Title: water lines?
Post by: 88CARRERA on May 31, 2010, 11:23:44 AM

are my lines correct?
from jet then "t" off to front of each exhaust log
then back of exhaust log to intake
then front of block back into logs?
is this right.
my new tunnel ram has only one fitting on the front. and no cross over in the rear

With the long bolt manifolds you show in that pic, it should go like this:

From pump to T, T into lower port on front of log
From upper port on front of log to engine "in"
From T-stat housing to snails

Simple as a pimple

It uses the exhaust log as sort of a "pre-heater" and makes the logs the coolest part of the engine so you don't burn yourself....
