Hi Ross
I hope I said on the old forum, but will do so again, I always really liked your work there. I recall you being an excellent resource to many FE cars and my pals and I always enjoy your work. And that Fast Back, well, I have one too and yours is S 'peach' !. How fast is she in the 1/4 I always wondered, I bet she scoots. Love that Mustang.
On this truck, I just share how we raced and won our trucks for FORD. We handed FORD a long row of trophies off road, and di the winners for parnelli, Walker Evans, Ben Ford himself, Larry Minor, who later sponsored the McDonalds funny car and rail, Rod Hall, and many others, James Garner even
We did a lot of R and D for Holley too, since we had the trick Heinan Freud Dynos with Fords EEE instrumentation, plus, we had the Autolite Dyno
On Holley testing, with their engineers in the cells, we always stayed at 7.
On the Ford Drag Team Winternations cars, and the 12 Ford Drag team cars we did in 68-9, we also shot for 7
Now here is a trick few recall but what the heck. and off road race truck does NOT like the cathedral bowls. We used many race Holleys, 750,850 Double pumpers, modified 780s, 750s, and changed the bowls on every one to race better, at 7 PSI. We re fitted the side hung 1850 style bowls because they take a lot more pounding and abuse, off road, and also, flat spot less in the rough stuff. I bet you and some of the old guys recall that era. Ford would budget us a bunch of money to enter 7 truck classes, and we usually won all 7. I see a truck here and wanted to add, if he plans to get her in the air, fly a bit over some jumps, and hammer her off road too, we had another key trick
We would take soft copper tubing, remove both steel bowl vents, then fabricate a u shaped tube, to plumb the front and rear bowls together. You bend the tube to go around the air cleaner stud boss, then drill 094 or so holes on the vertical axis, pointing up. These holes allow the atmosphere to balance both bowls, but during sever fuel slosh, and chassis attitude pitch and roll, aand let the fuel that tries to exit, move forward or back, and maintain supply
Same deal launching a car hard if the bowls are mounted inline, traditional. We had better luck with heavy cars pushing in to the 10s and 9s, using cathedral center swung bowls, sideways
Early examples would be Per AFX, or AFX, then Pro Stock FE's running 2 carbs, then 2 Dominators. Dyno Dons Maverick had 2 110 GPH pusher pumps out back, and 2 lines, to 2 regulators. Back then, we could run rubber, often 1/2 inch too, from the tank to the carbs.
I never know who is going how fast, and how much power we have, the goal, etc, so I want him to check a few more things
The Holley Mechanical pump says right on the box, 7.5 psi. It fits all FE's and here is my concern, that extra .5 in a way, helps compensate for the many Fords that only have a 5/16 fuel line
My 67 was always power limited by the 5/16 line that makes a lot of bends. By 68, our Drag Team cars, helped FORD re fit a 3/8 fuel line, and we went further in some cases.
Ford us, once we had a Big Block in to the 10s, and 2 carbs, we often had the good mechanical pump up front, and a carter or holley, electric pump close to the fuel tank helping
On the low 9 and 8 second stuff, a dual bung set up is good, since the launch sloshes fuel back then up the gas tank, so we silver soldered big female bungs to the back, no need for a center mounted pick up, and sediment trap
I think he has to fix this deal, reading closer, maybe his regulator has a latent issue, or defect?
Maybe debris, contamination?
I wonder if he needs a return
I do try to cover a lot of bases when I can, since it is real hard to tune by typing,,,,at some point....
I bet that if he gave you, or many other fast guys here an email, or phone call, you would dial him in just right.
You, for example, would be the kind of man that we would feel very thankful to have help fix a Hot Rod if we sent it to ya.
Keep up the exemplary work and thanks for your service...
