I have a set of stock untouched LS3 heads (Casting #821) and LS3 intake manifold. They both have less than 8,000 miles on them and were taken off today. I'm selling them because I'm stepping up to the TFS LS3 heads. The heads have the PRC .650" double spring kit on them that includes the ti retainers. The heads have the hollow stem intake valves that weigh in at 88g. The intake manifold comes with manifold bolts and gaskets. I also have zero mile LS3 valves springs if some one wants them. Let me know if there are any questions


LS3 Heads Assembled - $650
LS3 Manifold - $175
Stock LS3 valve springs - $50

 

Do you have a fuel rail for the intake? How much shipped to 62002?
Thanks

 

Damit. If you have this in 2 weeks it will be mine. If not ahh well. Just got my truck back from paint.

 

What's the difference between the ls3 an ls6 intake?

 

I am using the stock fuel rail on my FAST 102. The LS3 intake comes just as pictured without rails, injectors, and throttle body.


Yea contact me when your ready man!

 

LS3 is a rectangle port intake where the LS1/LS6 is for cathedral ports

 

Is that price shipped then? If not, price to 62002?

 

Buyer pays shipping and fees. I will get a shipping quote tomorrow for you!

 

I meant flow wise, would a ls1 like 243s & ls6 intake or ls3 heads an intake?

 

LS3 heads won't fit on an LS1. They require a 4" bore.
