Did this ever get off the ground?
There is zero competition here. Maybe .00000001 % of the people in the world with a rear wheel drive GM are going to have a motor like this built. How many LSx Impalas have we seen. And how many of them are 427+ strokers? To be honest it has been a half a year since this 500ci motor has been available, and just recently we got the first request for a quote for a 500LS motor. It did not come form this forum but from a lineage of other work non LT1 Bbody related; Westech >> JBA >> Pontiac Enthusiast Magazine >> ='s GTO owner wants a quote for a magazine car to make I can't say with what.Only note about this post though is that is has all the looks of an advertisement and is posted in a forum that is sponsored and paid for by another sponsor who also builds engines.
