My 383 / 727 / 8.25 (4.10's) Duster went 13.10 @ 106mph with 1.97 60ft times on 275/60/15 ET Radials in street trim thru full exhaust. Gotta sort out the rear and get those 60ft times down before I put a 100 shot of gas thru it..

Got hold of my SS springs, Comp Engineering 90/10 front shocks and new Gabriel rear shocks. Looking forward to getting these in and getting back out on the tracks and doing some tuning to the Duster and my driving technique. Will also give the front end an alignment as well.

The heads already have hardened valve seats and yeah it would be good tobhave more comp. Im gonna work on rear end set up, launch and driving it as well. Ive got a 440 block at home as well.. mmmm...

Have to look at a few things.

Ive purchased a set of new SS springs which will assist in traction. We have 98 octane fuel whicb is what I use.

Honestly, initial timing is around 14 degrees and total timing is around 32 if I'm not mistaken.

I think it was around 5,700 or so.

Yeah, it's the first time I'm run the old girl. I suppose I should work on car set up and driving the car properly.

Hi All, Have another thread in here but it's an offshoot so thought I would start a new thread in the relevant section and ask advice. Thanks to a few Members who answered some queries in another thread. Just want to get some advice in regards to the combo in my '73 Duster. Took the Duster...
