Hello Guy's, I opened and cleaned my original Carter completely, during this cleaning I install Edelbrock 1403#( 500cfm) on the top of my engine. Thinking that there comes some performance/ fuel economy improvement. I made testing and tuning by changing rod's and jet's, leaner/ richer.
Best combination is, Primary .086, secondary .095 and rod 065/047. I made acceleration test wher I used rev 2000-5000 as a base and used time was what I measured.
Once Carter assembly was ready I but that back on the top of the engine and it beated eddie even that it is 50 years old with factory setting.
Primary 489# => .089
Secondary 120-374# =>.074 or .073? ( don't know which one is correct)
Rod 16-403 is with three step, measured .067 x .063 x .056.
What is original 16-403 rod size? I have read and seen several measures and still wondering what is correct?
Other question is, can I use Edelbrock needels and jet's on my Carter? Primary jet is longer originally than what is on Eddie's tuning kit, how about rods, they are two step and original one are with three step needels?
I believe that I don't need to touch Carter jet's but I like to make at least trial. What is your suggestion or have You done this allready? If I want to go leaner or richer, any ideas what rod I should use and can I get anymore three step rod's?
Fuel economy I have't followed, what is your opinion, which one I should use, original Carter or Eddy 1403 or others.
