Yes, ls1 will fit on lt1. 28# injectors came on the LS1, but they flow the same amount as LT1 injectors. This is due to the LS1 having a higher fuel pressure. On a LT1 they will only flow 24#. An AFPR won't help either, just get bigger injectors.

nada, nothing, zilch. you get the picture.

Unless you have a 93 which had 22#ers, but even then you'd have to reprogram and there's no hp gain from them.

You can send a few my way if you want. I wouldn't even think about upgrading injectors unless:
1. Your stocks ones fail
2. You put in a N2O dry kit
3. You get a cam large enough to require them (230/236)

Good luck and let the modding begin.
