There are not a lot of people making 4 digits with stock LA Mopar blocks and furthermore I know Brett quite well as he has done 3 engines for me and is working on 2 more and I know the owner of the W5 engine and it is not a stock block AND Brett does NOT love the W5's for the same reason I been talking about but you choose to ignore in-between pounding your chest.....he doesn't really want the liability or bad taste in his mouth by going out of his way to use W5's that have a history of drinking water.....his meat and potatoes is W8 and W9 and that should be anyone with a fully functioning brains heads of choice ALONG with a race block if they are looking for 4 digits.......
