Is '90 Astro throttle-body or multi-port?

I'm hoping to be able to swap the 5 speed manual tranny from my '86 to a '90 that has an automatic. The mechanic says the engine (recently rebuilt) might need to go along with it. The biggest problem could be if the '90 has multi-port fuel injection since the wiring is way different from that on the '86 since it has throttle body injection. Anyone know about these things?

What the 8th digit of the VIN?

Z=TBI
W=CPI

They both have a Z in the 8th digit. Good to go! Thanks!
