width difference - B-RB ? - 01/09/18 04:57 PM
can anyone tell me the width difference at the exhaust ports between the B and RB engine ? on my humpback project, the steering shaft runs between the header tubes, and i need to move the #7 tube for extra starter clearance having a 440 with iron heads used as a mock up engine. as it is possible i may use a 400 based engine, i would like to be sure i move the pipe enough so these pipes can be used with both engines. i don't have access to an engine at this time to get a measurement. the pics give some idea of my space i have to play with. thanks guys !
