Unless something is done about the siamesed ports and terrible intake design it's wasted money. As a low rpm torque engine a Stovebolt excelled but no matter how heavy you smear lipstick on a pig it's still a pig in the performance theater. On an overHEAD valve engine the HEAD is everything and all the short block has to do is stay together. If one has to use an I6 then consider the Atlas to keep it all Chevy or a 300 Ford for all American. Lots of foreign I6's to choose from but if serious performance is the goal then seven main bearings and a 12 port head is the base foundation.
