Title: Tunnel ram distributor
Post by: coors909 on December 20, 2015, 01:03:38 PM
I have a tunnel ram that I'm going to be installing on my BBC from my past experience my HEI didn't fit. So will a MSD ready to run or MSD certified distributor work?  Also what MSD wires work with these?

So I need a box with this distributer right?  Will the marine MSD or non marine one work?  Also does it need a crank trigger?

It does need a crank trigger unfortunately. Doesn't matter what box.

Well, honestly if you are worried about the water run the blue box. I've always ran the digital boxes and have been fine.

I would run the non crank trigger one because it's an extra 300 bucks to get the trigger from MSD. Idk what motor is on but for a lake hot rod or stock application I still say you won't need it.
If it was a full blow race boat, then I would run the crank trigger.

Ok it's just a BBC with a cam, tunnel ram and big carb. I'm going to build it up next year but only roller rockers and some nice pistons and some other little things. Maybe like 500 hp or so. Trying to keep it reliable

If you want to spend the extra money, by all means go with the trigger. But for now I would go with the non trigger one.

Sorry to keep asking questions I just really want to get the best setup. Will the crank trigger work with a 4 point motor mount set up?   Will I be able to adjust it while it's in the boat?

I've been running a Pertronix Flame-Thrower III ready to run distributor in my BBC for several years now without any problems.  I'm running it with an MSD coil and Wires also with no problems (and I'm pretty sure the distributor doesn't know that the coil and wires aren't the same brand  ;) ). 

The Flame-Thrower III has a built in rev limiter, multiple sparks, billet housing (yada, yada, yada)...

Just another choice if you're looking for options.

I like the MSD universal sets because I prefer to taylor my wires to fit.  On the boat I used the 90 degree boots at the spark plugs and ran the wires under the header to the rear and up and didn't require the heat socks.  On my daughters truck I used the straight boots and had to use 4 socks where the boot rested on the tubes.

Ok good to know thank you. I think I will go with 90 degree one. I'll post everything after I buy it.

This is often referred to as "Corvette style" just for reference.

Do you remember the Jacobs Ignition wires with the ceramic ends?

Super trick.

Sent from my iPhone using SoCal Jet Boats

Think of it this way.

The conventional distributor is driven from the camshaft which is driven by a chain and sprockets, belt and pulleys or gears, and then ultimately to another worm gear. The opportunity for inaccuracies are pretty strong.

The crank trigger is signaled right off the crank. No potential for slop and way fewer moving parts. Don't have to worry about distorting components either (cam twist etc.)

An even larger advantage is that you can literally see the timing changes in increments of a half of a degree, even less if you really want to split hairs.

Ok makes sense, so with that setup do you lose mechanical advance and just run locked out timing?

An ignition controller can be used to control the timing. You can get stupid exotic with ignition systems these days.

You can do it with a manual dash mounted control, or with an elaborate ecu of sorts.

Honestly all you would need is a start retard module in most cases.
