36/38, which I already had but it was sorta tired I guess. The work they did on the manifold made a big difference. The car is much happier now. We are putting dual Webers on the other car, but this one my son drives to school. I didn't want it to be TOO much fun ya know...;-) Suspension is next. So far we've done the ignition, wheels & tires, Stahl header, ANSA, and this carb & manifold. It's funny, because the day I bought the car he said it was the ugliest thing he had ever seen. Now I can't get him out of it. Another converted soul. ;-)
