Browsing through the yards today and we found a TBI motor in a first style second gen 75-81. Anyways aluminum intake that is part of the head like a 390 Furd motor. TBI pod says Rochester tbi on it. Lastly the rockers were staggered like a big block /forums/images/graemlins/confused.gif It appears to be a sbc. Dist in the rear oil filter in the same place, firing order the same IIRC but like no block I've ever seen /forums/images/graemlins/dunno.gif 1619906 was stamper on the intake /forums/images/graemlins/dunno.gif /forums/images/graemlins/thinking.gif any ideas?
