630-cpc-bc-7. It has the octagonal flats and a factory number but nothing comes up for it.

So the base lobes of this cam measures 1.32 and the intake is 1.56 and exhaust is 1.58, so .360 and .390 lift

This is a factory roller with a fuel pump lobe. Any ideas?

Sounds like a 305 peanut roller to me. .350/.385 lift.

Did any of them have a fuel pump lobe? That is what has me baffled

My '643 cam from a 1987 TPI had a fuel pump lobe from factory.

That would make sense. Same cam used in the 1987 LG4 w/4bbl carb and mechanical fuel pump.

Yep the 87 and 88 LG4s used the same cam. The big cars did not go TBI on the 305 until 89 IIRC.

the b-bodies had tbi on v8s since '89 but on v6s since '87. I believe same with 87/88 g-bodies.
