Well the time is near. I was driving my truck and out of nowhere, I started to here a light knock. I pulled into a gas station and popped the hood and gave a listen. When idling and at a 2000-3000rpm rev in park there is no knock. However when it's under a load and I get up around 2300 she start to knock. I got it home and yanedk the valve covers off to see if maybe a rocker arm was loose. "WISHFUL THINKING" and everything was just fine. However, I drained the oil and there was a good amount of metal shaving in the oil. WAH WAH WAAAAH. :o Looks like i have some work ahead of me. At least i got a good amount of driving out of it this summer. Man I hate SBO engines. Maybe now it the time to do it right and drop in a BBC baby!!!

Sorry to hear that.

Yeah, it seems like it's when you're not lookin for trouble is the best time for it to find you!
-

Yepper it a SBO. The truck was my Uncle's then passed to my dad then me. My uncle did the swap years ago. The truck was a 5.7 diesel. Apparantly they used the BOP tranny or "uni-bell" tranny housing on them or SOMETHING LIKE THAT. So rather than doing a motor and trans swap he just threw in a SBO. The install is really nice. Looks as close to factory I think. People are always thrown off by it. They look like a dog that just heard a really high pitched noise ;D However being and Olds motor I knew it would not last long with the way I like to drive. Guess I should keep the high reving tp my F-body 8)I love to let the LT headers and Super 44's muffler make some noise. I just dont really know what to do now......my buddy has a nice 383 SBO he is selling out of his wife's Impala (he's going back to the original 327). However i think he is asking to much. I've tossed around the idea of a LSX/4l60e swap as well. If I come buy a wrecked out F-body or Truck i may go that route too....... or a nice crate motor?.......who knows, I have a long Wisconsin fall and winter to figure it out. Wish me luck.

Well I got the motor yanked last night and got it on the engine stand ready to tear it down. Wish me luck ???

Good for you. Personally, i would keep it oldsmoboggie powered. That's what i would do.
2) Please keep a detailed diary of your engine rebuild.

Punch it .068" over and fit it with olds 425 pistons. ;) You'll increase your compression ratio from 7.55:1 to about 10:1
