Hey all -- I've searched but didn't find a ton of info on this question.

I have these pistons:

And I'm looking to get these rods:

My question for you all is will I have alot of clearance problems with these rods? It's going to be a 355, forged GM crank.

I've heard alot of bad things about these rods in that department, so I thought i'd check before I went ahead and bought them.

If those are going to be too much trouble I was thinking of getting these:

Any opinions are welcome, I need all the advice I can get. Thanks!

 

Stock stroke crank, no problems.

Awesome. Thanks for the quick response!

 

You will have no problems with the eagle rods. Even in stroker applications they work great when the block is clearanced properly. Some people claim they have busted through to coolant on strokers with these rods. I have built many engines with these rods. No problems at all. Depending on your application, I would recommend upgrading to ARP 2000 rod bolts.

One of the complaints with these rods is the rod bolts are at a length to where proper clearencing is touch and go. Do the 2000 rod bolts have a shorter profile?
The shop that built my 396 broke into a water jacket and recommended CompStars. The block was replaced and they had no problems w/ clearencing. These and the Eagles (6") were put up side by said and there is about a .100 difference between the two rod bolt profiles w/ the ComStars being shorter of the two.

 

Yeah that was one of the things that made the compstar rod more attractive to me for my build.

 

Hes building a 355

Please read my question to proflowjake.

 

The ARP 2000 rod bolts do not have a lower profile. They require the same amount of clearance work as a 8740 or L-19. I pressure check every block after any clearance work is done to show if a cut is made to deep and into a coolant passage. I do agree that compstars are of a lower profile and they do require less clearance work. However, Buck for buck, Eagle is cheaper to build, therefore prices can be dropped without sacrificing engine reliability.A Compstar crank and rods can be upgraded for about $600-$700. But like I said, I have never had a problem with Eagle. It takes careful precise cuts with attention to detail. Doing clearancing work with H-Beams and a stroker takes alot more time than I beams and a stroker. Either a 383 or 396.

This is my opinion about these parts. Other may agree or disagree.

 

Appreciate the input.

 

I was told 6'' h beams wont fit with a standard base circle cam. Is that true? with a 3.75 stroke?

 

My L-19 rod bolts required clearencing. I have a 3.48 stroke crank (355).

I have pictures on my old comp, but some of the bolts required a good bit of clearencing to the block.

 

6" h-beams WILL clear a standard base circle cam in a stroker application. I beams will not clear a standard base circle cam without clearance work on the rods. Eagle now provides this service free of charge to all of there I beam rods so they will clear a standard base cams.

 

I too have a friend who had to clearence a 355 block on a ZZ4 engine of his.

 

What?! I just installed Eagle I-beams with no camshaft interference...maybe my cam wasn't "standard base circle".
