"All the headbolt holes have been helicoiled with 1.125" long helicoils, which are also coated with thread locking compound. There is one head bolt hole that needs to be repaired, as the Time-sert that was in it broke. There is enough material there to use a Big-sert to repair it. I have photos available upon request."

The bores have scratches in them that are visible from the photos, then in the description he says that a headbolt hole is broke. Sorry he wore the block out and I wouldn't put a rotating assembly that I cared about into that block.

According the rules for outlaw it has to have an LT1 block, I doubt they are are going to call it that.

I wonder if the cylinders have sleeves, no way that aluminum cylinders would last

This is the block originally owned by the guy with the impala SS with the Donavan 343 LT1. He purchased 2 and ended up selling this one.

From what I know of this blocks history. Guy purchased it. Put it in his drag car then raced with it couple seasons. Engine took some damage. So he sold it and it was repaired. Used in another nitrous feed drag setup. Till it took this damage

Both times it made amazing power. But you would need to send it to Donavan and have it resleaved(which isn't cheap)

By the time it is back in working order. You would be out the price of a new modified Block almost.

Just curious anyone have a Link/info on the guys car?

The block is currently in my possession. The bores do not have scratches in them. The scratches you see are from the sleeves being pulled out to inspect the block. One of the Time-Serts that were installed broke due to improper installation, so we pulled everything back apart and checked the block. Whoever had the block before me installed 0.500" long helicoils in holes that averaged ~1.3" deep. We didn't torque any of the other head bolts, so I went and replaced them with 1.125" long helicoils that I got from the original owner (Jeff Green) which is the same way his block is set up, and has been set up for years. That is the only damage that I have seen thus far on this block. I haven't noticed anything out of the ordinary other than the sleeves needing a hone to get rid them back concentric. If there is anything that I don't know about it, please feel free to contact me via PM.

Thanks for clearing that up. One question though, in the ad it says that it was originally set up for a double roller so the mechanical wp and opti can't be used. I understand that it won't drive the mechanical wp without a stock type timing set but why not an opti?

No problem. I just didn't want anyone to think I was out trying to sell junk, as that is far from what I'm trying to do. The build has just changed directions, and I figured someon would have the oppourtunity to build a bad a** N/A motor. I will tell you one thing, they didn't think before milling the deck to get rid of the ring for the custom copper gaskets, so the deck height is slightly shorter than it was.

I don't see any reason as to why it won't drive an opti honestly. I think it's all in the timing set that's chosen. I'll have to give Jeff a ring about that as I'm curious now.
