How were early 70’s V8’s so large yet relatively lacking in power

940 viewsEngineeringOther

How is it possible with the Chevy’s and Caddy’s with their pure American 6 litre V8’s didn’t get past 300 horsepower.

It seems so implausible that such a massive engine was so inefficient.

You can get big power out of most of those large displacement malaise era engines, they were just “choked” due to the laws during the fuel crisis. Most of them simply need to be fed more fuel and allowed to breathe in more air and their power can be increased significantly. Changing out their cams to change when ignition happens with how much fuel at what compression also makes a big difference but sadly most of them were also built with cast heads and rods to be cheaper because they were never intended to be subjected to the kind of power their pure displacement is technically capable of producing and unless they’re upgraded to forged, they’re likely to break under high RPMs and a broken rod can be shot right through the block.
