Ebay GT45 + 5.9 Magnum + E85 blow thru

How is the hot rod coming along?
Installed my 3.23 SG and new axels and learned by brakes won't work with axels. Bought some 11" drums, waiting for them to arrive. That and the Fitech is still giving me fits when coming off idle. Loads up like its flooding and then it's just a big stuttering mess. Gonna revisit timing and then reset and start from fact defaults again. Sigh...
