I have a 1938 stock flathead.It was rebuilt back to stock.I am putting an original Eldelbrock Slingshot manifold on it.I am not sure of the best carbs to put on it? What size jets? Any help would be appriciated.
Bill,
I have a complete 33-34 stock rear end with 411's.Also have a complete front end.
What are you building.I have some truck sheetmetal parts.(front fenders,cowl,grill and misc pieces)
Thank you for responding.I just started to take the rear end apart tonight.I will look to see if the 9-39 is stamped on the r/p.I just bought a set of 3.54 gears.My next project is to attemp to switch the gears.Any suggestions?
Thank for all the input.I just wanted to find out what it was before I took them apart.I have 4.11 in my roadster pick up know.I think I am going to install a set of 3.54 in it.When I take it apart I will let you know what I find.
The rearend is out of a truck.BAsed on your information it is either a 33 or 34.I just tried countinh the revolutions. I think it either a 4-11 or 4-33.Maybe the 3-4 that is marked in the rib indicates 4-33's.
