Twelve pages of posts are a lot to go through so forgive me if this question has been answered:
What is the best option for EFI on a 1969 318? If I use the Pro-flow 4 I think I have to upgrade my original heads to 340-360 at a cost of about $2k. At this cost I start thinking about just going more modern and getting a mid-90's magnum block with a roller cam but then the Pro-flow 4 manifold doesn't match the bolt pattern of those heads. Thoughts?
