[bowtie65]

hey guys does a 94 5.7engine plug and play in a 90 k1500 with no issues....i know its 88-98 but i hear conflicting stories and 88-92 is what fits my 90...Does anyone know for sure......thanks

Still TBI? It'll probably plug right in. The one thing I can think of is the TPS - round plug vs flat plug.

hey eric thanks for the reply...yes its still tbi....what do mean by the tps round vs flat....the connector for the tps in harness??

The fitting on the TPS changed on newer TBs from flat to round but, you can get an adapter from here.

I did an engine swap on my 1989 Shorty. It had a 4.3 V/6, and I swapped it with a 5.7 TBI. On the advice of a good friend who has been a Service Manager at Chev Dealership for over 30 years, "find a donor of the same year, and it'll just plug and play". So my advise to you is: find a donor of the same year. My 2 cents worth of advice!
