Yah, last year when I had questions Belfab was PROMPT with the reply and it was cockeyed hours. I haven't heard anything bad about their product or their company so I'm thinking they're the one's for me.

 

I had the same problem with my Eagle rods and Wiseco pistons.

The Wiseco pins worked just fine with the stock rods.

I don't buy the assertion that it's so they can be machined down. If that were the case then the crankshaft bore would also be too tight (they're not). The specs are in the factory manual and as long as the parts are strictly made to those specs, they should all fit together. If I wanted undersized bore holes that I have to machine out, I would have specified that. The rods are just made wrong.

Based on what I've heard about Eagle rod quality (from someone I know who's worked with and built scores if not hundreds of race engines: "it's crap"), I guess I shouldn't be surprised. I'm gonna give the M-Tuned or Belfab rods a try on my next build.

 

way to bring up dead thread!

anyways, that seems to be the problem with wiseco pistons, not rods.

 

As I said, the Wiseco pins worked just fine with the OEM rods, so I'm placing the blame on Eagle's end.

Not that Wiseco is perfect either. I'd rather not have to modify the oil squirters to keep the pistons from crashing into them.

 

Huh? I didn't have to modify my wiseco's (low compression)

 

The Wiseco pistons, at least the high-compression ones, hit the oil squirter nozzles near the bottom of the stroke. Most people cut the oil squirters or just delete them altogether.
