car dies when I give it throtle

I just put this motor in, It's a 2.3 out of a 1989, and I put in my 88 vert.

it idles great just when I give it the gas it dies (in record time)

there was no gas in the tank and I put about 3 gallons in also I had to take the fuel rail off my 88 motor and put it on the 89 because of some broken fuel lines. there isn't any vacume leaks or fluid leaks anywhere, just can't give it throttle

any ideas
