Yes, fairly low hp due to a very small cam, restrictive intake, and restrictive exhaust. But the torque is pretty good at extremely low rpms which makes it seem more powerful than it is.
Nothing a mild cam, intake, carb, and a set of header won't fix. On an otherwise stock low compression 454 engine, 325hp+ and 450 ftlbs+ can be obtained with a few bolts-ons.
I have seen dyno results showing 345hp and 490 ftlbs from a 7.5:1 cr 454 with a tiny 202/210 flat hydro cam, headers, rpm intake, and 750 holley.
