Default How much boost can a L33 take?

Hey guys I am currently bouncing around the idea of a lightweight build to haul some *** in. Anyways I was thinking along the lines of an AMC powered by a built and boosted L33. So the main question is, are these blocks any good for boost? Has anyone found the breaking point? Are these blocks basically a smaller bore LS1?

I've ran 20lbs down mine quite a few times now while dialing in the boost controller between my rx7(tc78) and my ltd(precision 76). On 18lbs in the rx7 I ran the times in my sig and 17.5lbs on the ltd I ran the times in my sig.

Wow, I had seen your post earlier but just thought it was an iron block 5.3. Thats pretty damn impressive with that ltd. How much did your rx7 weigh? Also, have any dyno numbers?
