me and my uncle were arguing a shop in my area is selling this mean fully built block the only thing stock on it is the crank it has +1 oversized valves it's a boosted setup I was going to remove all accessories and turn it back to na till I can get the proper fuel rail injectors maf fuel management manifold setup bla bla bla to run the stupid numbers there shop car is running.
My uncle thinks that the oversized valves will max out a stock pump and injectors. My argument is with a stock maf and ecu it couldn't possibly be allowed to take in enough air to max out the injectors what do you guys think

I mean if nothing is stock and you have a different CR, bigger cams, headwork and a bunch of other stuff done to it why would you think the car would run right with a STOCK ecu?
