Just replaced my 5.7 vortex with a brand new crate engine, everything went good but now it’s throwing the infamous p0300 code and just wondering if anyone else ever had this issue or knows what I can do to fix it thank you

I’ll definitely take a look at that in the morning! I appreciate it.It's running lean based on your short-term fuel trims (fuel is being added -- a lot!). One possibility is a vacuum leak, or something else could be causing that. Check the intake from the MAF to the throttle body to be sure there aren't any leaks in that plumbing. It could be a hose left unplugged, or damaged.
It did not come with anything but I did replace the distributor cap and rotor, along with new plug wires and plugsDid the new motor come with new ignition components?
My '99 Hoe had a P0300 and it wound up being a bad distributor cap, that was replaced just months before the issue arose.
The new cap resolved the issue immediately.
