Just to be clear, there are several aftermarket options in play:I know this might sound silly to some of you, but....what is the difference between the centerline distributor, the lesser expensive 123? o and Andrew what is a Marreliplex ( a later style electronic one or an A/M one)? I guess one might one distributor to have some adjustable curves correct or is A STANDARD electronic one just plain good enough of an upgrade, that will give a guy what he needs to drive it hard once and a while? Again I appreciate every ones help...
1 - Install a Pertronix kit in a stock Bosch Dizzy for $119 (Summit). Best bang for your buck if you've got a descent dizzy. Mechanical (stock) advance:
2- Buy a Pertronix Distributor for $181 (Summit). Don't know anything about it but is a good price if your stock dizzy is worn:
3 - Buy the Centerline Distributor for $269 (Centerline). Not sure is there is a difference between CL and Pertronix. My old ID405 had a pertronix module in it. Assume mechanical advance:
4- Buy a 123 fully Electronic Distributor for $324 USD (Classic Alfa). There is also the Vac version (+$14) and the programmable (+$86). The non programmable units have a bunch of different curves that you can choose. The programmable version is, well programable. Great if you do a lot messing around. Not much point if you are sticking with the stock set up as you originally stated:
Any of these are better than a 40 year old stock dizzy with points and condensor. There is the Marreliplex option as well but now you've got outboard electronics and still old technology and old equipment. I've got several sitting on a shelf - make good paperweights IMHO...
