I have a 99 5.3 just wondering if i should upgrade my throttle body to like a bbk?

 

if you have the cash to blow. just port the one you have a little bit.

 

No... just port the one you have.

 

Terminator, Do you think LS6 heads are probably the best way for me to go. The 6.0 heads would do good in 5.3 block? What about pistons and all the other stuff along with it. Where do u think is the cheapest place to buy them?

 

i will probably get shot at for this, but, from what i hear, the 6.0 heads flow better and can be easily found and less expensive. i got mine complete with awesome port job, etc. for about $2800 out the door. as far as your other parts, like i said in another post of yours, just shop around a bit. prices will fluctuate from dealer to dealer and time to time. not all suppliers carry all the brands out there so that will make it that much more of a challenge. do you have a brand in mind for any of your parts? do you have the ability and resources to build it yourself? if not, ask your builder. they will all have different opinions. i am very happy with the guy that built mine and he has made many very good suggestions along the way.

 

well what heads and setup do you have, if you dont mind me asking?
