It won't idle for very long at 900 rpm. I was looking at the Carter carb and I think the bottom end was better because of the small primaries, does that make sense?

My HP peak is at 5300rpm and the torque peak is around 4400rpm. Basically a warmer Crate 380 (the old one, not the new 380 Magnum). Better heads and cam.

The new cam is 320 degrees duration and 108 degrees separation and I wasn't sure how much better/worse the cam would be. That's where I depend on the experience of you people.

It stays pretty clean with the Jacob's Ignition, I just wondered about the rings with a fatter idle mixture. I will try what Mr. Fixit says since I turned them 2 full turns in and they hadn't bottomed out.

I have read several books, but I could read a book on how to deliver a baby too, and without some practical experience and someone to train me that has experience when things don't always go by the book, I get a little lost. I am one of those hands on , visual learners.

Thanks again for your input guys, especially Mr. Fixit for the help in the past also.

On a side note, my flywheel is 47# and I was looking at a lightweight 30# steel one (Mopar says the 11# aluminum will warp with street use). Will this feel like a 10, 20, 30 ft/lbs increase in acceleration?
