will they work with the stock L31 manifold and injectors or will i need to buy new ones?

i just bought a 5.7 L31 vortec engine from a 99 tahoe, it has the complete wiring harnes but no ECU, im going to retro-fit it in my 76 camaro, since ill be looking to turbocharge later i would like to know what OBDI ECU would be good for my engine (OBDII tuning programs look kinda expensive)
