SuperVic Jr intake

I don't think I ever posted up what mine made last go-round. Few changes were made when redoing valve springs and brought down the CR a bit from being higher then expected before. New exhaust setup, and some cooling mods will be going on in the next few weeks.

355ci - 11.8:1 CR
ported stock castings
hand ported intake
Holley 58mm TB
Lunati 231/239 .570/.585 110
1 3/4" headers/ORG/GMMG
T56 - 3.73s
!AC - EWP - UDP - LS1 lid

EFI 24x setup
Tuned by Alvin at PCM of NC.

422hp - 395tq

1994 Trans Am GT, M6, 100% stock except for Moroso CAI & K&N air filter: SAE 267.7 HP @ 5100 RPM, 310.8 LB-FT @ 3200 RPM.
Since then I have installed a BBK 52cc throttle body, 1.6:1 Comp Cams roller rockers, a new optispark, and a new catalytic converter. I hope to get it dynoed this year before winter strikes.

Basic 383 Brodix -18 headed LTx with a 300 shot. it made 53x N/A through a TH400 and 9in

If we had not burned the valve it should have went just over 900Whp. I hurt it the week before on "E" and this was trying to make the west coast shootout on C23.


new valves on the way pistons TBD

BTW That is at 6,600 It peaks at 7,700-7,900
