The turbo 6.5 replacement chain set is quite expensive. The best alternative is to buy the early 6.5 N/A set and throw away the crank gear and reuse the orginal sprocket. The Mellings chain set P/N 3-1815 works quite well on the several engines that we have done. The chain fits tight.

Save $100 bucks! Hope this makes somebody a Merry Christmas!
