91 dodge d150 2wd 318

I can't remember if one of these is TBI or carb, but I'm thinking TBI.

When did they go multi port?

Thanks

TBI 93 would be multi port IIRC

'92 was the first year for MPI, I would check it out anyways because I looked at a "91" W150 a while back that was really a '92 with a 318 mag, it had a title issue and the state re-issued one listing it as a 91 since it was built 8-91.

Thanks guys
