I got me a lq4 and I'm wanting to hit at least 450 rwhp in my rcsb! I ordered a thunder racing tru torq lvl 4 and I got some 5.3 heads I want to get fixed up! And I have a 3600 pi converter. What else will I need? Other than bolt ons.

 

nnbs/tbss intake and throttle body...i would think that would get you there, if not, nitrous is easy lol

 

do you think the heads are the right choice? and the cam specs are 227/234 .616/ .614 115 lsa.

 

you are going to need more head to reach those goals.

 

Are those. 5.3 heads ported and with bigger valves then stock ? If not then you need to get them. Ported and big valves ..... You might need a bit more duration on the intake as well. Imo

 

Yes the heads will be prc 2.5s! Which will raise compression! What heads would you recommend?

 

5.3 prc's stage 2.5. Are a good choince IMO .....

 

I'm gonna try it and hopefully it makes good power!

 

How much should i mill the heads to get the best performance? .030?
