it put down very modest numbers with a carb that wasnt set up properly. i had the accel efi installed and then changed the entire build due to a local shop in tucson absolutely destroying the body of the car. it never saw dyno time with the efi. it should see significant gains.
heres the dyno chart from when i purchased the car with the bbc/700r4 installed
