88 IROC TPI engine swap help!

Ok, im sure its been posted, and my pc acts up and i have trouble getting access, so im wondering what is needed to swap from a 305 tpi with a 5 speed to a 350 tpi keeping the 5 speed for now, till i can afford a 6 speed swap. the car is complete, and i have an engine to put in, with all accessories. from what i can find need a different chip, injectors, and fuel pump? what other little bits am i missing out on? i know the 350 can destroy the t5 quick, but its for cruising, not racing. eventually i would like a 6 speed swap. thanks guys. this is really needed, cause i have to put something together so i can have a DD.

Knock sensor is different in a 350. Follow the link for more useful tidbits:
