So my son and i found a 53 b3b that has sat in a garage for 42 years,after we got it home of course the motor was froze up (218ci) from sitting so long,after removing the head and getting the motor to turnover we were pretty stoked....well after a new head gasket head bolts fuel pump rebulit carb plugs wires points etc etc...we could not get the ole boy to start not even hit like it wanted to start....after a compression check we have 2 cylinders that are very low. We now are thinking about doing a v8 swap.does anyone make mounts for these cool old trucks? With a v8 swap do you have to cut the firewall? Thanms in advance
