They are CNC'ed and we custom build everything in house. The chambers and exhaust side are hand polished for final finish. Highest quality craftsmanship you will find anywhere! :cool-smiley-027:

Have you done any with iron heads ( Darts ??) ?

All these pic's are making me re-thinking
my "2 more years" plan:D

I really don't want to take any more weight out of the
back of the boat. (c.g. issues)
When your ready let me know. I would use the Dart Iron Eagle if you would like to stay with iron. I have another set of 575's in the shop right now which are getting Dart Pro 1's, whipple coolers, cams, pistons, oiling upgrades, ...ect.

mrhorsepower, what do you do with the fuel system after the builds? Remap? Add fuel pressure? Any different components?
