I'm with the "Ace" on this one.

Scat I-beams get my nod over rebuilding a stock rod every time.

-Mindgame

 

[QUOTE=Kain]I retract my earlier statement. You might want to consider at least 36#'ers. I've got 30#, and I'm moving up to 42#'ers, LE3 heads and LE3 cam, and a 58mm TB.

Those are some nice numbers.
How high do you spin that with your set up?

How soon are you looking to move up and are you going to be selling your LE2 and 306 cam set up?

I need that same set up right now

 

You would take the stock rods over Eagle I Beams?? Why so, I dont see anything better about the stock rods than an aftermarket forged rod...

With that being said, I am using Eagle forged rods, stock crank and srp pistons. I have spun my motor over 7k many a times, it only has 2000 miles on the engine and about 500 of it are hard miles.

So your combo will do what you want.

I am running LE2 GM847 with 30 svo injectors, I dont see anything past 60% duty cycle.

 

I trhought the rod in question was the "SIR" I-beam rod, which is a 5140 rod. The ones I have seen didn't look very good. Bolts are 160,000psi ARP, which aren't bad but are about as basic as you can get. Can't say I thoroughly inspected them, but a set of stock rods with upgraded bolts seems more attractive to my eyes.

Nothing wrong with the Eagle H-beam other than the poor stroker clearance, and IMO, the country of origin. I think you can do better than the H-beams for not much more $$$ though.

i think what is trying to be said, is you can use a set of 95+ stock rods with some new ARP's for dirt cheap and since he's only doing an LE2 package and probably some spray the rods should hold fine. if he's planning on doing more later on, then i'd suggest just upgrading to forged rods now. but for the setup he listed, stock rods would work fine for a fraction of the cost.

 

Rich,

I do agree the made in China is the worst part.... the 5140 steel is not that bad at all, still stronger than OE, and ARP 8740 bolts are up to the task for what these guys want to do with them. Polish the beams on these rods and you are ready to rock. I still just have a problem reconditioning stock rods, too much work there for me.

Mean keeps mentioning 95+ rods, but wasnt 94 the first year for those rods? and it was only 93 that had the "pink" rods? i have a 94 and would like to know just how much the stock crank and rods (mine) can handle.

 

I hate throwing out usable stuff. I have a house full of antique (= old) furniture and recycled (ex-stray) pets. My "real" job is making broke things (people) whole. So, I hate to throw out a set of decent rods. I kind of look at motors like hammers, replace the head or the handle as needed and they may last forever!

The 94 engine had GM forged rods. I don't know if all of them did but a lot did.
My engine class instructor thought they were very good rods when given ARP bolts.

He was very suprised to see that you can get Eagle I beams for $200

The Eagle H beams I see for about $325.oo Which rod is close to that price?? (Just curious for future parts)

I would much rather buy a American part but the Eagle stuff is cheap and the H beams seem to be Very good quality. Now that I've had a problem with clearancing my block I would have rather spent $700 for rods that didn't cause me any problems

 

You must hate the "disposable everything" mentality in medicine. It does keep the hardware makers busy, though.

'Rescued' pets rule! Well, canines, anyway.

My take on metal parts that see cyclic loads, like rods, cranks, etc. is to remember that metal, much like a woman, remembers EVERY stress that was ever imposed upon it. When it reaches it's limit, it/she goes BOOM, sometimes with no warning, and not necessarily during a time of peak stress. The preventative medicine is to trade in on a new part. That's usually easier (cheaper) to do with engines than with ladies.

 

Beautiful analogy Stroker, its oh so true

 

i better do some preventive maintenence....any idea where i can trade my girl for a newer one? they have a dealership or something for that?

 

Your local high school, perhaps? At my age it's the local adult care home.

 

Thanks. I had some really good teachers and mentors back in the good old 60s muscle car era. I was fortunate to work with the folks who invented the concept. ('61-'68 @ Pontiac Product Engineering). Some of those guys, who's names are familiar, were very bright. More so than I probably realized at the time.

The current "brightest star" I know works for a major cam company. Awesome knowledge of how the world works. Big brain, small ego. Just the opposite of the "Big Watch Syndrome." We probably shouldn't go there....
