What was that engine in? Was it installed from the factory? I never heard of an aluminum factory small block.

Guys it is a BOWTIE block---I dunno whether GM ever assembly line installed any Bowtie blocks but I'll bet that they were all aftermarket stuff AND NEVER came in a production vehicle!!! No point running out to your local salvage yard hoping to find one cuz they were/are probably OVER the counter blocks----Comp

How many have to be built before its alowed in SS?

It says here 2 were built. All aluminum 350 250hp. And I remember reading somewhere that this engine has 11:1 compression too! Probably a bowtie block...and im assuming of the 50 somthing built only 2 or more got this engine.
