What cams will peak here?... I am looking into going back to a 4L60E and have read alot on how its the HIGH RPMs that tend to do them in, even more than the power will.
Unfortunate for me...my cam pulls right to exactly 6500. (231/237 592/603 111.5)....I have tossed the idea around of going with a cam that will peak sooner, and carry a better bottom end and midrange. Does anyone have any experience of what cams would peak around 6,000 instead of 6,500?

Really? Hmm. I know thats a very popular cam. Overall I am just trying to make the car more livable with a 4L60E rather than go all out with a TH400 or something. I know that shifting sooner would hut me with my present cam, but with a cam that made more power sooner, I would be ok.

A smaller cam dosent mean that your car will be slower buy any means.
If I was you I'd just get a built tranny and call it good looks like you have everything else. Except for some SFC's safty loop ect....

Why not ditch the 4l60 and go with somthing with more beef.
A built 4l60 can be pritty dependable but if you hit the track alot I'd probly go with somthing better.

6500 you should be OK if the tranny is decent. Prolly where I'll be shifting when I get my cam in next month and I am gonna be stock tranny + stall, shift kit and cooler. Get a good cooler cause the heat is just as hard on them as spinning high.

Hey I dont know how much money your planning on spending, but FLP has the Level IV for about $2,000. Its supposed to be very strong. If you go with the 4L80, keep in mind that you are going to have to spend more money on upgrading the connections to the tranny. It doesnt bolt right in.

spend the money on a stage 2+ 4l60 and call it a day. still alot cheaper than a 4l80 not to mention it weighs half as much. 
just look around you can find a good used one cheap.

228/232 .588/.592 110LSA+4 Should peak right around 6k
But, I have been told by a few tranny builders with 4L60Es into the 9s that a normal 4l60e with a cooler can definitely handle 6500. People have shifted them at 7k+ every weekend for a year hitting low 11s before failing.

i'll trade you a 4l60e with 80k on it for your t56 ... anyway...a 4l65e would be a fair compromise, but if you're really tied to the 60e then you're on the right track. there was quite a thread about this a while ago in the auto forum, it seems that the consensus was: rpms kill 60e's much faster than power will...get a 60e w/ shift kit and cooler, lower peak cam and sleep easy

Keep your intake valve closing point at 40 degrees ABDC at .050" and you'll be good (RPM wise). As mentioned the 228/232 110LSA +4 or on a 112LSA +5 will work great.
