Jeep Strokers

Hi,

Just completed 4.7 stroker with following parts:

HESCO MPFI, 1994 ECU
7120 Head, port matched to exhaust and intake
2000+ Intake
Roll Master Timing Chain
4.2 Crank
4.0 connecting rods
4.0 Renix Block
Keith Black KB424 +0.060" bore pistons
Bishop Buehl Racing/ CompCams 68-235-4
Bishop Buehl Racing valve springs
Victor Reins.043" head gasket
0 deck quench
Meling High Flow Oil Pump
Ford Cobra 24 lb injectors
Holley Adjustable Pressure Fuel Regulator
62 mm Throttle body

jCC'd the head and it's 57.6 cc's.

Static Compression: 9.26/1
Dynamic Compression: 7.8/1
Intake valve closing angle: 58

Considering going with GM ECM (#1227727) and using TunerPro to make adjustments.....although, I don't know if its worth it vs staying with stock ECM and adding adjustable MAP.

The engine runs pretty smooth and starts well, but I wonder if I'm leaving power on the table without specific tuning. I'm not going to add supercharger or turbo.

Thoughts?

A SBEC2 to JTEC (96-99) conversion harness can be installed then fully tuned with HP tuners. That will leave you room to grow if you decide you want to add forced induction.

Thanks, I'll check into this option.
