4.3l Injector size?
I recently got an intake from a 1995 caprice with the 4.3l v8. I have tried to find what size the injectors are. Does anyone know? thanks

Best for sure way to know.....get a part number from off the side of injector, search on that.....Some lt1 motors (93 corvette) run a small injector, so that one I would suspect to be 18-22lbs

Re: 4.3l Injector size?
I think they were 200 HP and 240-250 TQ depending on the year. It is basically a 305 version of the LT1 with a 3" stroke crankshaft and 5.94" rods. (3.735" bore and 3.00 stroke) The cylinder heads are almost identical to the L30 305 Vortec.
On a 1994 Caprice the stock injector flow constant is programmed at 19.45 lb/hr.
