Well I will throw out some grinds I was looking into. A couple of them were recommended by Predator-Z and Patrick G.

224/224 .609/.581 111+2 LSA xfi/xer Great torque cam will make peak hp around 6200rpm. Lope like a TR224 on a 112 LSA. Predator-Z spec.

224/230 .609/.604 111+1 xfi/xfi cam designed to run on beehive springs prefer PAC 1518's. Should peak around 6300 rpm with LS6 intake. Will pull pretty all the way around and a similar cam (113+2) made 430rwhp / 400rwtq in a 03 Cam only ZO6 Vette. Should sound nice with 5 degrees of overlap. These lobes supposedly run pretty smooth and are easy on valvetrain, quiet too. Idle (113+2) http://www.youtube.com/watch?v=cSeGEOPVrvs Another vette has this cam and has ran 11.20's in the 1/4, pretty proven if you ask me. https://ls1tech.com/forums/dynamomet...results-2.html

227/231 .614/.617 111+2 LSL lobes, Pat G recommendation to me. These springs are quite a bit harder on things and will require a stiff set of dual valve springs. Should make more torque and power than any of the other cams. 7 degrees of overlap will have a pretty nice lope to it. Also peak around 6300rpm.

So there are some choices for ya! Oh ya if you want the latest and greatest the LSL lobes are the newest craze.

Because of the duration, you would be fine on PTV clearance. Also, that is about the largest cam pertinent to this discussion. You can make more torque and only sacrifice a few HP up top by going a bit smaller.

As far as lift is concerned, there are several lobe families to choose from, just with Comp Cams. A few cams, centered around a 220/224, decending order of lift:
*There is little need for a lobe split as wide as the Thumpr series offers, 4-6 degrees is plenty for most N/A applications. The Thumpr exhaust lobe gives you an 8 degree split.

So there you have it, .102 spread on the intake lift and .098 on the exhaust give you all kinds of possible grinds to choose from. As stated in the other thread I linked to, if you are setting up a cam to go over .600 lift, .630 is not that much more. Yes you will have to step up with some spring maintenance, but you should expect to maintain them at .581 lift as well.

All the above information came from Cam Lobe Specifications Compilation and there are tons of lobe profiles available there. Look also at the .006 and .200 lift numbers for those lobes to get an idea of how the profiles compare. More duration at higher lifts for the same seat duration is key to making power up top without sacrificing all of your torque to a slow closing intake valve.

I think an LSL 219/223 .607/.610 110+1 or XFI 218/224 .605/.600 110+1 would make lots of power everywhere, and do a great job at what you are trying to accomplish.

Good luck!

Now that is the kind of information I was looking for! Thank you very much. Now I can pick my cam.

TTT - what did you decide?

thats a great cam and makes good power. i had a custom cam made for me 228/232 .588/.595 110LSA which brings the power band down some for more low end torque!! great powerful cam IMO and are on comp X-ER lobes

I'm thinking that xfi 218/224 looks good.
