Carb for 408

Go on Facebook and look up dominicthumper and get him to do a carb for you.

Or mark Whitener.

Or BLP. Or Braswell. Or Dale Cubic. Or Dambest (I forget his name).

If you buy a carb from one of theses guys you most likely won't even change a jet. If you buy an off the shelf carb, you WILL have to tune it. It's a pay now, pay later deal.
Braswell is SERIOUSLY overpriced....Just my opinion as someone who likes to keep a few dollars for other things.....
