Which Carb/Intake Combo?
I'd go for the 650 Eddy Thunder Series carb.
I have tested the Ede 600,650,750 on my 360 Dart.
The 600 runs like a champ, only missing out on the very top end to the 650.
The 650 is the best all around running carb of the 3 on my Dart.
I never could get the 750 to run as well as the other 600 or 650.
All of these test were on a mild 360 with RPM intake.
The reason I suggested the 600, is for a couple reasons.
1. Its going on a truck, where low end and drivebility is what you would usually look for.
2. Because they are inexpensive $. People are practically giving them away. Where as the 650 is kind of spendy. I also like Edys for the fact that they hook right up to the factory linkages.
Economical, reliable, performance, easy use, RPM Ede 600 my choice.
