Looking for an UN-CRACKED aluminum stock bore block.
Well, during assembly, I discovered that the block I bought had a crack in the ear where the starter bolts up to right along the block on both sides of the ear. Needless to say, at this point, my machinist and I both agree it's better to just get a new block. So I'm looking for an aluminum stock ls1 bore (3.898") block. I don't care if it smokes, has rod knock, just no cracks.
I'm willing to drive upwards of 200+ miles to come pick it up as well. I'm about 30 minutes north of Philly, so anyone in New York, New Jersey, Maryland, Delaware etc etc is fair game. Sponsors, if you have people doing new motor builds, let them know I'm interested in their block.
Thanks guys.

Yeah it sucks, but I might be in luck.... well, more luck that I currenlty have been having recently..
Here's the crack I found...
I'm a little upset at my machinist for not catching it prior to prepping the block, but to his point, he wasn't checking every inch of the block for imperfections or cracks. He was just checking the critical surfaces he was machining.
Oh well, **** happens, you learn, you grow, you move on.

Only issue Fran is it's cracked on both sides and you can see the crack in the bolt hole for the bell housing. My machinist is concerned with how much the block might distort from welding it that close to the cylinder liners.
The block is ready to go for 3.905 pistons. Been line honed, decked just enough to clean it up, it was literally ready for final assembly.
Want the block in exchange Fran???

What does anyone else think, can it be welded? My machinist sounds like he doesn't want to do it, he's concerned about distortion from the heat, and then having to clean up the bores if they rust from sticking the block in the oven, I just don't know.

I got a guy that runs his own fab shop and even runs mobil so if you didnt want to go to him he'll come to you. pm me if interested, he said its a cake weld job for anyone that has a clue of how to weld.

Fact is, he's an engineer turned machinist (15+ years experience) so his first concern was the impact to the tolerances that welding the block would have. He's worried about distortion ect in the block. Granted, he's not a full time welder, but he's fixed heads and such. This might be why he's leary to weld it himself.
Please feel free to PM me any info. These welders, are they familiar with welding on cast aluminum blocks?
Thanks guys.
