The cylinder head development, lost track of the flow bench "pulls"... process work for the CNC...all of the machine work...countless mock-ups...screw-ups...$$things that do not fit...nights of camping out at the shop in Tucker..42 (or so) passes on the dyno.
The last few months have been pretty wild.
But, it does sound pretty good... Smile
Once it is hooked, it should fly...

Wheelie58 wrote:Ok...the story. It was a few nights before Christmas.
The 618 was all tucked in and happy in its new home. The elves worked their asses off.

So..The day was very pretty, about 54-56 degrees. It was a test-tune day at the track. SGMP is a fine Divisional level NHRA track. The track was very cold. Lots of street tired cars dragging fuzzys on the line...no spray...
I only got to make 4 passes before the session ended.
First pass, timing at 27 and no retards. Engine was just like it came off the dyno. The first pass scared the crap out of me. I returned wondering what I was going to do with this engine. It left pretty nice, began spinning the tires... got crooked...I lifted, straightenedand hammered it again. Lit the tires again. This happened 4 times until I finally crossed the finish line at 130 MPH...kinda spinning the tires. These are brand new (last night) Hoosier 15x33s. I was thinking about Wille Borsch and his tire spinning altered... affraid
Second pass... cranked in a 15 degree starting line retard, ramping it off 2.5 seconds out. I also applied a 15 degree retard for the rest of the run. Timing is now 12 degrees. It left pretty nice and ran a nice straight 9.21 at 146 MPH. All of the ballast is out of the car, so it should be about 3650#.
Third pass, I gave it 3 degrees more timing, so it is at 15. It ran relatively straight and went a 9.07 at 151 MPH.
Rushed to get back to the lanes before they closed, but gave it 5 more degrees of timing. We are now at 20.
It left nicely, wheels up.. with a 1.29 60' (best ever for the 58) then got crooked, spinning. I lifted, straightened it guickly and nailed it again...headed for the other end...ran a 9.04 at 153 MPH. I need to look at the RacePak file to see how long I was off the throttle, but I did look at the acceleration G reading and it went from 2.0G down to .35G...then back to 2.0G when I whacked it again. It would have been my first ever 8 second run! Grrr.
One or 2 two more passes and I could have figured out a timing strategy to get it hooked.

Not a drip of any fluids, no tools were used at the track...Ok the tire gauge...
It was a smooth trip, with the old 7.3 humming along for 470 miles.
So...Yeah...the old car could use a new rear suspension. I have the latest and greatest shocks, but the 26 year-old Art Morrison ladder bar setup could be improved with a nice 4-link. The car is also very nose heavy. It needs to spend a week in Kentucky with Dan-o to get the glass doors fit and painted.
I need to ask Santa for a parachute and get it on there before the first race in February.
Thats it!
Now it is time to get the next engine in progress. The Blue Thunder 514 will not go back in the car and will most likey find a new home. The #2 mill will be another "A head" 10 liter. Just need a few more parts.....
Thanks for all of the support...and for enduring this multi-page saga.
Keith

Congrats 9.04 at 153 MPH in and out of the gas 8's are in your future for sure!!!!

Later Mark.

I wanted to go track and see it run but they told me I had to work at the last min.But this working 6 and 7 day a week is coming to a end before long if it means changing jobs.Maybe I can catch up with you next time you down this way at SGMP and help you out in the pits and get some vids of it.

It will be easy to find now. The ONLY red 58 Ford at the track that's required to have chute. Otherwise, it might have gotten lost among the other red '58's

That's a Bad AS# '58 Keith. Does that thing still have the stock front suspension? Any of the original frame still there? I remember seeing it at the bash but can't remember the set up. That thing kind of makes me want to put a big block in my wife's 57. Very Happy

Yes,,it has the stock front suspension, but I installed tubular upper a-arms for better header clearance. Over 2/3 of the original frame is there. I cut it right where it started to kick up in front of the rear axle. It is a back half, ladder bar street car that has everything needed to cert to 8.50 and pass tech at any National event. Windows roll up and down (all 4), vent wings work. Other than the back half I did back in 1986 or so...and the race weight hood, the car is just like it was when I drove it to High School in 1973. It even has the same paint that was done in about 1976 and the (now) rotten carpet that my buddy sewed up. The door panels are the same ones that Paul Johnson had in the car, when I used to hang around his shop...riding my bike at 12 years old. He was my hero...and I ended up with his car...
Thanks,
Keith

David...I have been chute shopping today for sure. Kinda messes up the plan to put a license plate and insurance on the car and drive it to some car shows, since the parachute will block view of the license plate.
Yeah..the other red 58s will not get mixed up with mine as easy now. There are so many...very popular car...
Thanks,
Keith

Hey, Keith:
Is there any reason you can't mount your chute on slip joint so you can install, or remove it when ever? My brothers Starliner was mounted on a slip joint that was mounted on the rear cross member and hidden by the flip down license plate frame. It was held in place by a 1/2 20 grade 8 bolt, and nut (sturdy).

Yeah, Wayne...I am looking at that.
My rear crossmember is right below the original "gas hole" behind the flip down plate.
