My can was a 224/227 .563 .569 114 lsa with some home ported ls6 heads, and a 3600 vig. unlocked. I also have ls7 lifters from ac delco and i run 7,000 with no float. Are you sure you are floating the lifters? How do you know this? Usually its either valve float or lifter pump up. If you get the ls7 lifters they take high rpm a lot better then ls1 or stock lifters.
What maf are you running? Hope it isn't stock. If you have the fast intake like your sig says then those openings on the tb is 90mm and the maf is 74mm. I run the 85mm truck style sensor and even then you should go bigger. I think someone offers a 100mm billet maf meter.
If you do end up going to a set of ls7 lifters put a cheap set of ls6 heads on ther if you don't already have'em

Yeah, I have a stock MAF sensor. I do have a ported fast 90 and a 90mm TB
I have patriot double springs, my tuner says the car is floating the lifters, and garentees me thats the issue.. they are stock with 118k on the car.
I want to do lifters, and heads at the same time... but, I have a 98 so i'll need coild brackets and vc's too.
