Rumblefish - Wouldn't this involve pulling the oil pump drive and moving it one tooth over? I always had better luck moving the plug wires one tower, either clockwise or counter-clockwise depending on the timing adjustment needed.
Carb selection help, please ?

That's interesting, thank you ocdart... So that my thick skull understands (bear with me here) if I'm sitting in the drivers seat and the distributor needs to be rotated counter-clockwise until the vacuum advance can hits the manifold (at around 1 o'clock position), I can simply move each wire one position clock-wise and then back the distributor away from the manifold and it'll run the same ???
Rob, I live about 25 miles NW of Hartford, and it takes me (depending on anxiety levels :happy6
about an hour and 15 minutes to get to Lebanon Valley... I've just got back into the dragstrip scene last year when I bought an SRT8 Charger, and got hooked again instantly.. My kids love it too, and I'm hoping that it helps to keep them a little safer on the roads if they have a place to "cut loose".....Best time so far with a basically stock SRT8 is 13.17@106.27, but didn't get the Duster ready in time to test her out...I have no clue what she'll run once I get the kinks out of her, but the guy who built the engine estimated 375 HP on paper (never on the dyno) It has a 3:91 rear that I upgraded from the stock 3:23's .. I'm thinking the Charger is still gonna whoop it, but I dunno ??? The fun thing will be a test and tune when I can let my 18 year old son run the Charger against me in the Duster !! It would be cool to meet up there sometime... I've always wanted to run at Englishtown too, so maybe you'll be able to "show me the ropes" there sometime ?? Kenny
Kenny, would love to show you the ropes, but I can't show you something i don't know about.
I have not yet raced @ E-town. Getting there is easy though. It takes me an hour to the city limits, approx. an hour to get through the city, time of day dependent, then about, more or less, an hour to E-town, again, time of day depedent.
Yes, it took 3 hours last time.
I'd love to go up to a different place just because it is different.

Yes. That is correct. The intermediate shaft would go one tooth over.
Plug wire towers could do the trick as well.

I don't know how you deal with that traffic down there !! Back in the 80's we did quite a bit of trucking out to Long Island with chemical trailers, and if we didn't leave super early it was a nightmare.. I can only imagine it worse these days ...
Lebanon is nothing special, kind of out in the middle of nowhere, but a little over an hour ride makes it fun, especially when we go up on Wednesday nights for test and tunes ..
Whattaya think about moving the plug wires, like ocdart mentioned?? Can it be THAT easy for me to NOT have to crush the vacuum hose into the manifold ??

Possibly. Yes. I allways moved the gear over myself. Thats why I said that. It free's up more moving room incase I need more advance, keeps the wires where they are so I don't have to remember that one over deal.
Hey, whatever works is all good.

so how do you do that ? All I remember from back in the day that I had a hardened distributor drive gear installed ... I can pull that out somehow and move it ?

just make sure your running 35 degrees total and make sure advance is fully in by 2k rpm,,, if vacuum operated, plug carb port set total to 35 degrees full advance in by 2 k, tighten dist, recheck timing, reinstall vac hose and you should have 53 degrees,,,,,,, total plus spark, if not get hex head that fits vacuum pot and turn screw til 53 degrees is acheived, dont mess with total ,your just setting spark advance at this point, never set initial, only used to start on a rebuilt perormance engine. its always total, no wont affect starting 1 bit. good for a few 10ths or more. look at my other replies in other forums on tuning, hey why is that distributor in the back? heh hope this helps

always use a degree wheel to centerline cam, this rules out cam troubles in the future
