WOW!
Welcome to the forum. Good info.
My build is a ratrod 49 Jimmie PU with a 84 corvette Xfire against aTH400.
20k original miles on the engine. Using original TBI.
Could not find an original harness or ECM so went with the 1227747.
Not on the road yet but still working on the running gear and body.
Will a WBO2 help with the gasahol stoich problem?
