383 in 68 Dodge Dart? new build

I haven't spent $7k yet to go big block, but oyu need to have a plan and stick to it. For starters, every upgrape you will need for a 400hp 383 is necessary for a 400hp 360, so the cost of suspension, brakes, cooling system, etc. are the SAME. The cost to build a small block and big block are also about the same. That leaves very little difference in the build......
