Thanks mate. Will check these things. I've left all the original electronic wiring there so wouldnt be hard to put a new dizzy and original dstyle ECU back in.

Yeah, I think I'll go back and do timing and carby and see how it goes.

Nah, vacuum advance is blocked off.

Yeah, when the car is hot it happens thru the mid rev range. Also noticed that when I jump on the throttle ant high revs it wants to die (sounds like a fuel issue) Have changed all the leads on it. MSD Blaster Coil is near new. There's no ballast resistor on this set up.

Correct, there's no Ballast Resistor on this.

I'm running Quickfuel 750 Double Pumper on it. Ignition timing is at 14 (I think?) Yeah I've got an old MP distributor on it.

It's been there for ages. Its usually once the car is hot and above 1,500rpm on the throttle. Doesn't do it at low speed or cruise.

Hi All, Hope everyone is staying safe. Just want to ask advice with misfire/ignition on my 383. It's misfiring slightly above 2000rpm and damn annoying. It has stock Mopar electronic dizzy and MSD Streefire Ignition module. Have change plugs, leads and still hasnt fixed it. Any ideas on where I...

I'm quite sure there's 5 leaf's in these springs.

Need some help and advice on rear leaf springs on my '73 Duster. Unfortunately I made the mistake of putting Mopar P3412003 (3200lbs) leaf springs in it (to replace the old screwed springs) and the car is jacked up real high and want it sitting way lower. Anyone have advice on what I should...

Oh dear! Yeah, they're good for storing nuts and bolts.

My pleasure. I have recently dropped the car about 2" on the rear and the 275's did rub on the really thick lip on the guard but nothing a die grinder didn't fix. Now I've got plenty of room under there.

Yep, this is in stock wheel well. Sorry for the late reply.

I've got a virgin bore 440 bottom end at home. Im better off just building a new 440 bottom end I reckon.

Piston to Valve clearance might be an issue. Ive got Mopar Perf Purple 484 cam in the Duster and do want to put a bigger cam in it but understand I need to sort out compression first and the like. Get the block decked or new pistons with relief to push compression up. I'd love to get compression...

Absolutely! Want to make sure everything is sorted before I do anything else. Pistons are down the bores around 70-80 thou, flat tops and 84cc heads milled down 50 thou. So I reckon it would be roughly around that.

Still haven't had the chance to get the Duster back out. Bloody house reno's have gotten in the way and working on the Polara. Have sorted dizzy problem and will have no issue getting timing into it now and have re-set the rear as well. Hopefully when I get the chance to get it back out there I...

My 73 Duster (383) comes in a 3600 with full fuel. Damn heavy old girl..

Yeah might need to get some more comp and cam into my donk one day.

What an awesome time! I've got Schumachers on my 383 Duster and best investment I made. Just so easy in the engine bay. I wish mine could run those numbers.

Thanks for the advice. Yeah, its got MSD Streetfire. So far its worked really well. I'm going to sort that timing out first and get it back on dyno for a good tune and check the plugs and I'll take the old girl out again and see how she goes..

This is all I have..

Yeah, I think I might have to try a few different things next time I go out.

I'd be stoked if it runs mid 12's. That's what I'm hoping before I do anything else on it. I've also got NX Hitman set up if I get the itch to go faster but want to get it sorted and run nice and clean.

Yeah, the rear end is really stiff and I need to get to the track and muck around with it more. It was spinning the boots. It was my fault as I was doing mega burnouts with the Drag Radials. Yeah, I'll fix the timing issue first as well.

Yeah, I have to sort this out. It's the actual dizzy cap clip that hits the damn head. Running 12 or 14 initial I think? it was a while ago I had it on the dyno.

Hey Guys, Just for your tech heads and racers out there. What ET should my Duster be running? And any advice on how to pull more power? Here's some specs of the basic combo.. Weight: 3600 pounds (with my fat *** in it) 383 Big Block - stock crank and rods - 30 thou over 9.2:1 comp (flat...

Holy shite! That's awesome!

Man, I'm frustrated then and something wrong with the set up in my Duster.

My Duster comes in at 3600. Damn heavy. Quickest I've run is 13.10 @ 106 but need to get more timing into it and for it to hook up properly. It's spinning the 28" ET Drag Radials.
