I think if you really want mopar stuff you can get it. In the last few years I have come up with several motors with aftermarket RB blocks. I bet you could go on RJ and purchase 2 or 3 motors (hemi or RB) with aftermarket blocks. We all know some mopar guys beat to a different drummer and people don't want to deal with them. Sometime I understand Indys no customer service. I tried to order B1 TTI headers from them and they would not sell them to me. You don't want my money, no problem. No big deal I went straight to TTI. I did not even tell Russ I have 2 other Indy -1 motors. I don't even race seriously but a few times a year. I would think a hard core race guy would mingle with other mopar guys that would be getting rid of parts. Who know maybe I just that lucky and need to play the Lotto.
