I will be running the Edelbrock 1.90 valve heads with minor porting and edelbrock performer manifold with either a E303 or TFS cam. Also I want to put 100-150 shot of nitrous on it. What size injectors should I run? Oh the short block is standard 302 not a stroker or anything like that. Thanks for anh advice.

if u are also running an intake (u didnt list but i will suppose ur are duh), go wit the 24# if the nitrous kit is wet, or 30# if the nitrous kit is dry, go with bigger injectors for the dry kit because the extra fuel goes through the injectors, i have 24#'s on my cobra with a systemax 2 kit, that kit has a little more power than ur i think, my injectors keeo the air fuel ratio at about 14:1 all the way until redline, if i may, get the zex nitrous dry kit, its fuckin awesome

I would just go with 30lbs so you have room to grow. Remember to get a MAF to match those injectors as well.

the only problem with that is that he will be so rich down low he will have no low end torque, my friend has a 351 lx, puting over 425hp to the crank, and is running over 24#ers without a problem

I agree. I ran heads/intake/stock cam w/ 1.7's on the 19's and ran 109.45mph with only 44psi fuel pressure. Just upgrade the pump and use the adj. F/P regulator and the 24's will be plenty. You may find it even runs best w/ less than stock F/P (~39psi). Trust me...

I will be using a performer Intake. I was looking at the ZEX kit because of the ease of installationand the fact it uses the TPS for activation but then I saw that NX express. They offered a wet kit up to 150 where as the ZEX is only 125 dry.

Have you ever thought about Holley's NOSzle nitrous kit? They offer anywhere from 75 to 300 shot of nitrous, and its a wet kit also.
This way, you could use 24 lb injectors, and still be spraying a 300 shot of nitrous if you desired. This is what I would use if I were to buy nitrous. The only problem is, this nitrous kit is a little bit more expensive then some of the others. Just take a look at it, and see if you like it. Either way(whether you get this kit or another) your car will be running pretty fast! ![[burnout]](graemlins/burnout.gif)

Will you be running a wet or dry kit? Will you get a custom chip/dyno tune?

Iwould like to run a wet kit but people seem tp like the dry ZEX kit I am waiting to hear feed back about the NX express we kit. I also would get a chip if that would pull a few mor HP with the NOS.

If u are goin with an alphabet cam, i would actually run the F cam, tend to be a bit more N20 friendly.
