Yes, they are dogs. All the auto makers in the mid 70'* dumped compression ratios down to the 8'* with big chambers and dished pistons, put in economy cams, then saddled the cars with poor emissions controls that truly sucked the life outta the motor'* potential. The HP wars didn't come back until the late 80'*. I don't know what is available for this motor in terms of better heads, induction, and cams. It'* probably pricey if it is available at all.
If I were the owner of such a car, and liked it well enough to want to drive it a lot, I would budget a replacement motor into the equation...or live with the dog until something broke and I needed to do something about it. It'* legal, even in California, to upgrade the entire driveline to a newer model. So think what an early 80'* Bonnie would run like with a late 80'* TPI 350 in it...or a mid 90'* LT1...heck, even a TBI 350 from a late 80'* C/K pickup would about double the HP output and be cheaper than overhauling the existing motor.
