There's a slight error in your question. The 1986 Jeep Wrangler did *not* use a 350 cubic inch (5.7L) Chevrolet small-block engine. The 350 Chevy is a very common engine, but it was not offered in the Jeep Wrangler during that year. Wranglers in 1986 used much smaller engines, typically a 2.5L four-cylinder or a 4.2L six-cylinder.
To answer your question accurately, I need to know the correct engine in your 1986 Jeep Wrangler. Once you provide that, I can give you the proper timing and firing order.
