Finally, it runs !!!!
You'll have to take my word for it that it actually runs. Phone battery died.
But it does indeed run although there are a few items to fine tune before driving it:
Stock tune for 5.3 (including injectors) but it is speed density.
Motor has Magnacharger supplied 42# injectors so when you goose it any, it smokes like a pro stock diesel pulling tractor (and I'm not kidding).
Motor has 224/230 cam
No O2 sensors in the headers
A couple tiny leaks to knit together but it is ready to drive after those things are addressed.
Few things in life sound as sweet as a cammed small block with open headers.
