOU MORE.

I never said anywhere that I wanted to go cheap.

Is the 2.1 diameter going to be the issue here limiting me.

Can anyone make a recommendation on a street oriented connecting rod?

99% of all 5.400 rods will have a 2.123 rod journal, the windsor rods like the 6.200-6.250 are chevy rods to begin with so they all use 2.100 journals, you wont find a 4.00 inch windsor crank with a stock ford 2.311 rod journal. The cheapest rod for you will more than likely be an eagle sir I beam, but check the width of the crank journals versus the width of the eagle rod. Eagle uses all 2.100 on there rods.

said because you have employed the term...." I am not going to over build this thing"...

price / cost is directly proportional to durability and life...


there are a number of makers of 5.400 X 2.100 bearing/.927 rods.....

it is a chevy based part.

eagle
scat
probe
along with other marketeers that put their name on it even though they do not MAKE it,

...all have the same dimension part available.


look in the BOOK...!!!

high end for high stress of power output is generally considered being from:

carrillo
crower
oliver
cunningham
ETC.


once again,

you opened this topic with the words ..." BUDGET MINDED".....

./..and then it all has to be balanced with the flywheel and dampener....



I still do not think that you will be saving much if any over a pre fitted KIT....


but it will be a learning experience none the less...

I'm happy with the forged Scat 5.4" rods (w/full-floating wrist pins and cap-screw rod bolts) in my 331. I'm confidant other things will fail before the rods do, although I'm not pushing quite as much power as you want to.

You are looking to buy 8 of those rods for your application...seems like overkill;)
Ha, I didn't realize those were each! I was looking at set's , don't know how those made it in the search.

details..


and this is out of my HEAD...

research out of my head from memory...


the cast cranks from some actually employ a 2.100 journal BUT
they use a ford specific WIDTH...
a ford Width is narrower than a chevy width....

so, that is not a common chevy rod width insert nor rod itself..


as you SAID,

it is only RESEARCH..

you better ACTUALLY MEASURE.....

a CHEAP price on the crank could also mean that you have to use a odd conn rod width and rod bearing insert...














I hope for your sake that it is not one of them POS hawk or TMD reject cranks that you have such a deal on....!!!!!
or even one of them RMP rejects that flood the internet with gobs of advertising....!!!

nuthin' fits nuthin..

and some of them will not balance at all with common weifght of parts...!!!


it is all just research.

as stated before, I doubt that you will actually end up saving any money after all the trouble and various fitment / remachining and balancing that you will end up having to do in comparison to have just called on phone and ordered a pre fitted and pre balanced complete KIT....
