Sizes

I'm not familiar with any particular issues with that model, but 305's generally used 19lb/hr and 350's used 22lb/hr.

As brianp454 said they are 22 pounders. Below is a chart giving possible part numbers.

If he's a good friend, I would sell stock, untested injectors really cheap even if they have low miles. Things may have deteriorated since 1989.

alright, another question...his motor is a 305, with ported stock heads, and a mild cam....he thinks it puts down some mad power, but the person he bought it off of had it in a monte carlo with 4.10's in the rearend, so i think people thought it was so fast just because of the low gears in the *** end...i know the engine has stuff done to it, but i don't think its as crazy as he thinks...there is no sound of a lopey idle or anything like that, so i think its built up, but not what he thinks it is...he's putting a TPI setup on there and ditching the carb before he puts it into his iroc..It is the stock bore and stroke, do you think 22 lb injectors will be enough for him? He's worried about not having enuf gas flow...what do you guys think? how does like 50-75 bucks sound for them? otherwise he's gonna buy a set for like 150-200 brand new....

22lbers are enough for what he has. I actually bought a set of 22's off this site for $40 and had them flowed just for safety's sake for another $40 and they were perfect. So if your's have been flow checked then I would say $75 would be fine, but if they have not then you can find used injectors for cheaper than $75.
