well i have the old 4.8L on the floor in the garage - i thought was to build a 382 out it, but i am pretty sure my 4" crank from the 6L is distroyed at the #3-#4 rod journal - so right now i have no idea what i am going to do really. I want to build something that will work well with the vic jr and a 650 0r 750 carb setup. I might just toss the 4.8L back in so i can cruise for the summer and work on something this winter....

 

i pick the short block up with a set of 317 heads from a guy off of ls1 (very legit) and once i got it home i tore it down and put new bearings/rings in its cuz no one knew how many miles were on it. So Im thinking that the bearings could/should have been 0.010 undersized cuz I had a slight bit of snuggness on #5 and #6 rod journals - but #3 and #4 broke! I am also thinking that the bearings on #3 and #4 spun b/c the one bearing that i did find was wore right down to the bass thats in the bearings....whatever it was forsure i might never know-just know that it totally tore everything up. I think that I might go out and tear it down the rest of the way tonight - motor is still in the truck now so I havent seen the insides totally yet...

 

Was it fun?

 

The bearings are supposed to spin.

Totally sucks. Good luck on the next one.

 

Thanks guys!!! If anyone knows or has of a 4" crank that is in good shape let me know - I dont think I want to venture into buying a new one at 2k!!
