Thread: Will a GM HEI Distributor fit a LR/RR V8?

Thems the ones from memory it's 1977 Cl model up to 1982 late CM models.
The module cost $80.00 last time I bought one but this was many years ago. If you go that way stay away from the chrome ones. They had problems.

[QUOTE=Brian Hjelm]Stayaway from CM ELB systems. They incorporate an emissions control system that organises the ignition advance map to limit emissions and in the process, performance. They also have a habit of getting a bit tired in the little electronic components, and, typically, you end up with a top speed of 80-90K's and a humungous thirst. They also incorporate a limp home mode which clicks in when the main system fails but they dont incorporate a means of telling you about this. You notice from the fuel consumption and lack of get-up and go. The CM distributor has no advance/retard functions, all this being done in the ELB box. The CL system with pointless distributor, vacuum & mechanical advance, and Chrysler electronic ignition module is very good. The aftermarket electronic ignition modules are not as good as the OE one.

Costs? CM type ELB module, now made by Boeing, over $600 last time I priced, some years ago. CL (OEM) type was around $200 over 15 years ago.

I should add to the above, that all CL sixes had Chrysler electronic ignition, as did early CL V8's. Late CL V8's and all CM's, sixes and eights, had ELB. The ELB is an excellent ignition system, but the inbuilt emission control system, which can not be isolated or removed, emasculates performance. These are Bosch distributors and may be an easy conversion to the RR/Buick/Olds V8. Get the ignition wiring harness off the wreck with the dissie and module. My choice, however, would be the GM HEI system. It is a bloody beaut, and self-contained. disconnect a plug wire from one and hold it, well insulated, away from the plug and see how far it will throw Tesla like sparks.
