i just got done doin a LQ4 swap in my RCSB 2wd heres the specs

06 LQ4 stock lower end
ADVANCED INDUCTION 243s milled to 60cc 11.1 comp
ADVANCED INDUCTION custom grind 226/230 605/600 111lsa
stock truck intake for now hopfully either a TBSS or a fast will come later
44lbs marine injectors
LTS true duals 2.5 flowcrappers x-pipe
3600 stall fully built 60E
4.10s true trac

 

you 3" true dual? if not you need it

heads worked any?

nice setup should run rather well for ya!!

get a ported TBSS intake or have one ported, it'll out perform the FAST truck intake

 

Sounds good now for a speedo and burnout vid!

 

Yeah Dave I sent the heads to AI there fully ported and polished 5 angle valve job milled .030 manley nextek springs. I might just need those 3 inch duals what type of mufflers
