Best cam with a 6x2

I just purchased a 6x2 intake with holley 94's to use on the 383 stroker in my roadster. I am planning on running progressive using the center two as primaries. From everyones experience what is the best style of cam to use in this application? The engine is a 383 with 9.7 to 1 and ported 2.02 camel humps. Auto trans with 2k stall and 3.50 gears. Do I want a mild grind to build more vacuum or something more agressive to work with the higher rpms? Its not going to be a drag car, just a fun weekend driver. Comp cams recommended a XE268 when I was going to run the dual quad manifold, but I would like to use something that would really compliment the the 6x2. Thanks in advance!

 

Not an expert opinion, but I think you are probably in the ballpark. The stroker motor might tolerate a little bigger cam, but this one has a reputation of pretty good performance, combined with tractability on the street. I think it is probably well-matched to your combination.

Of course, if you want it to be like an old-time hot rod with six deuces, get the biggest cam you can. It probably won't run as well, but will have the right attitude......

 

Considering the overall CFM ratings, dual quads vs 6 X 2, the difference is probably minimal. I agree w/animal, it's fine. You'll probably feel a better kick in the ass with the 6 X 2 than the 2 X 4 if you get em dialed in right.

 

Thats good to hear, I really like the specs on the cam and it makes huge torque. I just didnt know if I needed more vacuum to get the 6x2 tuned. Anyone else have any good or bad cam experience with a 6x2 setup?

 

So what cam did you end up using?

 

If I was you I would stay with the XE268 but have it ground on a 106* Lobe seperation angle. The tighter LSA will cause the intake valve to close a little later and it will tremendously increase your low end torque. With that cam on a 106LSA you should end up with about 13in of vacuum which is plently for anything that you would want to use power brakes. The cam will sound great and you should have plenty of power with it. Just call up comp cams and ask them to grind that cam on a 106LSA last time I had it done it only costed me about 165 bucks.

 

Ended up selling all of the sbc stuff and built a Hemi for it. The 6x2 went to Australia! I did learn that the XE cam makes great power but is noisy and closes the valves very quickly. I think the Lunati VooDoo is the way to go when it comes to the new style of cams.

 

Earlier, not later. 110 to 106, 2 degrees earlier.
