Do the Interceptor boat motor Mallory single point distributors fit the regular Y-Blocks? If so I have one on the shelf. I would think with the Mallory tolerance's it would be a good choice to convert to electronics. Any comments? Chuck in NH

Chuck, Watch the rotation. Gear drive, should mean the distributor gear's wrong.

The one I have out is from a normal right rotation engine. I will have one from the other side. I would assume that changing the gear would fix it? Chuck

My take on the reverse rotation engines is this. The cam is gear driven, which makes it rotate opposite crank rotation. So if the engine crank is running "backwards", the cam is still running "forward", so distributor rotation should be the same as a chain driven cam in a "normal" rotation engine. I have never checked a reverse marine engine, so this is only a guess. If the Mallory distributor has centrifugal advance, you should be able to hold the shaft and move the rotor counter clockwise a little against the advance springs. This would be for a counter clockwise distributor as found in non-marine engines. If the rotor moves clockwise in relation to the shaft, it is for clockwise rotation and would not advance in a regular engine. If it moves neither direction, it is a fixed timing distributor, which may happen in an engine operated at a fixed rpm, as could be the case of a large dual engine boat. John

Chuck, I pulled mine tonite, John's correct. The gear is the same, but the distributor points are reversed from my factory unit. Not sure why they did that. The Cam and distributor rotation is the same as stock. Mine has no advance, it's locked. Even if you find an older Mallory, Ithink you be better of with a '57 up factory unit, recurved and converted. I don't like the Mallory advance setup, they tend to wear out quickly and the timing becomes erratic. MSD is making a complete ready to run electronic distributor. I like their stuff, it works well, looks good and doesn't seem to have quality problems.

the MSD rocks - last summer I drove from chicago to detriot - 75 mph all the way, 20 mpg, car never skipped a beat

Band New Mallory distributors are still available for the Y Block, both Vacuum & mechanical advance. I got one from Summit Racing, it is not in their catalog, but you can special order one. That was a couple of years ago, so I don't remember what it cost. I bought the mechanical advance one, works great for my 292, my 56 Fairlane is not a go fast machine, just for normal driving around town with an occasional longer trip, I did drive it to Charlotte, NC from Richmond, VA and back without it missing a beat. I had a supercharged 91 Mustang GT 5.0 that I was going to put in it, but changed my mind, nothing sounds like a Y Block with glass packs. I sold the 5.0 and spent the money on the car. Nothing like a Y block. I really like the website's spell check feature, I can't type for beans!!!

How much movement is expected for the mechanical advance? The Mallory I have moves maybe a 1/4" or less but it does move. That is counter clockwise if you hold the shaft. seems it will work? I would think the closer tolerance in the Mallory unit would make it great for the electronic conversions. Chuck

Chuck: 1/4" movement would be a short advance curve, would probably be used with more initial timing than stock. CCW is correct. Are the points mounted backwards like Frank's unit? John

John, The points are mounted with the stricker facing counter clockwise. I no longer have a stock distributor to look at but looking down they look reversed to me. As I recall in normal rotation the distributor cam comes from behind the stricker in reference to the points. This one comes from the front. I'm not sure if it would really make any difference. I do want to pull the plate and see what the advance really looks like. Chuck

Chuck: Sounds like your points are "backwards" too. I doubt if it makes a difference, many dual point setups have one set one way and one the other, and they are for high performance use. Should we move this discussion to the technical forum? John

I guess your right. I'll check the advance stuff tomorrow and post it on the tech forum. Chuck
