66' Barracuda and 273 with headers

Good luck.
Keep us posted on that 400 horse. That's almost a 1 1/2 hp/cube. Nascar engines make 2hp/cu.in so the engine shop has a lot of work cut out for them. It might be a push to be street able. Just say'in.

Yes I know. They are squaring up the block so every bore is exactly square to the crank, line boring this and cam boring that. Balancing everything to the smallest amount. Heads are getting treatment with a CNC machine program from some MoPar engine builder in the mid-west. It is quite the process when you physically see how out of square these blocks really are. Friction is a very dirty word. I'm excited to see this thing on the dyno!
It will be like a lawnmower on steroids! I've always built my own engines with machine shop help. This is the first time I've walked in laid down cash and said, " This is what I want, can you make it happen?" They Said "YES!"
Anything north of 300-325 hp I am ticked pink.
