160+HP 143ci Lowrider ST

Engine basics: 4.5" Bore, 4.5" Stroke, CNC Ported Heads with +1mm valves is all 4 corners, 64mm Throttle body & Intake manifold, 8.2 g/sec Injectors.

Cycle-Rama CR536 Camshaft. .536"lift, 250 degrees on the intake, 260 degrees on the exhaust, intake closes 50 degrees ABDC.

Screamin' Eagle Heavy Breather & FREEDOM Sharp Curve Radius Exhaust.

The last few power runs were done with the air filter removed as it was far too restrictive for the big 143ci engine.

I have to be clear & remind some people that I do NOT have full freedom to design & build engines for my customers, I can only suggest what I know to be the best. The final decision comes down to the customers own budget & preferences.
