lt1 cam i.d. help please * with pics *

i got a used lt1 cam from a guy. didnt tell me what year. and from finding your super info thread/sticky i have found there is 3-4 diffrent cams.

well mine has a tinny fuel pump lobe on it but its all round no lump to run the pump rod. and on the cam just past that is ( gmpt bc 13 600 ) thats the only info on the cam i can find.

and help would be super thanks.

EDIT MORE INFO : checked the cam with caliper. found 1.5550 tall lobe then 1.2695 wide lobe for a diffrence of 286. this is super close specs not 100% perfect. then other lobe was 1.5575 tall and 1.2715 wide for 2.86 diffrence.

mabye this will help id the cam. i did look at the link in the swap post and 96 had close specs from lobe to lobe like this one minus the at .050 lift conversion.

i have posted a pic of the cam .

Re: lt1 cam i.d. help please

That number you listed is just a casting#. Unfortunately, it doesn't help to figure out what cam it is. The only way to tell is to find out the vehicle info.

This is the best info that I could find for stock LT1 cams:

93-95 LT1 202/207 @ 0.050" .450"/.460" Lift, LSA 116
96 LT1 200/207 @ 0.050" .447"/.459" LSA 117
----------
Hope this helps!
