We have built a few now. Only things we have noticed that seem to be common place is the lifter bores are slightly over sized and the lifter bores have less than a desirable finish from the manufacturer. Nothing we weren't able to correct though. Another issue we have ran into is the deck height being slightly low. Other than this we haven't had any other issues or complaints. Concept Performance has been very helpful with any questions, or concerns we have had.

Have you guys measured the cylinder length on any of them?

Thanks for the info Aaron. I was planning on using an ls3 block with dart m.i.d. sleeves but saw this block while searching for some parts , so I'm trying to workout which option would the most cost effective. Yeah I know iron blocks are the cheapest way but I don't want the extra lbs that brings with it.

Also need to figure out which option will be the strongest of the 2. Any thoughts or opinions on this.
