Too; pretty much any non Lean Burn TQ will work on a stock 400, even the 1980's 360 V8 applications.valiant67 said:Yes, that would work. You can make the carb on there work, but that's a lot more hassle than replacing it in my opinion. The earlier 400 Thermoquad is probably tuned for a little more stout engine than yours but I'd bet it will fine.
