It is threads like this, that will make it so much easier for those of us who haven't yet moved up to the bigger TC engines. Thanks to all for the information.
 
I just had a look at the DME 575 cams and the specs of 42* intake close and 248* duration make it seem like too big a cam for my liking without other engine mods..... Of course I have no idea what they perform like, but just on the specs I would say its a "hot rod" cam.
 
Yep... you just can't lose with the SE 204, its a proven great bolt in cam.

One thing to remember with this thread is that not everyone has the Jackpot 2-1-2 headers and a great tuner like Jamie et al. So the results of the tested cams used with other components etc possibly won't be as favourable. JMHO.
 
My goal is to get the most out of my 96" without stressing the crank or the valve train. If the TW-6 or 555 is acceptible for this than thats ok but if its too much for my stocker(fat cat with open aircleaner) than I will go for a smaller cam plus the old girl has 73,000 miles on her.
 
Don't worry about the crank. You're still a long ways off from having to even think about it.

If you don't want to raise your compression or mess around with your heads, there's a handful of true bolt-in cams that will increase your performance over stock.

To get true performance gains, though, you'll need to consider increasing displacement and compression. Even at 96", if you can increase your static compression to 10.2 or thereabouts, you'd open the door to a lot of higher performance cams. At stock compression, you're more limited. A Woods 6 is a good cam for the 96, but is happier at 10.2 static compression. You can get there with your motor, by running a thinner head gasket and milling your heads to make the combustion chambers smaller.
 
Soooo the woods TW-6 is ok for my set up.Is the 555 to much of a stressor to my stocker? I do have a sweet mill in my shop (1958 brown&sharp series 2 I think) but I think I will wait to deck my heads till spring when the shop is slow.
 
Yes the TW6-6 will be fine..... but after Jamie just proving that the 555 would be even better - why not go for the 555??? It will also be fine for your set up and will also respond well to increases in compression or displacement down the track.
 
Yes, I agree the Woods 6 and probably the new 555 both are "happiest" with an increased compression ratio over stock.... but Jamie's tests just proved that even at stock compression in a 96" motor you can get true performance gains without having to increase either compression or displacement. I think that was really the whole point of Jamie's testing of these cams - to see real gains without touching the motor. Over 100 lbs of TQ and around 96 HP I would definitely call that a performance gain over stock. Hell, some 103" builds don't get those numbers!!
