Just curious we run a 1971 402 big block Chevrolet in our stocker and was wondering if I can get an opinion from knowlegeable engine guys. How much horsepower do you think is a reasonable number for our engine?
The achilles heel of our engine is the flat intake manifold that looks like the fuel has to run uphill at one point. We have the 820 casting cylinder head. Thanks
