Question

I've got a '68 Camaro with an inline 6 and was thinking of running an electronic ignition on it to help smooth it out. It runs good otherwise, and I'll be using it until I eventually put in a V-8. Are those Pertronix units any good? Or maybe a Mallory or MSD box? I'll be switching it over to the V-8 when I swap. The new V-8 will probably be mostly stock with a few mods, so I realize that more performance with the new ignition will probably not be too noticable, but I'm looking for smoother running and better burning anyway... Any experience with any of them? How about Jacobs?

If you don't want to spend alot of money just buy a MSD 6A but if you plan on buliding a strong V8 I would go with the Mallory Hifire V1 very similar to the Digitial 6AL except no expensive chips to buy plus it has a window switch and is cheaper.Like I said for a moderate motor the 6A would be sufficient and you can pick up a used one cheap.

the only diferance in a MSD 6A and a 6AL is price, and the 6AL has a rev limiter built into it. the box's are the same except the rev limitor.

i have a inline 250ci 6 banger in my camaro. i have recurched this. you have only 1 realy good alterative to the point's. a GM HEI out of a later mondle inline 6 banger. i do not like the petrox unit's as i have had to replace them too much on fork lift's. in fact this is what they are for. the company wanted to make more money off a cheep poorly desienged system, so they hyped the heck out of it and have made a ton of money.

the petrox system dose not improve perfromance, spark voltage or milage at all. an HEI or MSD set up will, but the MSD can be trigered by the point's or a HEI set up.. i have seen people use a petrox system to triger a MSD box but the point's or HEI work beter. also point's last 100% longer with a MSD box. this is because they see a lot less voltage so do not whare out as fast.

if you get a MSD box you can use it with a V-8, but if you get a 6 banger HEI it will not work with a V-8. if i had the money i would get both a HEI and a MSD box and use the HEI to triger the box. then when i put a V-8 in, use the box with that motor too. but get a MSD distributor to trigger the box on the V-8.

a 6A box is about $130.00. a 6AL box is about $170.00. the HEI is about $20.00 to $50.00 at a junk yard. you will need a MSD coil with the MSD box, the external is the best. it is about $30.00 to $50.00, and a kit to convert the HEI to an external coil is about $50.00. you can use the this coil with a V-8 too.

hope this help's ya out. i do not recomand any other CD box's cept MSD. i have seen them toast out too easy and they are not made as well IMHO.

HEI,cheap,and works well.You will have to change the spark plug wires.GM has been using them forever,seldom break,and if it does,parts are easy to find.The E core coil is good for 40-50 thou. volts.Only if you have a badly tuned engine,will it need that much spark volts.

I use Crane's XR700 Electronic conversion. I use the stock distributer, cap and rotor. No points no condenser totally electronic.

I have had no problems with any of my electronics.

So what late model 6-cylinder HEI will work? Is it a drop in, or will I have to modify anything or change gears? Modifying isn't a problem, but what ones are the best? (years, models, etc.) Thanx for all the help so far!!!

Mine can out of a 292 truck engine there is a short extension on the bottom that must be removed {take out the pin}the 292 is a taller block. I would suggest that you put an advance curve kit in it{the V8s work} mine must of had full advance about 10,000 RPM

HEI is very good and simple to install. If you are interested in a MSD 6A I have one I just removed from my Camaro that I'll sell for $75. There is nothing wrong with it, I just upgraded to the new Digital 6 Plus. I also have the Blaster 3 coil I'll let go for $20. The HEI may be good enough for what you want.
