Your welcome.
Its a 65 plymouth belvedere if that helps.
Guys on the board have really helped us with chassis and other areas.
we also added a 1200 twinblade and Dom ( Thumpercarbs ) has certainly been a factor in improving the car.
If i can get this Duster done, see what it does and its basically the same ideas from the op- simple, strong, low maintenance stuff that just works.

Imho: best single item anyone can buy is a af meter with built in data logger so you can see your afr for the whole run on a computer screen.
We build cars here and install them as standard equipment - customer has an engine problem i can pull the last logs and see rpm, afr, vacuum and those three certainly help with diagnosis .
Race cars: even with classes that don't allow taking data, one can get on top of things during "test n tune " and its just charting weather after that because you know where you are.

To date- every car i have tuned with one i have made faster, its one of those 'best hp per dollar " deals to me.
Aem makes a nice little single unit that works very well.
imho
