LSX Blower Cam recommendation Any suggestions for a streetable cam for this motor in a 6000+lb Avalanche. Hoping to mount an Eaton TV 2300 blower on top of it. Will be going to an 80E trans. TC stall speed yet to be determined.
*edit: see post #4 for motor spec's

LPE GT2-3 207/220 .571/.578 118.5 or maybe even an LS7 (211/230). I mostly tune my own stuff, but I can't imagine getting the driveability of a big cam right on a blown tank like you have. I would stick with something small, but that is just me. Most of your power is going to come from the blower, not the cam anyways.
I had the GT2-3 in my Firehawk and it idled stock but pulled hard. I had a powerdyne on it too, and the low overlap made the blower shine. I have heard it is a popular cam with the truck guys too. Just get some good heads to take advantage of the lift.

The GT2-3 is a proven performer. I just think it would be a little small for the

THe cams you listed would be completely wrong for something like that from what I would guess youd be trying to do with it. What exactly would you be trying to do? Picking cyl head first would be paramount... then look into cams

No. I could use some more detailed info on this blower. Don't see a performance map posted for the R2300. http://www.eaton.com/EatonCom/Market...Maps/CT_139366
Then who knows if it will ever become available in a LS7 style configuration. Harrop says they just bumped their's back another 6 months. Might have to rethink the FI setup.

I have now come across a few "blower cams" with between 4* and 6* of overlap. Here's one from EPP: http://www.exoticperformanceplus.com/movies/sts1.mpg

What would big overlap do to the bottom end where the modified roots blowers normally shine?
