the 904 you have wont bolt up and isnt strong enough anyway----however there are built 904 running behind built 426 hemi drag cars running 1000hp up----the V10 shares a bellhousing with the cummins motor---best bet would be to find a 2 wheel drive 1994 v10 one----and there is a guy on this site that builds custom looms for the efi motors---think he might even be able to flash the computers---bob
