What was the final diagnosis of Cooper's IAII aluminum block that grenaded a year ago? There are pages and pages on the KRE blocks destruction, but I never read the cause of that particular IAII to come apart. TIA

Only failure I'm aware of from Cooper in 2006 was at Norwalk, when he broke the front of the crank snout off the crankshaft. That's not the fault of the block, that's from overdriving a large roots blower. Hemi and BBC crank snouts are bigger than a Pontiac's and can handle it better.

Larry Cooper, NA bird, hear the mains fell out of the block but you know how rumors go.

OK, wrong Cooper (LOL). Actually, that failure was discussed on the board. The consensus was it being a result of standing it on the rear bumper too many times and starving the mains without pulling it apart for inspection. Tom Vaught weighed in on that one as well, do a search and you'll find it.
