There may have been some confusion, the 1200 idle is only cold while on fast idle and the choke on. Normal driving when warm the idle sets around 600 and idles quite nicely. As far as timing, carb, tune up, etc... The motor runs great and is very responsive. Timing is at 10 degrees and currently vacuum is setting around 14" the best I remember. As of now the only concern I have is when shifting to reverse or drive it "lurches" a little more than I would like and was considering a stall converter for the reasons above. The 383 build is around a year off, so not in the immediate future. I'm still saving, so I can do it right.

Currently the 350 is running 9.5:1, Edlebrock performer rpm cam, world aluminum heads 2.02/1.60 with 64cc chambers, 1.5 ratio roller rockers, Performer RPM intake and a Edlebrock 1406 600cfm carb. When the 383 is done, I was considering a little larger cam with longer duration with intake and carb to match but this will move the rpm range outside of how the truck will be driven, so I may keep the rpm cam.

@Potvinguy, There is a cooler installed, but I'm upgrading it to a fan driven cooler when I install the converter.

Since everyones experience is above mine, feel free to let me know your recommendations.
