Default right size injector 427 cui ?

Hi, my friend bought a 427 engine C5R block, it was delivered with
28.4 injectors, stock GM 350 cui size ?
I find this hard to believe, can this be right ?

On Dyno pull, injectors max out, highest duty cycle is 103% :-)

Anyway, anyone know what size is correct for a NA 11:1 427 cui ?


TIA

It was recommened that I use 42lb on my 436 but Wade told me I could probably get by with as little as 36lb er I was using in my blower motor, I would rather turn down the 42's than run the hell out of the 36's, if Cartek is using 37's in Marco's 427 and I'm sure his CR is 11 to 1 I would use that as a rule of thumb--
