Iron Block LS1 is here! To all the nonbelievers...see Summit Jan.-Feb 2012 Catalog PG. 315 or goto website and enter part# 150105 !
You can get a 4.030" bore iron block LS1 for $749.95 and delivered to your door via truck for another $149 ! I am guessing since they are "seasoned", they were once 5.3L truck engines.
Look at what all comes with it.
"The LS engine design has incredible potential, but once you start bolting on big superchargers, an aluminum block just can't contain all that power. These Summit iron LS blocks have all the same potential, but the cast iron construction is capable of withstanding high horsepower applications. These seasoned blocks feature a finished 4.030 in. bore and a 9.240 in. high deck. They feature 6-bolt main caps and a 1-piece rear main seal, and include cam bearings and freeze plugs."

Sounds good, but almost every part/block I've seen come through my shop from summit ends up having to go back to a machine shop cause it was so poorly done. Tolerances waayyyy out... U vould take the chance, but you get what you pay for kinda thing. I'd hope otherwise and if someone proves me wrong i be more than happy to swallow what I said.

I didnt know the year just a guess. It has a 4.06 bore if that helps. I know the junkyard guy well he called ne saied have a newer vetter that was hit by a semi in the rear and some one had it before them and took off the heads and intake. Ao if i get heads and intake im ready to roll. Bore looks good had low miles. Are they forged blocks?

We have a race engine machine shop in house and I know the that any "finished" block such as this that a customer brings in from an assembly line type of machine shop usually just doesnt cut it for us. The best way is to have each cylinder honed specifically to fit the pistons. Im not saying this block is ****, but its nothing magical at all.
