I'm not really sure what I'm lookin at but no, its a 454BB (typo) on either a 79 chevy or GMC. Excuse my mechanical illiteracy. All I know is that it says

"1971 8-307 2bbl 215HP@4800RPM and 305ft.lbs.@2800RPM 3.875x3.250 bore&stroke and 9.0:1 compression

VS

1979 8-454 4bbl 205HP@3600RPM and 350ft.lbs.@2500RPM 4.250x4.000 Bore&stroke 8.0:1 compression"

I would appreciate some further explanation. Is the 454 still faster since it's @1000 less RPM? and am I right to say that our torque are only 45ft.lbs. from being the same??
