AND: I'm not a poser and don't just want the rough idle...I want it smooth with daily driver qualities but with a lot of low and mid range power! The mill goes in a 67 Chevelle, TH400, 2500 stall with 3.55 gears.
The guy offered me a cam swap - what would you do?
thank you very much for your help!!
If a smooth(er) idle is a prioriety, change the cam.
Find a cam with 218 to 226 @.050" intake duration 110-112 or 114 LSA and .500-.520" lift at the valve.
Like this Lunati cam
