I converted my freshly rebuilt GM Crate 350 running a 600 CFM Edelbrock Carburetor to a Holly Multiport Fuel Injection Kit 550-810.
They ran a baseline before and noted the Carb was running rich and then ran a baseline afterwards
They also swapped my fuel pump (went for an inside tank pump) and Distributor
I am not smart enough to answer questions about these plots, but thought it would be of interest to those thinking about the change.
I know if I want more power I can swap this setup to any GM small block engine and it would just need to be retuned
They told me they were measuring the HP at the wheels. I do have 32" tires.
As you can see there is significant Horespower increase and it doesn't start to drop off at 3500 rpm
Torque is improved but not as significantly
The second HP plot focuses on the two runs rather than 4
I am not sure what the last plots are telling me. I am sure someone here is
And the most important items:

And the most important items:
- It starts with the turn of a key without having to give it gas
- It runs much better and I won't have to worry about dying in the mtns or in an incline
- It feels faster, not what I was going for
