I was wondering if anyone has tried running a distributor with a crank trigger and box such as MSD. If so I would really appreciate any advice before I waiste the time or money.

Thanks for any help,
Bill

Unless you have built a super motor that will go to 7 to 9,000 RPM's you are wasting you time and money. Read some of the info about the subject and you will see what I am talking about.

I understand what you are saying. My issue is I want to have a very low profile Dist. for clearance of a modified tank and that was all I could come up with to gain that clearance. Any advice otherwise would be greatly appreciated. I was told by MSD that was the best thing to do. I trust what alot of you guys say and I am just looking for some ideas.

Thanks,
Bill

Hey Bill I'm looking to do the same thing so that I can bring down the tank over the distributor. Is this the one you got?
:click: MSD-83811


What box was needed to go with it?

By the way I'm guessing you cut the seat pan where it goes over the distributor, is that right?

THat'd be cool if you can make it work. It is a replacement for the LT1s optispark. I know you read this...


More performance for your LT1 ignition system.
Finally, all-out performance distributors to replace the OEM GM LT1 Optisparks--MSD's Pro-Billet LT1 distributors. They feature a precision-machined billet aluminum housing that fits in place of the factory piece, a new pickup assembly, a trick timing adjustment mechanism, and a new MSD distributor cap and rotor. The pickup is an advanced optical encoder that has proven to be very reliable and stable through extreme rpm and conditions. The rotor is bolted to a drive assembly that is indexed to the shaft, and is stabilized through the use of a large ball bearing assembly. The distributors use an adjustment screw to advance or retard the timing by up to 5 degrees.

Bill has this on his bike now and besides giving him room to extend his tank he said it runs much better too. I just need to know if this is the one he used or not. :roll:

That'd be great. Give you lots of room and I guess it really wouldn't matter where you mounted it. Just don't put where it can get wet like GM did with the C4 vettes. They put the optisparks down below/behind the water pump. They aren't cheap to replace and they hate getting water inside!!! Been there and done that...twice!!! I bet the MSD product is way better than the OEM gm stuff.

Keep us posted. I want to put in an MSD-6A with the rev limiter. Marv runs something like those on his bikes.

MSD BOX

Lamont,

I went with the MSD-6420. That may or may not be the choice of the Pros but it has really worked out well for me.

The dist I posted will not work for what you want. It does not have a mechanical advance. In other wise it is a race advancd locked out only.

I used this one before and the guy liked it a bunch. It is on a hot rod but what do we have anyway.

part number CRN-1000-1500




Add a Crane distributor to your powerhouse.
Crane has taken their years of automotive knowledge and applied them to these billet distributors. They feature a rugged billet 6061-T6 aluminum lower housing, a stainless steel photo chemically etched trigger disc that eliminates flex and corrosion, an aircraft-quality upper bearing for long life and precision alignment, a composite lower housing bearing that holds true alignment, and solid brass cap terminals to ensure maximum current conductivity. They are also fully urethane-sealed against dirt, oil, and moisture, and don't have weights or springs to wear out or break. As if this weren't enough, the distributors have a magnetic trigger that works with most Crane ignitions and many others. Add to that nine electronically programmed "mechanical" advance curves and three electronically programmed "vacuum" advance curves, plus the "zero" position that provides an advance lock-out for crank trigger ignitions. A built-in precision M-A-P sensor, a race-proven optical trigger for precise firing and reliability, and accuracy to +/- .5 degrees at all rpm levels are all added bonuses from Crane. These features make for spectacular, maintenance-free distributors that are at home in street, race, marine, and off-road applications.

Adrian...Two years ago I ordered one of the Crane units you have posted.
I sent it back because of two issues. First, the most aggressive advance curve had it all in at 2500 rpm and I didn't think that was aggressive enough. Second, the ignition module was very big (8"+ long) and I couldn't think of a goood place to mount it.
What do you think about the advance thing and where did you mount the module?...Joe

I put this one on a 32 street rod high boy and we put the Module under the dash. I never looked at it very close because we had a bunch of room.
Unlike Lamont I don't need any extra room on my bike. All I feel we need is the advance by Crane, good wires, with cap, rotor and maybe a MSD coil.

Adrian...Are you saying the Crane fully electronic unit will work without a control module? I don't know what these modules do other than to have a rev limiter and produce multiple sparking. Frankly I don't need either of these features...Joe

No Joe, it does require a module but in a car you have all kinds of room that we don't have on a Boss.

Adrian..that module is 8 1/2" long and HEAVY. Suppose we could find a place to mount the module the other thing is that the most aggressive advance curve it offers is all in at 2500 rpm. That means you won't be at full advance on the highway till over 80 mph with a two speed. What do you think?...Joe
