Does anyone have any information regarding a engine swap for the 87 B2600? I have one that I bought with a bad engine, was ran without oil. I could either rebuild it or swap in a 4.3L V-6 that I already have. It is a throttle body injected engine. Has anyone done this, or am I better off to rebuild the Mazda engine? Thanks in advance. Chris

YOU CAN DO IT!!!! PUT THE 4.3 IN THERE BECAUSE YOU GET MORE POWER MAZDA MOTORS ARE CRAP IT WILL LAST ONLY ABOUT ANOTHER 150,000. IT SHOULDNT BE THAT HARD JUST GET DIAGRAMS OF EACH MOTOR OR JUST MAKE IT CARBEURATED I MADE MY 1991 350 CARBEURATED ALOT EASIER SET UP TOO!
