No problem Glad to help.
I would call CamMotion if it was me and get a custom ground cam exactly to your specs. Be prepared though they will want EVERYTHING...... comp. ratio,piston to deck,head gasket thickness,camshaft,head flow #'s,gears,tire dia.,convertor,weight of car,vin and social security # ect.Don't be afraid of the bottle!!! Be afraid of your tune!!!

The LS7 lifters you are talking about I just got from my GM dealer for $115. I just put a compcams cam in my car it is 230/236-.613/.608 - 112. They say the lifters are good to 8000. A week later I get the new 2007 GM Performance Parts Catalog, and what do they have? New, just came out, Racing Hydraulic roller lifters. I'll copy what they wrote " As developed by GM Racing and GM Powertrain, For use in Gen III and IV engines where sustained high rpm's are typical, Special reduced-mass internal components allow for higher limiting speeds with aggressive camshaft designs, Improved valvetrain dynamics and stability will improve horsepower, and high rpm's, Tested to 8000 rpm in GM Racing applications". Part #88958689. They sell for over $300.00, but my dealer said he could get them for around $270.00. I won't be buzzing mine over 6500-6600 anyway, but the lighter insides and different bleed down might of gave me a few more hp. What do you think of these? Gunny
