Hello,
Could someone please tell me what was the factory horse power rating and torque for a 70 402 c10 chevy truck. I only have books for 72. Thanks, Dan |

Re: 70 Big Block HP
I got the 300/400 gross rating from a muscle car book I have. That's the passenger car 8.5:1 four barrel 402. The c10 350 was for sure rated 255 gross
