Just read this entire thread. Not interested in swapping my 250 at this point but down the road....
That said, I'm NOT interested in the computer control. I saw one photo (Howell??) of an engine with carbs and what appeared to be a distributor running of a gear/cog belt from the front engine pulley.
Has anyone done anything like this? The intake manifold is easy. variable cam timing and how to defeat it?
