« on: February 04, 2012, 05:57:12 PM »

New setup!!

Scat/eagle -2cc diamonds
LSA ported oil pump
New cam 247/262 .632 .596 115 +4
Powebond 25% UD pulley
All new gaskets and seals

New top end where I spent the $$$ haha

TFS 235s 64cc for 11.89 comp
Yella Terra non-adj roller rockers
Ls9 head gaskets
Fast 102/102 ported and port matched to the 235s
Return style -8 fuel system with A1000 FPR,billet rails and 400lph walbro
Ford 42# green tops
Samberg rad/intake with ls7 maf elbow
Hinson/stainless works 1 7/8 LTs
3in or/y pipe with 4in single dynomax bullet.

Also changed to the following..

McLeod RXT twin with 18lb spec billet flywheel
Still no AC/PS,HVAC
Samberg 8.8 straight axle with 3.73s!


OLD SETUP

PRC 66cc stg 3 317s 2.08/1.60 324 cfm@.600
.051 gaskets approx 11.4 comp
Fast 90/90 ported AND port matched to heads

Bottom end...

Ls2  block

Its always good to be conservative, but that thing better make all of 500rwhp. 

Make sure you get some good valve springs on there and do something about the rockers.  Either have CHE bush them, comp trunion upgrade, or some aftermarket ones.

Trunion upgrade is being installed and valvesprings were tested.

500whp NA is a tricky sombitch. Our baby 393 with the fast 102 and cnc'd 243's and 247/251 cam only made 507.

I bet now with out bigger cam it might make 530ish.
