    Cecil County 10-19-24

    I last went 9-13-24. Here's the thread- Cecil County 9-13-24 A bunch of stuff on there. I'm trying to simplify now, lol. This time I got 4 runs. The D.A. is written on the slips. I made all runs the same except for this: I had my pin-on glass hood "floating" at the back.. I.E. longer...

    Cecil County 9-13-24

    I'm going to try out a few things tonight. Anyone else going? These two threads have the info: How To Measure Fuel Volume. Advancing Cam Question But basically, I'm going to: -See if the cam advance affects it. (From straight up 108, to 104.) -Check trap RPM for the effect of the 2" taller...

    How To Measure Fuel Volume.

    I have about 15 runs on my street/strip Duster with maybe 350-380. HP, 3200 (actual) convertor, 727, 4.30 gears, and when I last ran it, 26" tires (It has 28's on it for the next trip.) Only about half the runs were any good because of shifter problems. I shift it at 6k. I haven't gotten a good...

    LED vs Incandescant

    I haven't raced competitively since christmas trees had incandescent bulbs. I used to be able to see the light coming on, being on, and going out, as lots of racers did. Always foot braked, .500 tree. One car ran mid 14's, the other 11.60's. This was in the 80's and 90's. Since then, I have...

    More Seat Belt Baloney

    My car doesn't run below 11.50. This excerpt from the 2023 rule book says that because I don't require a SFI 2" etc. harness (11.49 and quicker), I can run an expired SFI without an issue. Mine is dated 2019. I don't have a roll bar, and only use the lap belt portion of the SFI. When I went...

    Taking It To The Track

    I've linked a few posts about my Duster clone. I started working on it in 2008. I got it running last year, and worked the bugs out. I maybe put about 2-300 miles on it. Tuesday, May 16th, I'm going to Atco to see how it runs. A "Test 'n Tune" night. Anyone else going? Drove My “New” Duster...

    Vent Rear of the Hood

    I have a lift-off glass hood. I'm thinking of venting under hood heat by raising the back of the hood a bit. Has anyone tested this? There's no cowl seal, so maybe it won't matter much? I know they used to look for that seal on Stock Eliminator cars. I guess "forgetting" to install it helped.

    TROG No Safety

    How do these guys get to run with no roll bars, non-Snell helmets, and probably a piece of rope for a seatbelt? I know they don't run NHRA tracks, but c'mon! The Race of Gentlemen: Vintage Drag Racing Returns to the Runway!

    Drag Strips and Antifreeze

    Dragstrips say no antifreeze. Then they let a hundred street cars go down the track. I know antifreeze is hard to clean up. Do they really mean that they don't want antifreeze, but they know they can't enforce it because no one will show up?

    Car Weight

    I weighed my new project at the county dump today. (I thought they might try to keep it, lol.) 2760# without me (I'm 200), 1/4 tank of gas. -74 Dart Sport cloned into 71-71 Duster. -Fiberglass hood (lift-off), fenders, and bumpers. -Aluminum bumper brackets. -72 doors. (no crash beam)...

    Ballpark Gear Ratio

    My Duster clone is roughly 3000# w/ me. I haven't had it on a scale yet. 'Glass bumpers alum bumper brackets, glass hood and fenders. Minimal interior (2 Corbeau buckets), no heater, Weld Pro Stars. It has a 360 w/ ported 915's, 770 vac sec carb, Torker II intake, 292 purple cam, 11.25:1...

    Coolant- What To Use?

    The last time I raced regularly, we used water, and drained it in the winter. I know the tracks don't like antifreeze, though a zillion street cars go down the track. The car has brass freeze plugs. I kinda remember reading about using some kind of additive? Maybe to prevent corrosion? In...

    Starting Shift Point

    My 360 has a 750 vacuum Holley, Torker II, 11.25:1, ported 915 heads w/ 2.02 intakes, 292-.508 purple cam, 1 3/4 headers, stock rods and crank. I bought it with all of this and have disassembled it to verify everything. I can’t speak to the quality of the port work. I don’t know who did it, and...

    Battery in Trunk Wiring That Exceeds NHRA Requirements

    Please PM me regarding this. I was posting on another thread regarding this subject, and I am now completely confused. Specifically, the subject is to put a battery in the trunk, wire in a cut off switch and do it in a way where there’s no hot wires going to the front of the car other than...

    Front Suspension Travel

    I know Calvert recommends at least 5". How is it measured? Is it total travel, from completely collapsed to fully extended? Or is it from ride height to fully extended? It seems that if they mean overall travel, the effectiveness would depend on how low (or high) the torsion bars are set...

    Street/Mostly Strip Front Suspension

    I've cloned my 74 Dart Sport into a 70-71 Duster. As the title implies, it will be street driven, but not much. It'll get used at the track. It should weigh about 3000 lbs. w/ driver. It has a small block, automatic, glass hood, fenders, and bumpers. It has 6 cyl. torsion bars. (About .854"...

    Drag Race Rear Shock

    I've cloned my 74 Dart Sport into a 70-71 Duster. I don't know weights yet, car's not done. It should be decent from to rear. It has a glass hood, fenders, and bumpers with aluminum brackets (front and rear). The battery will be in the passenger side of the trunk. It's a 360 (est. 400 hp)...

    SFI 3.2A/1 Jacket

    Are these jackets dated? A friend has one from the early 90's I can borrow, but he has to find it. I told him I'd try to find out if it's any good now before he looks for it. Is SFI 3.2A/1 even the same spec as will be on that old jacket? I mean, have they changed the spec?

    Air and E.T.'s

    This is well known to most who race, but I thought I'd bring it up anyway. I read a lot of posts about e.t. improvements after changing the combo. As most do, only one modification at time can be evaluated. Here's what I'd like to point out (to those who may not have considered it)...

    Time To Buy A Helmet

    I haven't bought a helmet since the 80's. I was just poking around the web and found one for $27.95! DOT approved, not SNELL. NHRA requires SNELL, don't they? I want to get a good one, but I don't want to spend a bunch. Same old story. I don't race much and I don't need one for anything...
