Hey guys, just about back from the sandbox so i figured i would start ordering some parts and etc for my 01 Z shell. Just picked up an 05 LQ4 motor from a member on here. I know the compression on these is about 9:5 correct? I don't plan on going FI, want to keep it NA for a bit.
My main question is which heads to go with to bump up the compression? I have read 243's or 5.3 heads will work great. Any recommendations on either or? I want to be just over or very close to 400RWHP/TQ through a built trans/4k stall.
I was thinking some 2.5 LS6 Heads/Torquer V3 combo. Just a ported LS6 mani on top of that until i get the built trans/9" set up in and full suspension. Then i will be going with a FAST set up.
Should mention i will be running the stock rotating assembly for awhile with just the H/C set up until i free up some more money, so this will be somewhat a budget build until i get moved and settled in when i get home.
Any suggestions you guys have to bump the compression and make some great numbers, or any other input is highly appreciated.
Thanks guys - Zack

What kind of car it was from ? I just put a lq4 from a 05 express an the only way it think you can check is the serial numbers on the block an see if it has alum heads and see if it has a cam sensor on the front cover. Not to sure right now Stressing just blew my ten bolt lol

I read through your whole build a week or so back, your build thread is actually the reason i pulled the trigger on a 6.0 instead of something else! Haha, what are the head's milled to? I was thinking of either the TorquerV3 or a Pat G speced custom ground!

I would have went with a custom cam from Pat G but I already had a cam kit from my old ls1 so I just swapped everything over. It was the Raptor cam from thunder racing. Ashamed too cause I put a spanking on my brother's cts-v then broke the crappy 10bolt.
