86 318 build
First idea, limit curse's.
The 318 can be a real fun engine. I have done several of these little mills with spare parts to full rebuilds. the first issue with the 318 besides the lack of displacement is there low compression. Adding 360 heads for better flow and bigger valves is a good step, but, the large chambers kill what little compression you have. The heads will need to be milled down a good .060.
From here, basic hot rod parts can be installed and added on. The question of the day is, "How much power do you want and/or how fast do you want to go?"
