im not sure on the size. they are stock 350 vette injectors from an 86 unit. Engine is a stock 260hp crate engine. Nothing else. May change cam and headers in within next year, but in no hurry. I want to make sure i get a injector thats as trouble free as possible. Car is normally driven on weekends and planning on some extended trips with it soon.

I think that narrows it down to the injectors, but I would change out the FPR anyway.
I believe the one to get is the HLY-512-501 and the FMS-M-9593-A302 injector. Ford's are direct fit and have a better quality reputation than the Accel.
Stock is a 22lb injector on 86, so you will need the adjustable regulator to turn the pressure down a bit.

Normal psi on a L98 is 36-42 psi. I would set it anywhere in this area. Too much may be rich and too little may be lean. Putting the car on a dyno will get you what you want. Checking spark plug is a easy way to tell if your in the ballpark.

I'd probably start at 40psi and work from there, pay attention to gas mileage, plugs, and whether it smells rich
only way to get it perfect is track testing and/or dyno

ok..im back from Summit Racing and picked up the Holly adjustable FPR. The guy there scared me from using the FMS injectors saying that the fuel rail would have to be modified. I instead went with the Accel 23lb injectors. Hopefully they will work fine.
When i got back i disassembled my fuel rail
i popped the first injector out and a rust like, milky substance dribbled out. Im guessing that the seafoam broke loose some tank/line rust that the gasoline mixture couldnt dissolve. I took the whole rail assembly apart to give it a good cleaning. I have a feeling this is what stopped the injectors up. Another sad part of this is that i forgot i didnt have a fuel filter. That problem has also been solved. The tops of the injectors as well as the tips where in bad shape. Maybe this will now get me going again.

I think you'll be fine with the Accel injectors. One thing to do is ohm them before install. Should read about 16 ohm +/- one or two. Just replacing the injectors isn't all that hard. Make sure you have the injector clips on to prevent taking it back apart later and it would be a good idea to get new fuel o-rings for the feed and return lines where you have to disconnect, to prevent leaks later (brown o-rings for gas). The injectors should have come with o-rings and just put a little oil on them and they should press in pretty smoothly. Yes, damn I forgot to tell you to get a fuel filter. I would also get some of the gas, if not all, out of the line prior to install. Good luck.
