Ok, thanks for replying. The pump I bought is a FWB block, I don't know if it allready has the correct valves for automotive use. Externally the only difference is the absence of the front dynamo mounting that I will have to weld as you did. I hope my engine is 1460cc (FWB crank and rods) and not 1020cc but I have to check this, I don't know if an FWB casting automatically implies 1460cc.
From what i've read, the pumps were mostly 1020cc even with the FWB casting. Just take the head off and measure, if the bore is 3" you've got a 1460 motor.
I am converting a FWB pump to automotive use. What did you do to the head exactly? Did you weld a plate to the front to accomodate the upper front dynamo mounting?
I did have a plate welded to the front of the head. I also had my machine shop shave the head 040" and install larger exhaust valves. At one time i had two spare heads and was going to have on machined down 060" just to see if it could be done. The only other thing i did was slightly enlarge the ports and smooth out the rough casting spot in the ports.
