mine don't have #'s on the back. the only #'s i see are in between the lobes i will read you the #' starting at the nose. i.5 - cwc - (d3 c3)-2-5-5-1-0-0-8-1-24 i am sure this is the correct cam as i am the second owner of the car but you never know..hth.......Bob

Mine has an engraved ITXBEF on the back. Yours have this Bob?

Julio mine has nothing on the back, just a machined surface........Bob

 

[Sleeper-6]

Let's see here, Mine has "1308" and "I5" cast between the first journal and lobe, "CWC" between the #1 intake and exhaust lobe,"D2" and "C2" between the #2 intake and exhaust valves, "E8" and "09" between the last lobe and rear most journal, and "961240" on the rear surface.

I believe this is the stock cam, I was in the car when I got it, but someone had been into the engine once before.

you might have the twin turbo GN cam Bob

 

[Sleeper-6]

I thought that was from those double to secret FBI cars the EVERYONEs cousin/uncle/friend/brother had.

 

[Razor]

Nah.. its from a twin turbo Pursuit GN..

So the stock cam doesnt have any inscriptions on the bottom?

How could you tell the difference between an NA cam and a turbo cam?

 

[Super6]

Julio i have a na 109 block in the shop. i think the cam is still in it...i see if i can check it out................Bob

 

[Razor]

That wont have a turbo cam in it. Wonder if there is a difference? But do look at the back of the cam..

na 109

came from a 86 buick regal #'s are almost the same#' starting at the nose. i.5 - cwc - (d1 c1)*-2-5-5-1-0-0-8-1-(24-a)* ............Bob

 

[Super6]

Did anyone ever figure out what cam Julio is talking about?
Marked "ITXBEF"
I just pulled one out of a car and am wondering what it is.

Razor, I have a couple of stock cams sitting on the shelf, when I get home tonight I will check and see what #s are on there, also I pulled a few N/A 109s apart recently and have the cams sitting in a box, I'll also check them #s, Jr.

Julio,
I broke out my old KB catalog for craps and giggles and here is the specs in case you would like them for that cam.

KB Mark 1TXB
Lift .460 on both ex and int
Dur .260 both exh and int
114 lobe sep
1.5 to 5.5k power band

And of course I have to post the gain....KB says 20 HP and 2mph and .2 tenths...LOL
