Looking for a cam for my afr headed 355. It will have long tubes, 190cc AFR heads, 2800 stall, and about 10.5-1 compression. I was thinking about Traxions cam. What do anyone here recommend??

Without a doubt go hydraulic roller.

TPIS' ZZ9 (kinda pricey though) or Lingenfelter's 219/219, which is one step up in duration from the ZZ9. Accel makes a good one too, but I don't recall the number.

CompCams makes several excellent profiles too. Check out their site at CompCams.com

Don't exceed 224 @ .050; shoot for 112 Lobe separation angle and get as much lobe lift as you can. Too much duration causes vacuum problems which won't let your brakes work properly, requires a higher stall speed converter, probably will call for a modified PROM and will make your idle pretty lumpy.

Also you'll want the aggressive (fast)intake ramps like those on CompCams Xtreme Energy Series.

Look for split duration with more exhaust duration than intake, especially if you have a rather restrictive exhaust. Although the 219/219 isn't a split duration profile, guys rave about it.

Of course if I had an idea of how you plan to use the car, I could be more specific. I assumed street performance.

Hope this helps.

I'm doing a similar engine, and the cam I'm going to use is the comp-cam #8-305-8. Hyd roller.
