Need help finding a cam

My father is restoring a 69 Alpine GT fastback. He is in need of a GT camshaft. We called Sunbeam Specialties and they do not carry the cam anymore. Do you know where we can find one? It has to be a cam for a twin carb aluminum head 1725.

Nice looking GT!

You should be able to use a Series V cam, either stock or having it ground to the slightly milder GT specs. Delta Cam in Tacoma, Wash. can put any grind you like on the cam for about $50. You'll find several threads here re Delta Cam.

We picked up a cam from a forum member and think we have ran into another problem. The cam that was in the engine is definitely wrong on the middle two cylinders. The exhaust and intake is opposite from the cam we received from a member here. But now we discovered that the oil pump drive gear is different. The one that was in the engine is a 11 tooth and the one on the cam we purchased is 12 tooth. What should a 1725 aluminum head 1969 alpine have 11 or 12 tooth? Beginning to think we still have the wrong cam. Any ideas??

That will be different to what you have for 2 reasons.

1) The pump drive gear has a different number of teeth between the 3 main and the 5 main engines.

2) The cams for an iron hear versus cams for an alloy head have the valves in different locations, just like the intakes and exhausts differ in port positions.

It sounds like in your case, you couldnt possibly have bought a more wrong cam for your engine.


There is absolutely no reason you couldnt use a series V alpine cam in that engine. No its not exactly the same timing specs as the hunter alpine engine, but its close enough and much easier to find.

YMMV

ok so we have a 5 main engine aluminum head dual carb. Tell me if I am wrong but I think we need the following cam:

1. for a 1725 5 main
2. 11 tooth
3. dual carb
4. aluminum head
5. prefer late model...seems like I read somewhere that the later ver. has more lift.

Does this sound correct and does anyone have this "needle in a hay stack"? It's all we need to finally get this thing running.

When you say "late model", the only models that are applicable to what will actually "run" your engine are a series V (1725) cam, or an alloy head, twin carbed sunbeam "hunter" alpine cam.
As the latter are rare in the US, go with the SV cam as you will find 100 of those for each of the hunter cams.
If there is any difference in lift, it will be minor.
More HP will be gained in a carb change than in the camming.

Very good info. Any ideas where I can find a Series V cam?

With all due respect Jan, your response to George reads as a bit harsh. This is the first I've heard of an issue with Paeco as I'm sure it is with George and others. Care to elaborate on any problems you may have experienced?
