Looking for Ecotec info. Building a drag race only car. Either tube front end car or altered/street roadster. Ignorant at this point, which model/year cars had the forged steel cranks (8 bolt?).... Just the turbo/supercharged engines, or others???..Anything I should avoid?.. Will want to be able to input air ratio/fuel changes to the computer,etc. Have had 2 turbo cars so far... just not familiar with the Ecotec. Mike
