Duster engine install w/ TTI's
Test fit on the ground first. I put TTi's in with my 408. There was a molded hump on the block that the headers hit. I had to grind it down a bit. And, even though they asked what kind of starter I had, they hit my high torque mini starter and I had to beat up my shiny new headers to get them to clear.
Then, you need to lay them in the engine bay and start dropping in the motor. You will have to shift everything down as the engine lowers. Kind of a shoehorn fit. I had a few issues with steering hitting and had to shift the motor to clear properly, but I love my TTi's.
