PRC 5.3 Stage 2.5 heads w/ 59cc chambers installed Netted 39 rwhp and 19 ft/lbs.
382.9 h.p. and 387 ft/lbs.
Eastside did the install and tune. Thanks Eastside.
Really pleased with the car. Pulls like a raped ape. Wife hollered:
HOLY ****! when she punched it at 25 mph.
Definately need better rear tires.
I'll post the graph tonight.
I know I lost 21 rwhp when the converter was installed.
Car with exhaust and lid:
299 rwhp/320 ft/lbs
With converter and headers:
302 rwhp/332 ft/lbs
With 228R cam:
344 rwhp/368 ft/lbs.
With heads:

I have to pass a visual and OBD11 emissions inspection in CT so the Fast intake and throttle body are out-no EGR provision. The guys at Eastside weren't too keen on the Fast intake, either.
I could get a pulley and LS6 intake which will net 10-12 h.p. in the future and that's about it.
Need stickier tires first.
