Corvette L98 350's have the same 22lb injectors as Camaro/Firebird L98 350's.

People have swapped from 22lbs to 24lbs and needed a chip reprogram, so its a big thing.

544's are known to go bad, I wouldn't use them unless they are fairly new.
Those are the ones they call multecs.

Re: 23# injectors, made by Rochester

I put in LT1 injectors in my car. 24# Yes I did have to have it tunned. But My stock ones were only 19#. Dont forget a adjustable fuel pressure regulator.

I know they make SVO 19# ones. I'd look on Ebay.

Re: 23# injectors, made by Rochester

I just got accel 23# to replace the accel 30# that were in there. I know the stigma about accell injectors, and on the 23# box it says new design.. and they really look better ( higher quality) than the old design 30#'ers
snd he was running the stock prom with the 30# injectors... ran like CRAP...
now its 350 wit h bbk 58mm TB,headers, an 23# injectors with a custom PROM.. its not all back together.. but soon... hope the T5 holds up...
