i bought a cam today i was told it was from a 92 or 93 LT1 but im not sure that is what it is. the reason i dont think it is an LT1 cam is it has a fuel pump lobe and as far as i know LT1 cams did not have a fuel pump lobe. the cam has 240 stamped on the back of it. i have no idea what it is or what its from. PLEASE HELP ME!

 

some aftermarket cams have the fuel pump lobe,jimmy

 

i had an LT1 short block sitting in my garage than is trashed i pulled the cam out of it and it has the fuel pump lobe on it. but its a stock lt1 cam from a police car. i dont know why i did not think of it earlier but i compared them and they look to have the same lift (judging it by eye) but the duration it alot different the mystery cam has much shorter duration than the other lt1 cam i have so i dont know what it is.

 

look just below the fuel pump lobe closely, thats where TPI cams are marked
