drive shaft angles

[markie]

hi guys, if the diff sits higher than the trans (as in a rat rod setup) how do you arrange your pinion angles to suit. thanks guys

The pinions angles should essentially remain the same, albeit reversed. Rather than the shaft dropping to the diff, it'd be the other way around, The total angle would remain the same though.

In regards to engine position, the LVV standards state:
"(a) in the case of a modified production vehicle, duplicates as closely as
possible the original engine crankshaft centre-line, ensuring that the
drive-shaft universal angles of the new drive-train match the original as
closely as possible; or
(b) in the case of a scratch-built vehicle, is correctly aligned with the driveshaft
and differential.

Yours being a rat rod, would probably be a scratch built, so the key would be to ensure you meet the requirements of section
2.5(8) of the standards here: www.lvvta.org.nz/documents/standards/LVVTA_STD_Engine_&_Drive-train_Conversions.pdf

Keep in mind generally, drive-shaft manufacturers recommend operational angularity of not less than 1 degree, and
not more than 5 degrees.

Hope this helps.
