Yes!  I believe it did help some although I think I will need different tires for Elmo than I use for Bonneville.

I made changes on all runs except for the #3 as the #2 run was a waste, the clutch didn't engage for fourth till I had lost my momentom and I only ran 115 mph.  I ran 122 for the first pass with 40* total advance then backed off to 35* and ran 118 on the third pass.  For the second day I bumped the timing back up to 40* and removed the mufflers, I also modified the "Air box" to work with the Mummert intake (the carb position is slightly different than the BT) then ran 126.01 mph.  For the last pass I brought the timing up to 43* total and ran 126.5.  That engine likes timing as did the "Brick".  Also after the first pass I lowered the pressure in the rear tires from 50 psi to 40 psi.

Your truck looked good in Y-Block mag. Looks better in color though.
