I may be able to increase the pulley another 1” max . I don’t have that notched type belt , my v belt is solid . However the belt that I have in there for plan c is now to short, so I’ll be running out for another.
John, if you have time can you give me a dimension below your carbs and frame. Reason, I need about 4 1/2 - 5” to place a compressor their on the cross flow using the same front bracket.
If I don’t hav the room there I’ll try fitting it below the header but on top of water pipe.
If all that fails I won’t use the extended crankshaft on my cross flow.
On another project I polished up a tc bell housing and a few other items . while I was at it I found a faster way to bring out the mirror using 3M Scotch-Brite Roloc Surface Conditioning Disc, and green/ brown rouge’s. These pieces shined up after 400 grit. See before pics . I have a new aluminum sealer that was suggested long ago. My antique van has 4 wheels that really need a makeover.
