Yep, you all are right. I was talking about the PF motor which is Digifant but exactly the same as the RD motor (10:1 compression, knock sensor system but with digifant and more hp). When I go to the wreckers I see a bunch of 8vs with knock sensors and digifant so the PF must be what they are. Sorry if I said anything derogatory concerning this (I try not to). Dave
