Header comparison and Duraspark II

I was wondering what the pros and cons of the different dual outlet headers for the 200 inline six are. I was also wondering if i should be looking for a single or dual vacuum advance distributor. Thanks.
 
as far is performance goes, no real difference in headers. Quality is the only big issue, and from what I've seen fordsixparts.com has the best. I had a set of cliffords that I never installed, and compared to the Pacemakers from FSPP, they looked like crap.

Got single vacuum advance for DS2 unless you are really worried about squeezing .1MPG out and 1ppm CO emission increase. To me, it doesn't outweigh the additional tuning it requires.

I would go with the dual outlet header. Get the best from mike at FSPP.
www.fordsixparts.com The primary pipe length is more equal in the dual outlet header, wether it be pacemaker or hooker.
For the best sound run duals with a H pipe or better yet an x pipe. the muffler choice is yours. flowmasters are louder, borla sounds great & dynomax would be even quieter. William
 
thanks. I'm going to get the dual out pacemaker from fordsixparts.com. As far as the DSII goes, is there anywhere to get the wiring other than a junkyard? I prefer to use new parts whenever possible.
 
you'll be able to get everything new at our local parts store
tell 'em you want the Distributor, cap, rotor, and control module (if you don't want to use the GM module) from a '79 Fairmont with a 200 in it
 
Clifford is good quality but i think there fabricator was smokeing something when he made mine because there is only a quarter of an inch between the header and starter. I hope that starter doesnt go out cause thats a good days job changing it, rather than 30 mins. I have a 67 ford falcon i dont know about the stangs.

I've got another question related to the Duraspark II conversion. I know that the load-o-matic distributor will not function properly with a carburetor that doesn't have the spark control valve. My question is will the stock carburetor (autolite i believe) work with the duraspark II? I ask because my grandfather always tells me to only make one change at a time, that way it it doesn't work you have a good idea of what's causing your problem, so I'd prefer to switch the distributor and carburetor at different times.
 
Though the two work in conjunction together, I currently have the 1100 carb with the spark control valve, and the load o matic distributor. Ive got everything ready to go for the Duraspark II conversion, but work and weather havent permitted me to do it yet. I too will leave the 1100 till I can upgrade the carb.
My point being, is my vacuum is disconnected from the load o matic dizzy, and the previous owner had plugged up the spark control valve on the carb, so there's nothing connected between the two. I dont have any problems with the car starting, running, or acceleration. Hope to have a lot better idling, etc with the DII.
Edit: the idling isnt that bad either, didnt want to mislead on that part. All of this may go totally against what should be happening with my current set up, but it really could run a lot worse.

THe question is, will your DSII have too much advance under load. (the SCV will give vacuum where all other carbs would not...under load).

The load-o-matic operates on a lower vacuum than the DSII, so you will likely be fine in all but the highest uphill load under full throttle; even then maybe.

I ran that way for about a month while awaiting my 2-V carb adaptor. No problems.

Your grandfather is a wise man...one thing at a time, get it right, then the next...

Good luck. Also, I've posted a link to my DSII conversion...its a "how-to" layout. Here's the link: http://members.cox.net/joetrojan/

Good luck,

I would simply hook the DS2 to manifold vacuum and tune it accordingly. Many engines are run successfully with no advance whatsoever. Have you ever had to set the timing on your lawnmower? I own several tractors that have fixed ignition timing and they run just fine, albeit in a rather narrow RPM range. Your engine will perform better with a proper advance, however.
