Funny sideline about the GM LS series...
Turns out it seems that GM ripped off Ford's FE series motor design. A SBF distributor drops right in when an LS is setup without electronic ignition. The head bolt pattern is a mirror image of Ford's, so much that an aftermarket GM block manufacturer made his block so that either Ford or GM heads would bolt up, and you can even run GM on one side and Ford on the other to line the ports up. The deck height is the same as an FE at 9.2 inches.
I know it's not Porsche, but still interesting if you're into cars.
