can someone tell me if there is any way to identify an lt1 cam? my reason for asking is because I bought an "lt1" cam off ebay and after after buying it I realized that the guy I bought it from could have taken any cam and said it ws an lt1 cam. so I just want to make sure that it is an lt1 cam before I put it in my car

You'll need

1) An engine block
2) A crankshaft
3) A timing set
4) A degree wheel
5) A dial indicator w/ a magnetic base
6) A solid roller lifter (which can be made from a hyd roller)
7) A piece of thick wire to use as a pointer (a piece of a coat hanger works from me)
8) A connecting rod with a piston attached to use with a piston stop
9) A crank snout tool to turn the crank with
10) A long rachet or breaker bar
11) A pad of paper
12) A calculator
13) A set of instructions on how to read a cam using the tools I listed
14) At least an hour of your time
15) A bottle of Excedrine after you're done

You can find the instructions at www.CraneCams.com , www.CompCams.com , or at www.ChevyHiPerformance.com (and "yes", I spelled it right).

What are the numbers on the rear of the cam? Also, the Lt1 cam has the stepped nose, like the sbc factory roller cams. Also, the cam sprocket snout thing (its name is slipping me) is longer.

And then you'll probably want to know which one of the 5-6 factory LT1 cams you might have. Guessing that this is not an early '70s LT1 solid lifter cam, all the later LT1 cams have no fuel pump lobe.

Here is a pic that should help that I whipped up. This is a stock LT4 cam. Any LT1 cam will resemble the same characterisitcs.

Didnt the non-vented opti equipped LT1's have a smaller dowel pin?

Yes. But it is still a bit longer than a stock Gen 1 hydraualic roller cam.

well the lt1 cam i got off ebay was said to be from a 95 trans am, and it dosent have that dowel thing on the end, not sure about the fuel pump lode, will have to check

It doesnt have the dowel pin at all as in its missing? Or its just shorter, like normal SBC short?

What does it say on the rear of the cam? Or anywhere on the cam for that matter?

It should have the same length dowel pin as the shown in the pic of that LT4 cam I used to have. If not, that cam has been tampered with or is not an LT1 cam.

Like shifty said its possible its a lt1 cam and they grinded the dowel pin down to make it fit in a Gen I block.
