705-gmpt-bc-16 now i know that the lt1 cam pics i have seen do not have a fuel pump lobe. mine has a completey round lobe on it. here is a pic.

GM stopped putting a fuel pump lobe on passenger car engine cams around 1990. They were all fuel injected by then anyway, Anything aftermarket or factory performance crate engine cams will still have the lobe.

i understand the lobe is suppose to be gome. the one in the picture is completey round so it cannot run a fuel pump.

So.... what's the question?

all lt1 cams i have seen do not have even a round lobe on them where the fuel pump lobe is suppose to be. but even at that here is the reason it is trash. they said they removed the cam from an engine like this. i dont think so.

I have two LT1 cams. A 95 F body cam, and one from a B body. They both have the round lobe area like yours.
