97 gmc 306 votec swaping for a 90 305

Asked by Dusty Ray Mar 22, 2018 at 12:48 AM about the 1997 GMC Sierra 1500 C1500 SL Extended Cab SB

Question type: Maintenance & Repair

Have a 97 gmc with a 305 vortec and a 5 speed
manual. Truck is in good shape. But the engine
has 230000km and getting tried. Can buy a 90
chev with a 350 with only 150000km for a very
good price. Seeing how my 97 has more modern
electronics and is a 305 not a 350 how will it work
dropping in the older 350 out of the 90?

Thank you!
