OPINIONS ON IGNITIONS SYSTEMS

[JERSEYJOE]

I am at the point in my build that I need to start thinking about a distributor and an ignition system. The easiest and cheapest way out is the factory duraspark set up but I am looking for a better way. I was inclined to go the complete MSD set up but I thought I would ask the experts here for opinions. by the way we are talking low compression 401, mild cam, 90% off road . I like the one wire HEI units for ease of instalation and lack of wiring. Are the MSD set ups worth the cost?

I looked at the MSD stuff but after speaking with MC a good point was brought up.. if the HEI coil goes out or something in the HEI unit.. parts are cheap.. and easy to find at any store. With MSD or the Stock stuff you may have to order it and wait for it to come in..

TFI.
Throw a cap, rotor, and plug wires from a Ford 460cid on there. Replace the stock coil with the Ford coil, regap the plugs and run it.

This only works if he has the Duraspark ignition on it. The older 79 and older V8's have the autolite style stuff that doesn't work with the TFI Upgrade.. A.. :-|

Very true...and all the more reason to upgrade away from Prestolite/points ignition.

I had the old Prestolite crap on my '77 401 and hunted down a duraspark dizzy for it as fast as i could :t:

The reason I dont reccomend TFI....ever is that the HEI has a hotter spark and gets rid of the stock coil, stock ignition control module and really cleans up the engine bay. TFI is like a nice meduim between the stock system and a HEI.

HEI Joe...all the way!

Talk to me about whose HEI Dizzy that you would recommend?

The reason I ask, for there are several folks building these.
Some I see eBay, looks scary, some, like ZMJeeps, looks like a nice unit.

Do you produce an AMC V8 HEI unit in your shops?
Now is the time for the sales pitch! hehehe

[jeepsr4ever]

I dont pitch but I will send you a pm
