Extremely Important! TTI Headers were designed to fit with the engines
located to the factory specifications. If the engine is not located correctly in the
chassis, the headers will not fit properly. Use the following dimensions to check
your engine location before installing your headers.
From the center of the crankshaft to the top of the K-frame the correct distance
is 5-1/4". The engine is also off-set toward the passenger-side. Measure from
the center of the crankshaft to each frame rail. The distance should be 2-1/2"
(62-65 B-bodies difference should be 3" and 65-73 C-bodies difference should
be 3-1/2"). If necessary place shims between the insulator assembly and the
K-frame mounting pad to achieve the proper dimensions.
