Heads Question

[daddy's_playing_again]

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?

[skeet]

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?

[daddy's_playing_again]

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?

[daddy's_playing_again]

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?

[daddy's_playing_again]

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.

[daddy's_playing_again]

So 4:10 gears really are do able??? building what I wrote above, where would that put me???
