I was (finally) able to get out and do some testing in the good fall air this weekend.
Resulted in a new personal best: 9.85 @ 136.87 mph. Backed it up with a 9.88.
This could be attributed to the addition of Q16 race fuel, jetted up and re-set the timing. Baseline for the day was 10.07.

Way to go! BTW, how many times a month do you paint your car. Every time I see it, it is a differant color. JB

Thank you, but I'm not sure I know what you mean about the color;
It's been black since new, although it varies between "dirty black" and "needs to be wheeled out" black, up to "freshly waxed" black....

My monitor or video card is a little off. For some reason I keep thinking your car was dark blue. Oh well, I love black. If I did not have a green interior I would paint mine black. JB

I think the look varies depending on the sky and other things in the background...
that's probably why the magazines don't like black feature cars...

Say, Keith,
What kind of rear end do you have? What mods did you do?
Many thanks!

Thanks for askin; it's the original 8.5" 10 bolt that came under the car. On the exterior of the axle I've changed the attaching points a little bit to improve the rear suspension instant center, and the tubes are welded to the centersection. Inside, it's got Mark Williams axles (with C clip eliminators) and a MW spool.
Ratio has been anywhere from the original 3.42 all the way up to 4.88. Currently it's back to a 4.10.

Best ET is 10.01 @ 136 mph with Mickey Thompson 10.5 " slicks through 4" Flowmaster mufflers (1.400 60 ft time); Since 1990, I have been running select "Super Chevy" magazine events, select BTE/Citgo Series events as well as the full National Street Car Association Series. This car has been run at the following venues: Phoenix Firebird Raceway, Bakersfield CA, Norwalk OH, West Palm Beach FLA, Atlanta GA, Mobile AL, Joliet IL, St Louis, Cecil County MD, Petersburg VA, Martin Mi, Milan MI, Grand Bend Canada, Salem OH, Stanton Mi, Columbus OH, Memphis TN, Union Grove WI, Atco NJ, Bowling Green KY, Ubly Mi and Lapeer Mi.
Just updating the list; best ET remains at 9.85, but I can add Phoenix Speedworld, Indianapolis and Thompson Ohio to the list of tracks visited.
Remaining events for this year are planned to be:
July 12-14 in Joliet
August 2-4 in Bowling Green Kentucky
August 23 - 25 in Norwalk Ohio
and October 10-13 in Indy
all with the National Muscle Car Association.
This year marks 35 consecutive years racing this same car.

Looks like we are done for the year here in Michigan, so I thought I'd give an update for this season:
I spent a lot of time away on business (building G vans in Wentzville) - so I missed all of the NMCA events on my calendar - but I did manage to make it out twice this year.
I've been participating in an "all motor" series sponsored by the Renegade Race Association. They alternate events between Norwalk and Thompson Ohio. They have an 8.90, 9.90 and 10.50 index to chose from; since I'm legal only to 10 flat I have been slowing the car to 10.50 and running that class.
I'll tell you what - I don't know why we go anywhere other than Norwalk to race. That has got to be the nicest facility in the known universe. New guy here qualified #2 (out of 18 cars) right off the trailer
Of the 18 guys in the class I'm pretty good friends with one guy, one of my Pontiac buddies. Guess who I was scheduled to run in the first round?
Yep. He was a nervous wreck. We waited until 8:30 pm to run our first round...
and then....we got rained out.
Second race was in Thompson, which is a bit smaller facility. Qualifying was tough, with 10 guys all running within .001 of the perfect 10.50 run. First round my opponent broke at about the 1000 foot mark so I coasted past for an easy win. Second round....the rains came again and we were done.
I think I need to find an indoor sport (or, that said, I'm a huge proponent of indoor drag racing!).
So - that's probably it for now - unless I can sneak off and do some testing locally. Looking forward to not having to cut 4 acres of grass and using that extra time to get some work done in the garage...

Norwalk (aka summit motorsports park) & Thompson... You must live somewhere somewhat near me as those are my two closest tracks. Thompson is about 45 minutes away, and norwalk is a hour and a half away.

Detroit area. But I'm used to driving - I used to run the full NMCA/NSCA schedule (Florida in March, Georgia in April, Virginia in May, etc, ending up in Michigan and then finals in either Columbus or Memphis in September/October).
Norwalk's about 3 hours for me, and Thompson maybe 5 or 6.

I was wondering how you got your car to set almost level with 2in drop spindles in the front ?
How did you get the rear down on those 29 in tires ?
I have a 76 EL camino im going to put 2 in drop spindles on but i would like to bring the backend down also i already have two coils clamped almost together to bring the rear end down it sets ok right now but i want it just a little lower like your car fenderwells just above the rims & tad bit higher mid tire in the rear almost what you have going on ! And i read somewhere you have a wagon spring in the R/R so i can not figure out how u got it to have the Great stance !
Any sugestions for my elcamino to get the back lower im runing OeM springs in the rear

I have production spindles in the front, but cut coils (probably one coil for a 2" drop).
I honestly don't remember doing anything to drop the rear. I do have a wagon spring in the right rear - plus an airbag which I preload with 20psi at the track (so the rear of the car is pretty jacked out of shape at the track).
The rear wheelhouse on a Chevelle may be different than an El Camino. I have no issues sticking a 29.5x15.5 Mickey Thompson (13.5" wide) in the wheelhouse. The frame was the limiting factor for me.

2020 Race Update:
Finally made it out this year with a new motor.
Broke the end off the crank at Indy last year. Got the new motor completed, dyno'd, and dropped in the car with a week to spare before heading to the NMCA (National Muscle Car Association) Finals at Indy the last weekend in September. (No sense waiting until the very last minute - lol - the global pandemic put the kabosh on my ability to expedite the build).
The new motor is a Scott Williams built 572 cu in big block based on a GM Bow Tie Pro Stock CNC block and Callies crank. I'm re-using my AFR heads, Dart intake and Dominator from the previous 555. Engine dyno'd at 850 HP at 6500 rpm and 740 ft-lbs torque from about 4800 to 5800 rpm.
That translated to a number of low ten second passes at 3900 lbs. I ran the 10.25 index for my Nostalgia Muscle class and was shooting for 10 flat in the True Street categories. Best passes in True Street trim were 10.02 and 10.08, and I had an "accidental" 9.996 when I ran it out the back in NMC. The car has been 9.85 in testing under perfect conditions (mid November temps, removed the extra seats, no front bumper, no exhaust, hot tuneup on hot fuel) so this was the first 9 second pass during competition and under normal conditions (normal tune, through the mufflers on street tires).
I got some favorable press in the form of an internet mention during the daily highlights; as a result of that honorable mention we did a photo shoot for future print publication in the NMCA magazine, timing tbd.

2020 Race Update:
Picking up where we left off, since the 2021 season is basically a continuation of 2020 -
First outing was Atlanta, held the second weekend in April. Not sure what I expected but it was hot. Hot hot. Did I mention it was hot?
I was all out of sorts: left the house later than expected, got to the track later than expected, which committed me to run a class quicker than I should have. The car really wanted to go between high 10 teens and low 10.20's - which just wasn't enough.
My three run average for True Street was 10.17 (which just wasn't enough for the 10.00 index). Same story for Nostalgia Muscle Car eliminations: I cut a Perfect Light** but the car went 10.21 on a 10.00 index - which just wasn't enough.
Next up was Gateway Raceway in Madison Illinois, last weekend of May.
Holy Cow! what a different story. The "air" was phenomenal. Like "so perfect" it drew attention to itself. I don't think I've every raced in such air, and certainly not with this new motor.
I uncorked a string of 9.80 runs which, since the car is legal to 10.00, got me in trouble with the tech officials. After a couple conversations we agreed that if I would wear the appropriate clothing (SFI 3-2A/5 jacket and pants, gloves, shoes and neck brace, as opposed to my usual 3-2A/1 pants and jacket only) they would give me a "one race waiver" on the car (cage and window net).
With that newfound liberty I was able to slow the car closer to 10.00 without the fear of unintentionally dipping into the nines.
End result: I won the True Street 10 second index with a 9.96, a 10.06 and a 10.02 for a 10.02 average. Also went a couple rounds in the Nostalgia category so I can conclude that a good time was had by all.

Remaining events are:
Martin Michigan - July 23-25
Norwalk Ohio - August 27-29 (I have to skip this one because my daughter is getting married in my back yard)
Indianapolis - September 24-26
**Drilling down a bit on this "Perfect Light" situation: it took me about 28 years before I had my first perfect light.
In more modern times - I had one at Indy last year, the aforementioned one at Atlanta, and then again one in St Louis! One for each of the last three events in a row!

2024 season is complete, with attendance in Rockingham (April), Martin (July), Norwalk (August) and Indy (September). Just missed a Top Ten season championship points finish by one slot.
Then - the association announced they have gone bankrupt and will not fund a 2025 season. I'm feeling a bit adrift; I have been with the NMCA since 1994.

So I treated myself to a test session in the cool fall air.
New Personal Best!
Went 9.56 @ 139 mph at Milan Dragway.
That's footbraking, naturally aspirated, on a DOT tire and through the mufflers, I might add.
