Hey guys, I have an unknown LT1 camshaft I'm trying to sell and I need the specs. I searched the Comp Catalog and came up with bupkiss. Can anyone help? Cam has the following written on it.

LT1 33165/33175
HR112+4
X2022

Any help is appreciated.

Thanks,
Anthony

 

Might want to just call comp, they would know better then anybody else.

 

I had subscribed to a thread where Bret had an answer for me in like 2 seconds, but when I went to my subscriptions the other day it wasn't there anymore. Not sure what happened to it, I tried searching and didn't come up with anything. If I don't here anything back I will probably give them a shout after work or something in the next couple of days.

 

Anthony,
I'm going to take a stab at this......33165/33175 are lobe numbers. Take the 5 off the end and you have 3316/3317:

3316: 288 adv dur/236 dur @ .050/.521 lift with 1.5 ratio rocker
3317: 294 adv dur/242 dur @ .050/.540 lift with 1.5 ratio rocker
112 degree lobe separation w/4 degree advance ground in.

HTH.

 

That should be right, but if you want to be 100% certain you could call up comp and have them send you a cam card if you give them a serial #.
