I'm helping a friend swap a 2005 L33 (Aluminum 5.3) into a '63 Buick. The motor is stock except he had to remove the truck intake and injectors for an intake and injectors from a 2001 LS1 for hood clearance. The truck injectors are part number 25317628 and are supposed to flow 25.2 lbs/hr at 58 psi. He had the LS1 injectors flow tested and they flowed about 29.8 lbs/hr at 58 psi. Are these injectors close enough to run for a baseline, or am I going to have to copy the tables from an 2001 Ls1 before we start it to be safe?
EDIT: The LS1 injectors were supposed to be off a 2001, but the part number is 12555894, which is a 99-00 27.3 lbs/hr injector. Funny thing is they tested 25.8 @43.5 pounds which would be 29.79 at 58#.
Thanks
Steve
