length of timing belt on 2G, 420A

[Chris Andrews]

I’m looking for some timing belt lengths.  My brother-in-law is building a hybrid mopar engine and requires a timing belt that is about 55” long.  Unfortunately the 1G 4G63 belt is too long.  Using a longer belt with additional idler pulleys to take up the slack is out of the question due to the confines / obstructions in the engine bay.

1G 4G63 DOHC T-belt
length  57.375"
width   1.142"
number of teeth  153
tooth spacing .375"


Does anyone know the length (and the other specs) on a 2G DOHC timing belt.  How about a 420A DOHC timing belt?   Anybody?
