Car was previously just a 5.3 with cam and tc78 which only satisfied me for a few weeks till I decided I needed to step my game up! That combo is going in a clean G body tthat I will do later!
Engine:
Iron 370

Induction:
Holley Hi Ram 92mm to Stock TB
6 Bolt Trickflow Genx 255 ls3 heads
ls9 Gaskets

Alot of people are curious about the heads that what they flow. these heads actually have a smaller intake and exhaust port than the factory ls3/lsa heads and an even smaller port than all of the CNC'D rectangular port heads. here is a little info on the heads if anyone is interested.

Includes Billet Rocker Arm Rail Mounts for use with OEM LS3 1.7 Rocker Arms
Uses Powdered Metal Valve Guides
Requires longer Pushrods (7.750")

Damn that going to be my build almost exactly! , I'm excited to see your build and results.
Couple of questions. Are you retaining AC or no?
Also what do you have planned for cooling?
And last is that the Mahle speed pack with rings you are running or another piston of theres?

This is the Non AC kit version
Cooling as in radiator or intercooler?
Honestly im not sure if its the speed pack but it is their 4032 forged piston and its coated.

I believe his screen name is bergers or something like that. I purchased them bare for around 400 bucks. As far as I remember he gets them very often!
This week we will be removing the cowl trim to drop weight and make room for the intake. Will post pics as progress moves along.

Well a little update!
I got a wild hair up my *** and decided to have the LSA heads sent off to TEA for their CNC program since i thought it was a heck of a deal! Also decided why not send my s480 to Forced Inductions and have them turn it into the baddest 80mm available with their billet wheel upgraded!

yea between the wheel upgrade and cnc work on the heads i spent right at 1k and i think it was money well spent!
Im not really to sure what to expect out of this combo but i would like to go 150 without really pushing it!
