I'm looking to upgrade the spark after rebuilding my 454. With all of the extra flow thru my heads, I'm fearing that the car is running rich and the fuel is not burning completely. I've seen drop-in electronic ignition systems that do not require the "box". Does anybody have this distributor system, how does it work, does it perform well and finally, does it fit under the ignition shielding?

Thanks in advance.

not sure which one your thinking of, but you can put a control box in the car and run the wiring threw the firewall to the dist., i'm woundering if the
Pertronix is what you may want????

IMO, the aftermarket point conversions make an otherwise reliable car unreliable. If I wanted the stock look, I'd go here: http://www.davessmallbodyheis.com

You want Pertronix

I think it's spelled "Per-stranded" for it's infamous reliabilty record. Also does not (by design) provide any better spark than the stock system. :cheers:

I put the Mallory Electronic Ignition in mine about 3 years ago and haven't had to touch it.

I've had the Pertronix in my car now for years and never had a problem. You might also want to check out the Crane XR1 system. Both fit under the cap and provide a stock look.

We've got two differant topics going here all under the heading of electronic ignition. The first one is Breakerless Ignition, which eliminates the mechanical points with an electronic device. The second one is a High Energy Ignition which applies more available voltage to the plugs.
It sounds like you want more spark which means more voltage. The problem is getting the HEI in a mechanical tach drive distributor. When GM put HEI in the Vettes they also went to an electronic tach. There are some HEI/Mech Tach distributors out there but $$$$$. I made my own using the base of an Accel dual point dist. mated to a '75 GM-HEI upper. Too complicated to go into here but it worked GREAT!! I was able to gap the plugs at 0.060 and never had a fowl out.
As a side note be sure your fouling problem is not carb related. Quadrajets are notorious for float bowl leaks into the intake manifold resulting in an over rich mixture.

You could consider an MSD corvette distributor with tach drive and hide the box in front of the radiator for good cooling. I believe the MSD fits underneath the shield too.

Yep...I wanted concealed but now I'm considering the MSD box and distributor and mounting the box on the passenger side firewall, inside of the car. Does anybody have a good idea of where to pass the wires through the firewall?

Jack71

Why inside the firewall? You must just want to keep it looking original under the hood, I respect that... how about tucked up inside a fender?

It just seems like a lot of work to get it inside the firewall and future access would be difficult.

Jack:

My brother has a 71 LT1 and just ran his thru the firewall to the passenger side. I was thinking this was a good idea. I do want to keep it original looking. He's gonna give me some of the GM tape which was used to wrap wiring to hide the MSD wires. I was wondering if anybody else had done this and where the put the box and ran the wires. Thanks.

I have my Crane HI 6 mounted inside and run the wires through the firewall. Not a bad job at all. You can't tell I have any type of box on mine. Not that I really cared I just thought it was a clean installation.

My only concern on locating the box on the passenger side inside the car is the possibility of a leak from the infamous heater core since they tend to dump the antifreeze on the floor when they go.

70454

I see your point. What about the RH radio support arm?

Gordonm

Mine is mounted to the right hand support tube. I made a couple of brackets to hold it there. The heater core would have to explode and go through the box to get mine wet.

:iagree: Although only with the Pertronix 2 have I had my experience.
