That is what life is all about.........have fun do what you want to do with your Challenger and have fun.

Do the best you can within your means and don't get too caught up and find yourself in a rabbit hole.

Seriously though if your wanting to run a small block why not put a small turbo on it. There is a small block turbo setup on the for sale section in Michigan that a member had on his Valiant if I recall correctly.

Get 318 mpg until you add some pressure to it and then get the added power. It's cheaper than trying to build a stroker engine and might be an option for your project.
