Hi all. First off, I would like to thank everyone on the forum who has helped with parts or info on my project. It's up and running and hauls butt. You guys have been invaluable. Now, on with my problem.
My project has been building and installing a 318 in my 66 Valiant with a /6. The engine has stock pistons with heads shaved .40 and gasket matched and minor polishing . I have a Performer intake and new 600 CFM performer carb. Running stock exhaust manifolds and dual exhausts.
Timing is set at 12 initial and I think 36 all in. The cam is a Summit cam and lifter set with .421/.444 lift and 278/288 duration. I think that does details.
Anything I have had with a cam before has been radical or stock...no in between. I kinda thought it would be almost unnoticeable. By the way, I have checked the carb and the floats are good and have fiddled with the mixture screws until I'm afraid I might wear them out.
My thing is that I cannot get the car to idle smoothly. Should it?
Sorry for the long winded post but details are necessary. Thanks. Dennis
