Can't thank you guys enough.  I now have enough info to be dangerous!!  hahaha..

Thanks again,

I just put a MSD 8383 direct drop in distributor into my '56 F250 stock 272 . I need to do a bit of tweaking on the timing curve etc, but it started first kick. Seems to be a good unit. That is with a single Edelbrock 94 carb. to get away from the Load-o-matic that came stock. Be aware that to do said "tweaking" you have to take the distributor cap off and change out springs which is kid of a pain considering where the distro sits at the back of the engine. If you want to set it up accurately you will need a tach that goes up to 4000 RPM to check various points along the advance curve. The Ford manual has a little chart showing the advance at various RPMs (note this is distributor RPM, not engine RPM) and the Distributor comes with a set of advance curves based on different spring configurations.

Other things of note...The 8383 is a bit taller than the stock so plug wire length may have to be adjusted, and the connections on the top of the MSD are like a spark plug, not well connections like the stock unit. LMC trucks has the rubber grommets to route the wires behind the block like stock. The holes in the grommets are small so you probably want to use 6.5 or 7 mm wires, not 8's like I did.

I hear you Tim, whether I realise it or not, I probably use the term also, the stuff just grows on you reading these post, you become foreign whether you are there or not!

Guys thanks for the input.

Well, the more I learn, the less I know.... lolol..

Now I am thinking about the 57' (or up) Distributor with the Petronix mod.  A few questions:

Where are you guys buying the distributors? (new, ebay, ect??)

Thanks,

Ryan

I like that term, it's easy to spell. lol

The MSD 6AL sure makes a differance when you start a cold engine with 13.5:1 and a good shot of 110 race fuel.

I think you could be wasting money on the MSD [6AL] for your motor. I read time and time again guys that "race on the weekend" talking about changing to MSD and then find that it makes no difference.. I think they just like the look of the box. Now someone can correct me here but Im sure the multi spark cuts out at 3000rpm anyway. DOnt get me wrong its a good ignition its CDI I believe [good for real high compression] but, I wouldnt go past the 57 onwards dizzy with a pertronix  or Accel kit. try the ignitor 3 setup its multi spark all the way through the rev range and a damn sight cheaper than MSD. re-curve your dizzy and your away.

Boy Tim, you have been reading too many Aussie post, they got you calling the distributor a dizzy now!

I like the stock '57-up dizzy with the Petronix. I've been running Petronix in all my early cars since around '95 and had nothing but good luck.  I even run the stock style dizzy in my race truck with a petronix to trigger an MSD 6AL.  Hard to beat and the price is easy.
