See Emissions DetailsThe Pro-Billet Ready-to-Run distributor is the perfect upgrade for outdated points distributors or bulky HEIs. Simply install the distributor in the engine, connect three wires, the coil and fire it up!
The Holden Ready-to-Run features MSD's adjustable mechanical advance which allows you to custom tailor an ignition curve to match your engine's needs. There is also a vacuum advance canister to help improve economy. For positive street performance, the Ready-to-Run is the best choice.
A maintenance-free magnetic pick-up accurately triggers the module. The increased output of the amplifier easily outperforms stock ignitions and will smooth out the engine's idle, improve starting and provide a much higher rpm range.
Includes a separate tach circuit that is ideal to trigger an aftermarket EFI such as an Atomic EFI system.
Features:
- Now includes build-in rev limiter!
- Supplied with an HEI style distributor cap and rotor (accepts Cap-A-Dapts)
- CNC machined billet aluminum housing and billet aluminum base
- Advance plate and weights are fine blanked from chrome moly steel and QPQ coated for friction reduction
- Vacuum advance canister for improved economy (can be locked out)
- Advance weight pins are staked and tig welded to the plate
- Easy-to-adjust mechanical advance with supplied springs and stop bushings
- Simple and clean installation with only three wires to connect
- Mechanical advance assembly can be locked out for crank trigger systems
- Powerful built-in module produces a 7.5 amp single spark through high rpm
- Does not require an MSD Ignition Control
- Maintenance-free magnetic pickup and precision reluctor create stable trigger signals throughout the rpm range
- Polished steel shaft is QPQ coated and guided by a sealed ball bearing
- Nylon pads ensure smooth operation of the advance weights
