here is the small block chevy race kit(F2) that i bought brand new for 4500.00 and adapted myself. all mounts adapters are 1.5+ 6061 Like Josh said though a big problem with mopars is the lack of surface area to mount to since you are mounting off the water pump and not the cylinder head like chevy and fords. that problem can easily be overcome as long as you don't want to run a mechanical water pump
