Put an "dont scold" 1406 Eldebrock on 4.3. rejetted to .089 primary .092 secondary pink spring 68X57 rod. Took out to run and two barrels worked fine. When I got into the four barrels it would labor. Now discussed I opened the cowling and removed the air cleaner to watch the secondaries...
I recently purchased a 83 with a mercruiser drive with water in the oil. My plan was to put a 4.3 i have in. What I did not know is the engine in the boat is a 3.8. :) Are these two engines interchangeable and if so are there any major parts that need to be purchased to make this work??? thanks
