Hi all,

Just had my 351C rebuilt.  It was a stock 2V and I am upgrading to 4V.   Cylinders are bored out, higher compression pistons, lumpier cam, etc.  So I need to choose all new electrical.  There are a dizzying array of distributors, plugs/wires, coils, etc.  I am overwhelmed at the choices.  I had a Pertonix Ignitor in the old 2V setup and performed well with no issues for many thousands of miles.  So I am somewhat partial to them, though certainly not married.  What does everyone recommend as far as choosing what setup setup to use?  What all components do I need and should I stick with one brand?  Or better to mix and match?  Any and all advice welcome, I'm very open-minded here, and have much to learn!  Thanks!

any reason to not re-use the Pertronix?

seems like it'd be a nobrainer since the car is wired and you know it works

I would think I'd want to upgrade/replace my old distributor, coil, plugs, wires, etc...no?  I wouldn't want to re-use that stuff, it's many years old and has many miles on it.  Plus the engine has received a significant horsepower upgrade.  Not sure if that matters, I would think it does.

I have a MSD distributor and 6AL box, Very happy with it.  I've also run the DUI setup on My 351W, don't know if they have them for the 351C, but they work well also, and very easy to hook up.

You can run a MSD box with a pertronix if you wanted to, and reused your old distributor.  Just check the bushings for free play.

i'd worry more about the location of the gear on the shaft and the required free play for it

1 major reason i'd stick with a known good / working piece that you already own is because the aftermarket can't get the gear on the shaft in the right place and new out of the box distributors are chewing new cam gears faster than Censored

FWIW i don't know how much more upgraded you're gonna get?

unless you go to a multi coil on plug type ignition ... i'd keep it simple

one consideration is can you get parts at Walmart?  goal for stock Duraspark

whatever you decide on, check for oil clearance / free play travel between the bottom of the dizzy gear and the block ledge before you install the timing set. the dizzy hold down bolt needs to be snugged tight as it would be while driving or the O ring will hold the dizzy up and fake clearance

i just remembered Tim Meyer / Trackboss products is working on a stock appearing dizzy that uses a GM module inside, again goal for availability anywhere.

can also be used with a multi spark box

Some of the replacement Duraspark boxes actually have a G.M. HEI module inside instead of the Fork guts.
The above post should be read in a "Grumpy Old Man" voice.

This is what I want for my car.  However, Tim hasn't given me a clear answer on when or if they will be ready any time soon.  If one is ready by the end of my build, I am going to get one.  The GM HEI modules are a dime a dozen, and cheap enough to carry spares.
 
Otherwise, I am probably going to go with a home made Duraspark HEI setup like Todd did on his car.

it does seem like the dizzy is on the back burner, minimum. Tim's web page is scrubbed of public access to any of the posts about it and my post in the 335 section goes to his 'private' message

but yeah the quality GM modules last a darn long time too! for my hundreds of $ personally i don't need a family keepsake dizzy housing, a factory housing can be polished up pretty spiffy and sealed in clear FTW

Since your leaning towards the GM HEI, here's the one I run on my '79 t-bird, but for the 351c;


They're great setups, mine works with the factory tach, and they're just about drop-in.  I incorrectly called mine the DUI setup, which is WAY more expensive.

I'm told the pertronix is a good set up and easy to work with. I eventually settled on a modified Duraspark distributor but I'm not running a 400-500 horsepower car either.

I was thinking about gutting a Duraspark box and going that route.

Is the '79 two or three wire?  I just remember hooking the tach lead under the hood to the tach terminal on the cap and it worked, and was accurate! ClapThumbs Up

Vince, if you go that route(been extremely happy with mine so far), get the 5-pin HEI module from an '80 Oldsmobile Toronado w/307,  Standard Motor Products part#LX330. Works just like the 4-pin but with the 5-pin if you send a ground signal to that 5th pin it will retard the ignition timing 5 crankshaft degrees for as long as the ground signal is present. Makes for much easier starting even with 18-20 degrees of initial timing.

Yeah, It's a Hybrid...It burns gas and tires.

The '77-'79 tachs are 3 wire.

I totally agree with using the GM module(and I H8 GM), much easier to find and the aftermarket pieces are generally more reliable for the HEI modules than the Duraspark boxes, at least in the "Blue" strain relief versions of a DS box.
