1964 Dart Grüne Hölle Road Course/Track Day/AutoX Project
6/11/21:
Got a few more Small things done.
Ordered some more rod / jet combinations for the carb.
- I still want to try to get a better / smoother transition between the lean and power settings on the primary metering. It's a Bit Notchy now.. Some of the old OE Carter Rods had 3 steps on them to help with this issue... but the aftermarket edelbrock ones just have 2 steps.
- Note to self: Put MPEFI on it and get it tuned better... Maybe next winter / summer.
I put a Jones Exhaust Resonator in the tailpipe... this was a major win for me as the burns 2 stage quiet muffler was really too loud for the street and I would surmise probably over the 98dB sound level for SCCA and other decibel monitored track events.
This 14" x 4" Resonator placed in the tailpipe attenuated the "bag of angry wasps" sound that was annoyingly prominent around 3K RPM with only the Burns Muffler.
I also swapped from 175#/Inch Springs to 200#/Inch Springs. To help when the car is loaded with passengers and fuel / Tools etc on road trips.
Today I will do a few more maintenance Items:
- A good once over on the valve train.
- Setting the Hot Lash and Checking to see if the Roller Tip Rockers are doing okay without a spray bar in the Valve cover..
- If they are not, then they will be swapped to Stock Rocker Arms.
Planning a Nice Car show trip on Sunday to Ohio.
