duraspark 2 on a crossflow

[Anonymous]

I am a little confused and i hope someone can clear this up for me. Will a duraspark 2 dizzy fit a carby crossflow? I know the block must be bored to accept the larger shaft of the d2 but I thought Jack said the cap would not clear the intake. Is this just on the fuelie crossflows? Will it clear a carby intake?

I'd personally look at trying to find a small body HEI distrubtor off a US Chrysler 225, or Ford 2.8 Mustang II (pre Duraspark). These are small enough to fit.

It's clear that you Americans need a good resreve of parts, and unless you can get a stock of consumables from the Aussie importers on this forum, you may be better looking into an adaption. Looking at the cost, Spyke, I'd buy two Aussie distributors with new caps, rotors and bushing.

Yes, but then you need to do two things.

One, grind the block to clear the distrubutor body. There is over 400 thou
of extra meat on the distributor side. It's pretty tight getting enough 'arm room'.

Two, find another intake manifold, as theres no way a cross-flow intake will fit. There is very little room around these Aussie disributor, and none with a Duraspark II

:idea: Unless you do this:-

Your only other option is to put a 1.5" penolic plate gasket on the intake manifold with really long bolts, then shove a 10.0" steel extension to the distrubtor drive and body, placing it up wards above the intake manifold, and shove it out the bonnet.

Just being smart. This is incidently, the only way a duraspark will fit a cross-flow head on a 200 US engine. Space the manifold out.You'd then have to place a 8.5" extension on it to fit the distributor body above the intkae manifold.

Been doing lots of thinking and checking with my little 200 cube 66 Falcon engine. There is just enough space for the distributor to poke through number 1 and 2 inlet tracts (edited from 2 and 3 inlet tracts. My bad...). Bit of an heroic mod!

Beware. This places the electonic distrubtor right beside a fuel source....the carby :fume: :splat:. Don't do it, you'll want to sue my a$$ off it it went on fire...

hrmmm
X, have you told this idea to Jack yet?

The Bosch unit is superior.

You could cripple the motor to fit a Duraspark, but why? The Bosch has no need for external control boxes, is available rebuilt and recurved for about $290 outright (with new cap, rotor and original coil), will behave up to 6000+ RPM in stock form, and has been proven for reliability.

Only spare needed is a spare module at about AUD$75 genuine, new.

Cheers, Adam.

I have no experience with the Duraspark, but can confirm the abilities of the Bosch unit. They are a reliable unit for sure, Addo wont lead you astray

Actually Im talking about a straight crossflow and not a us200/crossflow head hybread. Not sure if this matters?

 

[addo]

No, it doesn't matter. The hybrid would be slightly more cramped, but XE's comments still stand.

The US distributors have a larger diameter shaft than the Oz engines. The duraspark will only fit if you either:

A. Turn the DII distributor shaft down to fit (preferred), or
B. Ream the lower shaft opening on the block.

The DII is taller than the Oz dizzys and is harder to service because of the intake manifold, but not impossible.

Other than that, the DII will work fine on an Oz 250.
