355, SR, 195cc heads, 224-230 53* 112 cam. I have some 24lbs but not sure they will work with my setup

Your setup is virtually identical to mine, and I'm using the Ford SVO 24 pounders. That size should work out beautifully for you. Just make sure you have the injector constant changed in the chip for the bigger size of course.

Re: whats the best size injectors to run?

I wish I could give you some real world results, but unfortunately my engine is still on the stand. I'm hoping to have it in and running sometime this coming month (Feb.). I can give you some specs though. 350 bored .030 over, 10:1 CR, older AFR 190 aluminum heads, complete Superram intake, 52mm TB, and a Comp Extreme Energy hyd. roller- dur. 224/230 @.050, 269/276 adv. dur., .495/.503 lift, 112 LSA. Had a custom PROM burned by Alvin at PCMforless. 89 MAF/165 ECM system. Hooker 2055 headers and Edelbrock 3" catback. Pro Built 700r4 w/2600 stall and 3.23 rear gears. From what I've read on injectors, it's been said that the stock 22 pounders are barely adequate on a stock L98. Since my motor doesn't have a giant cam and is only 355 cubes, the 24's should be plenty of injector. Usually the next step up from those would be the 30 pounders, and those aren't really necessary unless you're running a 383, or a 350 with a really radical cam. If everything goes smoothly, I'll post back up or PM you when I get the motor in and running. I'm shooting for the end of Feb./beginning of March. If I did my homework right on setting up my motor, my goal is an extremely strong midrange and a much improved top end over the stock TPI.
