Im taking the Flat Black FB for a dyno run monday
Im trying to guess what it is any one wanna chime in?

12A Stock engine Ports
Nikki (kentetsu modded) Carb
Full Polished and ported Intake with coolant block off.
Racing Beat Header and custom exhaust NO CAT NO Muffler
4.11 GSL Rear End
Cut Gear Tranny Stock Type Gearing
Stock Ignition Set up
Front mount oil cooler
Stock air cleaner

Im guessing about 115hp-150hp

I may be way off but this thing moves.

 

No doubt you've got a good motor in there. That's the one that was originally an automatic, right? Be interesting to see what kind of numbers it produces...

 

Running a header back, with straight pipe? 105hp.

 

FYI all GSL rear ends are 3.909, some of the SE rear ends were 4.10's and some were 3.909

 

105-110 rwhp at about 6,000rpm
