Does anyone one on the list have experience, figures or running similar setup
on the approximate: -
1. Static Ignition Timing
2. Idle Advance Timing
3. Distributor Advance Curve
that will give a starting point for a TR4 engine bored out to 87mm, 9:1
Compression ratio, Running on LEADED/REGULAR Fuel, 45DCOE Webers (34mm Chokes,
4.5 aux. vents), Large Inlet and Exhaust Valves, 'Mild' Cam (70/30 Grind), STD
Lucas 25D Distributor (Converted to Electronic Ignition), NGK BP7ES Spark

Any assistance/information is greatly appreciated.
