Not really a question I just wanted to share some information. A while ago I built an engine for myself using left over parts from my old mans bracket car. I had a 4.150 stroke RB crank that I had welded and repaired. I had four used eagle h beam rods. I posted an ad in the wanted section and a nice fellow sold me three used rods to match mine. I ordered one new rod from Eagle to complete the set. I also still had a nice set of pre tested (used)JE dome pistons. I toped it off with a set of stage 6 heads that I built right after I bought my flow bench. Long story short the engine in my fathers car cracked so in the interest of time I let him use the engine I had ready. And as it goes this engine worked very well. The 2800 pound Duster ran 5.72's. Almost matching the best time of the B1 engine that it replaced. Lived through one ring and pinion, my fathers great idea to try 5:13 gears, and a transmission failure. Over 200 passes. Well the other night at Red River (now Thunder Road) during a time trial water on the track caused the engine to over rev its last time. The pics are of one of the used rods.

That blows. Hi high did it go?
Looks like it was very well pre cracked, What else did it hurt? Not sure but he has a 7500 pill in the rev limiter.

I also still had a nice set of pre tested (used)JE dome pistons. Just curious, how did the piston pin look on the failed cylinder? Slide out of the piston OK?

Well I started on our replacement B1 low deck. I ordered some new Scat HBeam rods to complete the rotating assembly and one of the rods is defective out of the box. .003 over sized on the big end. As in 2.503. Im shocked, and awaiting word from Scat on what to do.

If they are numbered close id send the whole box back and ask for a new full set, who knows if the same person/shift/batch are ok.
Its your money, you should expect decent parts. Another example of why its best to check things asap after receipt. Im sure they will be cool about it and replace them. But now I have to answer to the old man

I'm glad you mentioned the rust. I was intending on sharing something that I found out the hard way about blocks that have been crack repaired. DON'T USE THEM As I stated in my first post this engine was built using parts that really had no value. Perfect place for me to test a repaired block.
