Using Tim Banning of FHO is never a bad thing, but he himself will say there are other good builders of the hemi motors. I do not think you want to ship all your stuff so far away but if you did you would get a great hemi back from FHO. If I read you correctly you are using a blower on your motor. Tim at one time ran a 500 CI Hemi with a 14-71 with carbs on top and that was an awesome ride he had. I think everyone within 500 miles of tim uses FHO to build their motors. I have used FHO since about 1982 for something on every hemi I have had accept my learning experience with the Funny Car Alky guy that screwed me over. This other guy Dan seems like a good choice also. Take a drive over to his shop and drop the hemi stuff off and have him come back after the build to your house when you want to fire the engine up in your car. I would believe that Dan might want to run the motor on the dyno before he gives it back to you. That is what Tim at FHO does.
