Re: 1970 L47 400 BB Torque and HP chart
Are you looking for numbers for a big block 400 chevy? Ur gonna look till ur eyes bleed cause Chevy didn't make a BB400. They made a 396 and 402, which are the same motor, just a 402 is a .030 over 396. I wanna say it had to do with a car having a bigger motor than in a truck.
