I like the c6 automatic, and I like automatic tranny trucks myself for hitching up trailers and manuevering around tight places.

Franklin, I respect your knowledge. I'm knew here and learning a lot. My question... I have an 83 bronco with 300 inline 6 and a 4 speed. I want to swap the 4 speed with a sm blk c6. Will I need to shorten the drive line along with all the other conversions. Also will I need to replace the radiator as well. Thanks

Hi Franklin2.You have it backwards.The 302 uses a 28 or 50 oz external balance depending on year of build.The 300 is 0 balance on the flexplate or flywheel.The 300 is an internally balanced engine.
Good luck.Have fun.Be safe.

Whatever, we are all on the same page.
