Are you insinuating that the D-max boys are not using Hard block. If you are making real power and want it to live filler up and bring it on a trailer.
As far as I know, few if any real Duramax Pickups (you use it to tow trailers and haul things, and it has a real pickup bed) grout their blocks. Some racers do, but most don't. A Dmax block ain't as weak a Dodge block is AFAIK.
I have a question: Why do they make those max effort Dodges look like pickups? Isn't that just a waste of money?
I think they look better without the glass panels on them.
Another question: Do they still have to spray the ether from the can, or do they just have a tank of ether on board? Is ether really a diesel fuel? I just haven't seen it at the pumps before, just regular, plus, premium, and #2. Is it a Eastern thing or something?
