Right now I have a 5.3 that will eventually be swapped for a 6.0. My question is would a set of cnc'ed trickflow 215's be to big for the smaller 5.3 or would i be better off with a set of cnc'ed 243's? :confused:

depends on what 6.0? lq9 or 4, for the money id just go with some 2.5 5.3 heads but then again whats the end result gonna be?
Right now I'm looking for a LQ9. I'm going to prolly go with the comp 222-224 566-568 lift cam and fast LXRt intake and 3200 Circle D converter. If I find the right 6.0 block first, i will prolly go bigger with the cam & converter. What is the 2.5 5.3 heads? I haven't heard of them. I just don't want to buy one set and then wish later I had have went a different route. I did that on a BB build I done several years back. Which ever head I buy I just want to go the best route and dont know a whole lot about the newer style motors.
What kinda times you looking to run or hp numbers?
I wanna go as fast as my decent mpg will let me. LMAO!!!! Seriously, I'd like to eventually see some high 11's. I realize that that will take more HP in a ecsb than it would in a rcsb.
It's not that hard I run a ecsb. Runs 12.6 on motor and high 11's on spray. Nothing really special about it either.
what kinda milage you getting out of it?
I have even concidered going 408. BUT i travle a lot, so i cant kill my fuel milage.
17-18mpg @ 70mph, 4:30 gears and 31" tall tires. I'd get the 6.2L truck topend and call it good.
So 4:10 gears really are do able??? building what I wrote above, where would that put me???:confused:
My setup.
04 chevy ecsb,LQ4,stock 243's milled .042,custom grind 228/233 .595/.578 113+4,90mm Tbss/Nnbs Intake,Pacesetter lt's,Dual 3" with Cutouts,Magnaflow,42#inj,Homemade cai,underdrive pulley,E-fans,278mm Circle-D 3200,PB lvl 2,tru-cool 40k,Eaton & 4:30's, 100shot
I guess back to my original question. would a set of Trick Flow 215's be to big for the 5.3 for now? I'm trying to get everything ironed out where all I have to do is start ordering.
Yes the 241 will work on the 5.3, but I'd go with 2.5 5.3 or the stock ls3 heads with l92 truck intake for the 6.0
Info for the prc 2.5's is here
