They also have banjo rears. Nice and light!
1st visit to the track with the Dart today. Setup was sold to me as a 360 with flat top pistons, 509 purple cam, and Weiand aluminum intake backed up by a Streetfighter 727. It felt strong when I bought it but I wasn't expecting the 12.98 @ 104 it ran today. Cut a 1.9 60' that I couldn't improve with 2 other tries. Time to install the plate and work on that 60'.

Every time I dropped the clutch at 3 grand or more it would spin all the way through first with 2.10 sixty footers and 12.6 I decided to drop the clutch at about 1500 revs which resulted in the 1.85 sixty foot and 12.1. I had the tyres at 10 pounds should they be higher? Maybe I should buy some caltracs so I can get the sixty footers down I will run in the elevens without any more horsepower?

Never mind. Missed the part about stock stroke only. Sorry
Ha, I started this thread a while back, finally get to add to it. Now, I believe my combo should have gone faster than what it did - best was 12.20 @ 110.8 letting off before the stripe on a breakout pass. If I had run it out the back door, it probably would have gone a few ticks faster, maybe 12.1-12.0. Something was holding it back, this combo should have been easily into the 11s. The previous owner said it went a best of 11.97 but it had a 4.30 gear in it and couple different things. He said it usually went 12.0-12.2 which is where I was. I have not had the heads off so I don't really know any particulars without taking it apart. It is coming out for a stroker though so I am basically speaking in the future past tense, if that makes sense. Factory 340 block. 3.31" stroke, forged crank, stock rods. Pioneer balancer. Approximately 10.5:1 C.R. - 180 psi cranking compression pistons unknown. 810 casting W2 'race' heads (no rocker pedestals) - unported with 2.08" intake valves per the previous owner. These heads usually have 68-72 cc open chambers. Harland Sharp W2 rockers. Mopar .557 solid cam, lash set to .026"/.028" warm. Mopar distributor, no vacuum advance; 19-20 degrees initial, 35-36 degrees total, all in by 1,800 - 2,000 rpm. Firecore HEI-style cap and wires. Autolite plugs, can't recall the number, 8324 maybe? Edelbrock Victor W2 intake, no porting. Proform 750 double pumper. 75-85 jets, 4.5 power valve in primary only. Had various air bleeds in it, don't remember which were in it. Blue pump cams, 30cc diaphragms. Quick fuel air bell with K&N filter top. Carter 6270 mechanical fuel pump, regulated to 6.5 psi. 1/2" RobbMc tank pickup, 3/8" fuel lines to the pump/carb. TTi step 1 5/8" step headers intto 3" collectors. Full 3" exhaust with balance tube, Flowmaster 40 series mufflers. It's kinda loud. 904/999 trans w. T/A FMVB, no braking in first. Low gear set, B&M Pro Ratchet shifter. Hughes 10" street/strip converter, 3,800 stall. 4.10 gears, Mopar aluminum carrier, Auburn sure grip, Moser axles. 275/60/15 M/T drag radials set to 18 psi Caltracs with Calvert shocks front and rear. Offset springs. SSBC K/H type disc brakes in front, 10 x 2" rear drums, aluminum master cylinder with Line Lock. Battery in trunk. 3,060 lbs with a full tank of gas, 3,245 with me in it. No heater, radio etc. Lightweight bucket seats, full interior. Car idles at 1,000-1,100, dropped to about 700 (?) in gear. 10" inches of vacuum at idle. Shifted at 7,000 rpm, sometimes lower, sometimes higher. Car had very little torque off the line. It needed the 4.30 gears,. the 4.10 just didn't get it done. Again, best pass for me was 12.20 @ 110.8 with a slow 1.75 60 ft time.
