I am looking at taken a 2003 tahoe and put in a 6.0 I would like to have roughly 450-500hp(at the most more like 475) at the flywheel. I already have an LQ4.

I was wondering if there is a smaller combustion chamber head that flows good off of like a 5.3 that I can get milled and maybe go with an ls6 style intake and a good cam( I dont really know what my options are in a cam). As far as cold air and header I am planning on that as well

I would like to have to do as little tuning as can. I dont know how tuning is required with these thing on big or small changes

I know on my syclone any little thing you really need to do some data logging to make sure it is gunna be ok

Thanks for the help

 

243 heads are cheap. and have 64cc chambers

 

dude if u put 5.3 heads on a 6.0 u will choke to death before u get to 475

u need a set of ported 243s or ported 035s
i have a set of the 035s in the fs section

 

243 and 035 is cylender head number(last 3) I am guessign

Post up a link to you FS thread

Thanks though

 

A good tune will be required to get those HP levels.

 

its the casting number it is on your head right rear corner facing up at you
