[Healeys] BJ7 vs BJ8 engine block

[Richard Mayor]

Hi Jon, 

 The blocks are essentially the same.  I believe the BJ7 block has the dipstick in the same location as all of the previous 6 cylinder engines. The BJ8 blocks have the dipstick in a slightly different location but other than that they are the same. Also the BJ8 engines don’t use a mechanical tack drive.
