This is the Chevy LSx motor that normally has EFI and 8 coils with computer controlled ignition. To comply with rules they have to run a distributor and carb, so they have created an adaptation off the front of the motor. I was in Bill McAnally Racing Nascar shop last month and they had a bunch of of them in there. They are great motors, 6 bolt mains, great flowing heads, all aluminum.
