Short Block Advice

Broke 4 pistons in exactly the same spot. JEs with 5.7 rods.

Oh yeah, that was the first day out racin' too.

A painful memory that I'm just now recovering from. I can talk about it now.

I think you'll find those are forged Wiseco pistons, thats what it looks like. I am not a fan of their piston design for the very reason your pic shows. They get real thin right there on the edge, good spot for failure, did you get some severe detonation? You will probably be able to reuse the rods if they are indeed Crower sportsmans. Jcamper

Those indeed are wiseco pistons. However if the motor is running properly they wouldn't have failed. That indeed is from detonation. Just because they broke doesn't mean that they are week. I've broke factory pistons in the same fashion due to detonation.

Once the motor is back together he needs to make sure it is tuned properly. Does the OP have a wideband O2?

I broke a Diamond piston within 100 miles with 5.7 rods. Definately not the way to go on a turbo engine.

Nevermind; wrong person.

My bad.

JEs with 5.7 rods.

That was the Ford engine rejecting a Chevy part due to the transplant.

Man, I'm just a newbie. Had no idea.

I'm getting ready to order pistons and rods. Is this a common failure regardless of brand (Wiseco, JE, other)? Or is this a Wiseco specific piston failure?

It's more of how you build your short block. Rod length dictates piston design.

[svofloyd]

Not to thread jack, but on the discussion of rod length's, I've seen 5.5" rods and matching weisco pistons from racer walsh. Anyone have any experience with those, compaired to the 5.7's? I was told that the 5.5rod/piston combo consumed less oil, and was more streetable. Just a bit curious.

[svofloyd]

wow, fast on that post. Like em? How's it run? I would really like to know. Worth the money? I have a 92 ranger 2.3 sitting out(smaller mains) i was thinking about building w/ 5.5's but i wasn't sure. But then i was thinking i may as well go big, and pull a 2.5(to get the edis stuff since i'd go ms) from the scrap yard, and do it big. Then my wallet had a disagreement with me. so it's all still speculation. I hate being poor.

[svofloyd]

I would say. That price list for it is a bit high. just curious but how much of a mod list are we talking?
