Looks like a decent parts list... but you shoulda got the Coyote... If your credit is good you don't need a down payment, just get a nice low interest rate on a 3-5 year loan and then put that money you had saved towards the relatively few mods you need to do to the Coyote to have an 11 second daily that gets 26mpg.
Not to mention I would think long and hard about forging a factory block with a supercharger. A .030 over stock block with forged internals is literally no stronger than the factory shorblock is and will still split right down the middle at the 500hp range. I mean if it had to be rebuilt then whatevs but if you are serious about the engine go with a DART block or go 351 based NA. Nothing is going to make you smile from ear to ear like a well done 408...
I probably sound like an ***... been there and done that... Red flags all over the build list such as MSD ignition stuff, a lot of BBK parts, ported GT40s and then the stock block...

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
