opinions on cam needed

well after the cam or either with the cam im going to get some 243's or texas-speed's 2.5 heads. i may get the cam first and then get heads later, or if i can find a set of 243's for a good price i may pick them up too. i've read theyre proven , but cant always believe what you read thats why i posted asked first before i spend money.
specs on 2.5's are 2.02" Intake Valves, 1.575" Exhaust Valves, cant remember on the 243's. last cam i bought i didnt install cause my tuner said it didnt have much lift, it was a 226/229, .569/.572, 112 LSA

stalls have more to do with duration than lift I believe. That cam you have there has quite a bit of duration for a 5.3 and I would think you would want to go bigger than a 3200 stall. That looks like a pretty good cam for a 6.0 IMO. There are plenty of cams with around .600 lift so that is not too uncommon. Every one of EPS's truck torque cams have around a .600 lift. In short I would be worried about the duration more than the lift.

You sir are correct, as the duration increases, the powerband moves up. A cam that big in a 5.3 is going to need a ton of converter and gear...I'd say a 4k plus converter, 4.56's or more, and extensive tuning. We have members here who run 12's with a 5.3 and a TR220, 4.10 gears, 3200ish converter (IIRC), and stock heads. As 1slowz71 mentioned, sometimes less is more
BlueCajun ran a 12.48 I think it was with a TR220 and a Yank SS3600. For a 3200-ish stall I'd run a low duration high lift cam made for torque, for the cam you listed I'd run at least a 4000 although personally I'd run more.
