I wasn't expecting five volumes but thats fine by me.

Manuals are for year 2003 chevy/gmc.

I'd be happy to answer any questions via manuals for those in need.

One curious thing I was looking at engine specs for LQ4 and LQ9. only internal difference I saw was compression ratio. both have the same cam specs. I'm sure evryone knows about that already though.

peace

 

Did you order from helm.com or the address/phone number in the back of the owners manual?

Thanks,

 

Its amaizing how much difference a little compression can make. Add better flow to it, and youd be surprised what any LS1 would do.

 

2001HD, I ordered them from Helm, no problems.

 

hoe much?

 

Order online or 800 number ??

 

$120 + Tax + Shipping Total = $135 and some change.

I ordered online.

 

What is the exact website for those manuals?

 

Very cool! Save that $70/hr for yourself.

 

i ordered that same manual over 2 weeks ago from helm and havent gotten mine yet!
