Dart270.

I think there is a lot of umph that was lost with a 4000 rpm shift, and getting into third gear didn’t help a bit either. By what you guys say, high fives are possible and not detrimental to the engine, than I had a lot of revs left in second at 660 feet.

I can’t wait to head back to the track to add 1000 rpm or a bit more to the shift point.

I won’t be swapping out the third member for a shorter gear.

Yes, 5000 RPM should be totally safe.

All & all a great weekend with grandson & granddaughter there along with my son Alan & didn't need Mater to get back home. Those people did a great job making the tow truch look just like the real thing nice meeting you guys , see you on Sept 11 @ Darlings show , Ron

Sounds like a great outing. 8.11 is movin'. I love the 'Mater truck too!

A little off topic, but…

The following day, Sunday, I took the LeBaron in the other direction, north, a few hours to a car show in potato country. Nice little show held at a Ford dealership with just under a hundred show cars, 15 motorcycles, a hand full of automotive atrocities, and perhaps ten nicely restored antique tractors. Always, tractors at car shows in this end of the state, and always done up real nice.

About an hour before the show was to end, I looked down the through the show, and there sat an additional, not so nice looking, assortment of antique farm tractors lined four abreast and five deep, all jammed in, in formation. Apparently, the local antique tractor club, dropped in after a weekend of pulling, for a look at our stuff.

All that came to my sick twisted mind, was that seen in Cars, where the tractors invaded town, and where is Mader…

On the way out of the show, in a slow moving parade, several of the great snorting beasts gave the “auto teeter-totter a whorl. It was all quit weird in a fun way.

Me quoting me:
Went back to Winterport Dragway today for a car show & time trial. As always when the Gassers, lawnmowers, snowmobiles, and motor cycles are there it is chaotic, and long lane lines… Something I don’t deal with very well.

I did make one time run, with the plan to manually shift at 5000 rpm, an arbitrary point, but a plan. My car doesn’t wake up until into the 4000 rpm range, so letting the old Torqueflite shift automatically at 4000 rpm is a waste of a run.

For some reason I neglected to pull the stick all the way back into first gear, and left the line in second. While watching the tachometer run up in anticipation of a nice 5000 rpm shift, the damn thing hits second right at 4000 rpm…*&%f# it all… Well that run sucked almost as bad as this springs two runs.

My reaction sucked at a comatose 1.134 sec.
60 foot at 2.408 sec. (unaffected by early 1-2 shift)
330 ft at 6.923 sec. (most likely slowed by premature 1-2 shift)
1/8th at 64.56 mph
1/8th time; 10.673 sec.

I don’t quite understand these numbers. Is my reaction time inclusive of the total elapsed time? So removing the reaction time from total time yields what the car covered the 1/8 in?

I need to install an O2 sensor for better carburetor tuning, and find a dyno to figure optimal shift points.

RT(reaction time) is the time it takes for your car to move out of the stage beams once the light goes green. So in your case the light went green and it took you 1.134 sec to move.
The ET(elapsed time) timer doesn't start until your car moves out of the stage beams.
RT doesn't effect ET. Sorry, probably not what you wanted to hear.

Got it.

So two cars with same ETs, the first guy to cross the start line wins.

The guy in the other lane had a late model Mustang GT, his reaction time was 1.236 sec, and he was one second faster at 78.67 mph.

The car is still a pig at a converted ¼ time of 16.63 sec… I think it should be running in to the 15’s.

I’m going to degree the cam later this fall once the car is put away for the winter, and see if there is a problem with it.

A summary of past few years’ above previous postings chronicling my less than stellar racing career: LOL


2011, o2 sensor did get installed late in season, it did help tuning the old Holley 390, and by early fall of 2012 I managed to sort out most of the jetting & engine tune issues.

Winter of 2011 I did degree the cam, found a healthy lift and big overlap.

I discovered this engine easily cranks to 6000 + rpm. Having found and talked with the guy that built this car he dragged it for four years c. mid nineties, at Englishtown, NJ, winning his bracket several years in a row, and when asked what he used for a red line stated; I got the biggest cam Clifford had, shifted at 6300, and blew up five engines before figured out how to build one that would stay together…

Fast forward to fall 2012, Winterport Dragway’s final hoorah with car show, flag start Gass’ahs, assorted other race cars, and atrocities will be held in two weeks; I plan on making a few 1/8th mile runs with the Dart that day.

Winterport is aptly named as it was 28 degrees when I pulled up anchor this frosty morning to motor down river to Winterport Dragway. By the way, summer was nowhere to be seen today, as temperature slowly topped out in the upper forties with just a bit too much breeze blowing for comfortable hanging-out at a car show… The red hotdogs were good though.

I did make one run down the 1/8 mile after staged in line for an hour while the track crew cleaned up a grenaded Chevy transmission just over the finish line… I guess transmission oil ain’t easily sopped up from cold pavement, and I don’t sit in lines very well either listening to the symphonic racket of big blocks blatting from all directions…
Finally the log jam broke, flag start Gassah Days was back to burning rubber, and braking beams. I made one run managing to get used to a helmet, and not being able to hear my engine over the cut-out pipes in the other lane; this was something that rather disorientated me last time I made a few runs a season or two ago.

This time I managed to successfully row through the gear for a 6000 rpm shift, and never did slide into third gear before 660 foot finish line; she still had more revs to give.
Results of single 2012 1/8th mile run:

Reaction; a comatose 1.229 sec.
60 foot @ 2.336 sec.
330 ft. @ 6.736 sec.
1/8th at 67.95 mph.
1/8th time 10.352 sec.


So long story short comparing previous outing with today’s
60’ shaved 0.072 seconds
330’ shaved 0.196 seconds
3.39 mph faster
1/8th mile shaved off 0.351 seconds


This is a noticeable improvement, but car is still not as fast as it could be.

I have not weighed the car, but it is full dressed with spare tire, 8 ¾-3.55:1 rear, disk brakes, power steering, sound deadening, sub frame connectors, duel exhaust, and a fat bastard driving… So I suspect it is on the heavy side as these cars go.

Back to the car show; there were a dozen or more real nice Mopars in attendence, much much nicer than my heap, that showed up including a perfect yellow 71 Hemi Cuda ragtop clone. A nice end to the car show season around this neck of the woods.

Very cool to make some improvements and enjoy a day of "car stuff".

You've got a couple typos on your times. (660 ft is the 1/8th mile - 1320 is 1/4 mile). Unless you REALLY made some improvements and ran a 10 second 1/4 mile!

You're being modest about the condition of your car. It's beautiful! I've got pictures!

Thanks Rob,
1320’ revised to 660’.
3.39 seconds revised to 3.39 mph faster.
Damn brain farts.

Hard to concentrate on racing when: sitting with bare face hanging out while track is being de-oiled for an hour; car show under way; in need of a wiz; and thinking about red hot dogs & onions…

I should head over next year during normal operation without the sideshows a few times.

I’m considering upping compression to mid-10’s, or whatever calculations dictate to get DCR up to around 8. I think that will perk up the old slant a bit more with some low end grunt.
