I recently bought a 85 pontiac 6000 with a six cyl multiport the engine is bad ie. rods knocking in lower end. I want to know what my direct bolt in options are here. do I have to go with the same 2.5 or can I move up to a 3.8 or god forbid cn I squeeze a small V-8 in the little devil.
come on fellow gear-heads lets see what you know.
and what we can figure out.
I only paid a hundred bucks for it so I can put a few in the engine.
