1964 Dart Grüne Hölle Road Course/Track Day/AutoX Project
9/20/21:
I swapped the Step-up piston springs for the metering rods in the Edelbrock 500 Carb from 4" hg to 3"hg - It really needs 3.5"hg Springs but I don't think Edelbrock makes such a part, or a metering rods with 3 stepped areas - I dont think those are available any more either.
With these springs it's a bit too lean at moments on the throttle, but does not get into the 12's / 11's AFR in 4th / 5th gear on the highway when pulling a small to moderate grade. With the 4" hg springs it was wasting fuel in this area... Carbs can only do so much with their notchy tuning abilities I guess. For my next trip to a 24 Hours of Lemons Race in Kentucky, I will set it up for good MPG's instead of all out throttle mashing fun.
I also Was invited to the season wrap up meeting for the Pittsburgh Vintage Grand Prix organizers..
It was on the North end of Pittsburgh, about ~ 40 from me.
Parking was for "fun cars" and boring cars. I parked with the fun cars. Was a fun trip and got to meet a bunch of new car guys and gals that help to put the 10 days of racing and charity events together. Also found more wonderfully curvy roads / hill climbs around the Pittsburgh area. -
