Difference in distributors?
Current setup is a HEI distributor. Chevy 454. It is a no brand name model. I rebuilt it, new cap. THe truck runs fine, no issues.
WELL, today my boss came and handed me a new Mallory 85 distributor. http://www.summitracing.com/parts/MAA-8548201/All/ I heard mallory makes a good product. Do you recommend replacing my current no name brand with this unit. It just feels bigger/heavier then the one i have now. It also has some kinda vacuum advance control inside. I dont really know much about these distributors. I would hate to replace it and run ito issues ya know. ahah. Any advice.

Re: Difference in distributors?
I think you should just send the Mallory to me.
![]() I would say, if the boss is giving you stuff, throw it on, keep your old part as a spare. Keep the boss happy by seeing that you are using the stuff he gives you... you may keep getting free stuff that way. ![]() Again, my shipping address is... LOL

My other concern is the vacuum advance. I dont know how to use that thing, it seems adjustable. lol. The coil looks so much bigger and nicer. Malory dist. with a msd ignitor on it. IM assuming that link for summit is WITHOUT the ignitor.

Re: Difference in distributors?
Does the HEI in your 454 have a vacuum advance? If so then the Mallory should be fine. It will put out a hotter spark... I'd use it in a heartbeat.
Post up a pic of what the vacuum advance looks like. Is the coil actually bigger? Or just the cover that goes over it? Gary

Yes it has vacuum advance on the dist. i have now. I talked to my boss and he said the dist. is set up for a high horsepower engine and he wouldnt recommend it on mine. His engine was 600+ horsepower without the nose. Just the overall size of this thing feels bigger. ahaha I havent held my old one in a while, but i just dont remember it being so awesome feeling. lol.

Re: Difference in distributors?
That thing is sweet... It will work great even in a stock motor if you ask me. I wouldn't hesitate using it. The MSD coil might be a tad larger, because it has more windings in the primary. Hence it will feel heavier too.
Good unit... it's from CNC'd cast T-6 aluminum on the top,and billet aluminum on the shaft. Probably also why it feels hefty. Toss a new set of 8mm Mallory or MSD wires in with it and it will be sweet. The vacuum advance looks pretty straight forward. I would ask your boss where he had it set to advance, and see if he can help you adjust it. Here is the instruction sheet for it... http://static.summitracing.com/globa...aa-8548201.pdf Gary

Re: Difference in distributors?
He said he added stuff to the internals. Said he paid 500 bucks for the whole setup.. Summit says its 135, but i think its bare, im not sure.

So swapping dist. Can i just unbolt mine, mark where the rotor is and install this new one with the rotor in the exact same location and have no issues?

Re: Difference in distributors?
I would think so... since you have an HEI already... it should have the connector and eveything already there.
![]() Do you have the dust cover for the coil? Gary

Re: Difference in distributors?

Re: Difference in distributors?
Yes. Im reading it now. THis just gives me an excuse to get back in the garage. Ever since i started building my truck i go through phases. Where all i want to do is wiring, then all i want to do is motor, then all i want to do is paint... Well, right now i need to be in paint phase, but all i want to do is screw with motor work. So i cant seem to finish the truck .LOL.

Re: Difference in distributors?
Bump your engine over to bring #1 up to fire before you pull the old distributor. It makes re-installation so much easier; at least for me it does.

It should be blowing your finger out of the spark plug hole at the #1 Driver's side. Nice looking dizzy. If it performs as good as it looks you should be golden!
