I just got my new LQ4 in today should i replace the head bolts from stock to ARP bolts before i get everything on ie.. turbo and intake or will the stock one's be sufficent for about 10 psi boost? Any thing else i need to know about buttoning it up before i get it all put togther be home in 26 days. Thanks for the help all. Learing slowly but surley. Dee

 

I would drop it in and go, I don't think your gona lift a head on 10psi.. Some will say to do rod bolts, but somany of us are running stock ones, I have never heard of a rod bolt in fact failing, something else usually goes first..

Even easier. Whats the ideal break in time for these motors or is there a ideal amount of time as far as miles goes? Trading my M-4 for a wrench in 26 days

 

Fire it up and run it!

 

If money is not a factor then I would go ahead and stud it as gm decided to lack the number of head bolts on the genIII's. Cause how long you think your gonna be running 10psi before you turn up the dial of death? Might was we do it while you have the engine out . Is it a crate motor? Might think about doin cometic head gaskets too. Rods bolts are not really needed unless your spinnin 7k+ rpms from what I hear.

 

Upgrade the valve springs or you will get valve float.

 

BADAZZ how do you like your tune from nelson i was thinking of going that route before i get ballzz deep in HPtuner? I might have to bribe thunder550 or vanilla gorilla to help with my tune when i get home. And the engine i have is out of a 2003 HD brand new sleeves rods and all internals Its been dynoed and all have to get my numbers from the wife not sure but the numbers are 345 HP at 365 TQ but dont qoute me on that, sound right??
