Cam Questions. Ok I know these cam questions are getting old but I have a couple of questions. I have 2 cam sitting at work and I am trying to decide which one to use in my engine. If some one could help me out with the pros and cons of each cam it would be great. I am not looking for which cam makes more power but which cam is going to make more usable power. Here are the choices.
Patriot 225/229 .580"/.590" 114
or
Crane 229/239 .595"/.595" 112
Please dont suggest any other cams cause these are the 2 cams I have to work with. I will be using all the supporting bolt on mods and will be running a set of LS6 unported heads and manifold on my ls1 with this cam. Thanks for your help.

Well the cam will be tuned and I dont mind a lumpy idle. What I am looking for is which one will make more midrange useable power. I dont make it to the track as much as I would like but ever now and then I do some highway pulls from about 55mph.

Looks like more people are leaning towards the Patriot cam. Looks like I will be going this route. I just need to get some new lifters and head gaskets and bolts and I will be good to go. The heads I have going on are stock 243 casting heads. Should I get these milled at all?

i like the cranes duration numbers a little more...the exhaust duration is higher and for your application that may help. plus, the crane would have a more "lumpy" idle with its lsa at 112 rather than the 114 on the patriot. Both cams have lifts that aren't too radical, so you can't do wrong with either in that aspect.
I appear in the minority, i dont think you can go wrong with either though...but food for thought.

Thank you for your opion. These are the types of answers I am looking for.
I am still concerned about the 2 different duration spans between the cams.
i am going to do a little research for you..see if i can find some concrete info on exh duration near 240. i think you have good supporting mods to compliment that duration..your intake setup with the ls6 is good, and also i see you have some longtubes and ORY which is also a def plus..and certainly that crane can potentially make all the power the patriot potentially can.

I have a 90mm throttle boddy sitting around and an LS2 intake manifold also if its better then the LS6. I just have been reading that the LS6 is a better manifold and want to save up for a fast or something else.

With the mods you have right now, the Patriot is a better cam. Better DCR, better low trq for low rpm cruising, hardly any lope though.
The Crane is the other side of the coin, high rever, 10* overlap, nasty lope, will need a serious tune, 90/90 a plus.
Now seing that you have a 2000, I would do the Patriot, because your block is not going to like spining that high and if you don't, you'll be waisting your powerband.
bottom line, the Crane will need more safety, fuel and suppoting mods than the Patriot to work at its potential.

Stick with the LS6 intake for now... Until you can get a fast anyways. I see a lot of cars comming into my buddies shop making gobs of power with an LS6 sitting on top of some pretty nasty cam and head combos, and then only gaining moderate power from the introduction of a fast 90/90 setup. The LS6 is probably the best all around intake out there for most street applications that arent too radical.
Oh yeah, the point I meant to make... The LS6 does in fact flow better than the LS2 manifold... good for 6rwhp on a stock 6.0L GTO anyways.
