I'm rebuilding the motor in my 1985 camaro. I don't think it's original at all. But I need help identifying the camshaft. The numbers on the end are a mess and going every which way. But here are the number
top of cam
Br280-2h with 1424 under it

left side 201037 with 1159 next I to it at a angles and slightly larger stamping

Right side 119306 the 9 was doubles stamped so I'm not 100% sure it's a 9

Bottom of cam.
11-31-00

Any info would be great. Also all of the numbers aree on the distributor side of the cam.

119306 is an old crane cam's cam core #. It could be a crane or a crane/wolverine blue racer cam

My guess is it's a blue racer.

br (blue racer)
280-2H grind number
1159 part number
119306 cam core number

11-31-00 should be the engine suffix code (11), and 00 would be date code for 2000

If my thinking is right then that would be a cam that specs as
280/290* adv duration,
214/224* @.050"
.443”/.465” lift
112 LSA

Night rider where did u find that information?

My brain and Looking in 15 year old parts catalogs and online. lol.

I knew the 119306 number as soon as I saw it. Crane cams was the major cam that I used for many years in my customers engines, so I have seen that cam core many times. Crane used that same core for 20 years or so on millions of cams.

So it was a crane core, I grabbed my old crane and blue racer catalogs and matched up some more of the numbers.

I couldn't find the 1159# in my books, so I googled it and read through a bunch of post. I can't remember the site I seen it on (might have been a chevelle board) but a member I knew from another board (pdg67) had posted a lot of the WBR (wolverine blue racer) numbers and the 1159 came up there.

OK thank u again. I wanting to go bigger what's should I run?

What engine size, compression and what heads? The cam needs to match those closely for best power.

You said '85 camaro, so I'm guessing 305?

That old WBR cam is an old, old profile, very lazy ramps. Look at how high the adv. duration is and how low the .050" lift duration is.

Staying with the same .050" duration and using a modern lope profile cam will gain you 15 HP or better.

The smaller the engine, the less cam you need. The cam acts larger in smaller engines.

Ya 305. Stock motor.

The L98 heads do not flow very well past .500" lift. So no real reason in looking at big lift number cams. It will just be valvetrain stress with no real gain.

.490" to .515" max lift range

But duration and LSA matters more than lift anyway.

The duration must match your compression and engine size.. What engine do you have?

Here you say 305, in another post asking this same question you say 350?

I know you want the wild race car sounding car, but it's gonna kill off what power you do have.

With your 9.5:1 305 the biggest I would run would be something like a 218/224 @.050" with a 110 or 112 LSA.

These cams would work good.

You can go bigger but you will kill power. The 305's tiny bores can't move air at high RPM so why use a big cam to shift the power up to a higher RPM range that your engine can't breath at.

If it is a 350 with 9.5 to 10.0 compression then you can go about 5-6 degrees bigger and be ok

Night rider. Of what u say is true.for a 305. I guess I'll be reinstalling the cam I removed

Now if anyone reading this could help me with my exhaust post

Well now the cam you pulled out is the same .050" duration but it's an old profile with much slower ramps.

A swap to a modern profile cam with the same .050" duration would gain you 10-20 HP over the old cam you have.

A good way to tell a fast ramp cam vs a slow ramp one is the adv. vs. .050" duration.

Your old cam is
280/290* adv duration,
214/224* @.050"
.443”/.465” lift


Faster ramp speed cams will have like 264/270 adv. duration and a .050" duration of about the same 214/221

Any help with my exhaust question I made a post about it but haven't got any help

I'll check out your exhaust post in a bit.

I just noticed all my links to cams are dead.
Here's the part numbers to some cams that would work great

12-238-2
12-208-2
112571-12
12-365-4
12-552-4
12-239-3
10120702
12-209-2
12-556-4

Look those up on summit's site. Any one of those would be a good pick and about the largest you want to run in a mild 305

Frankenvette

ANY IDEA.

Night Rider I need some help identifying a cam?
