Some of you will remember my original thread on the subject. Refresher course here:

Anyway, I bought a used 327 hoping it was a solid lifter set-up. I pulled the cam tonight to find out exactly what is was and here is what I found. Grind# E921P. It is manufactured by Elgin and the specs are as follows:

Hydraulic .450/.460 Lift - 224°/224° @ .050
.050 Duration-.224/.224
Valve Lift-450/460
Lobe Center-114

Street machine & high performance street use. Biggest cam w/stock converter. Use lower gears. Mild rough idle.

I did a search on Elgin because I've never heard of them. Their web site (http://www.elgincams.com/index.html) pretty much says they are a specialty camshaft manufacturer.
Has anyone ever heard of these guys and what type of performance can be expected if I use it?

More bad news is that the cam bearings look horrific. Looks like someone took a wood chisel to them. The bearing surfaces are absolutely the worst I've ever seen.

 

We handle Elgin engine and chassis parts. Very good company that actually makes parts unlike most of the others that are just renamers or repackagers that lure one into buying there parts by high priced and profiled advertisements. One of the oldest piston manufacturers in the country. Several Indy race cars in their history and they have some excellant camshafts.

 

those guys been around awhile, and make good stuff. I would be wary about using that cam,,,with the journals like you describe. I would think from what I know, it aint the manifactores that did that.

 

I agree with the others - Elgin has a good reputation. Sounds like you are going to need a new cam and bearings, though.

 

That's L-82 cam.

 

That is almost the same specs as the no or low performance cam that cam in my 79 L-82. Unless 225 hp is something to brag about.

 

yeah, very close to L82, only diff is L82 has 222 duration on both.

 

I remember way way back Elgin made outboard motors for boats. Don't know if it was the same company

 

actually with the right heads (2.02 for example) and a decent carb / intake combo that a nice street cam a littel morelift that the stock 70 z28 cam with a little higher LSA

.447/.447, 224/224, 112LSA

 

They made watches too !!!

 

L-46 350/350 cam. Also used in the L-82. Not much glamour but it will get you around.

This is a copy of a previous post:
(quote) The particular unit you are working with here, the 350"/300HP SB is one we've done some extensive testing on, while maintaining pump-gas compatibility along with being 100% stock appearing. This means factory intake, carb, and exhaust manifolds. This particular unit was done for a '69 Camaro. Upon finishing it up and delivering the car, the customer called and said felt more powerful than his solid lifter LT-1 powered '68 Camaro.

We've been able to produce 350+ HP and 385+ Ft.Lbs. Torque using a 9.75:1 final C.R. This was also staying with the stock L-82 factory (3896692) hydraulic cam, 224/224 x .450"/.460" x 114LS. The cam was "picked" by the customer.
We did have some light-weight pistons inside from Ross. Aside from some simple "bowl" work on the heads, there was no other internal "hidden" tricks used. Thanks, Gary in N.Y.

P.S. We are convinced that a step up on the cam would have put us somewhat past those existing numbers. Not sure how much, but would have guessed about a 25/30 HP gain. (end quote)

That L-82 cam is an excellent all-around piece. G.M. was well aware of this when they ground it up. It works well with powerbrakes and maintains higher manifold vacuum levels for some add'l gas mileage. If you're not "locked-in" to a certain intake/carb combo you can pull 375 HP out with the 'right" parts. We were "locked" into using all the components to keep the above unit stock appearing. Thanks, Gary in N.Y.

(Add) I believe Elgin may be using CMC (Camshaft Machine Co.) to do their cams. Not 100% sure.

P.S. To those "durations" listed above, the L-82 has 224* x .450"/.460" x 114 LS while the 327/350 HP has the 222* x .447" lift x 114 LS. The L-82 is ground "straight-up with a 114 ICL, the 327 has 4* advance built in with a 110 ICL!
