Putting together my 62 Lark with a 327 slowly but surely. I've read some posts on clearance issues with the chevy mechanical fuel pump to frame. My entire drive train is installed and buttoned down and looking at installing the fuel pump I will have about 1/4" clearance at the closest point to the frame. Is that enough space? I'm not going to remove the engine to bang the frame, so my only alternative would be an electric pump, but I prefer to stay with the mechanical pump. Thanks.
