There is a fellow with a Pontiac engine in a truck that installed the manifolds on the opposite sides so the outlets dropped out the front, not the rear. His pipes then ran under the front crossmember but away from all steering. Maybe you could find a manifold with a different outlet location and do something similar. Moving the steering box would be a challenge, you don't want to get into drag link angles or length problems. | | | | | Joined: Feb 2004 Posts: 29,799 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,799 | A set of rear-dump Camaro exhaust manifolds swapped side to side and installed with the outlets pointing up would end up with a front crossover pipe like the old Ford 292's had. Then the exhaust pipe could be plumbed down the passenger's side away from the steering column. Odd-looking, but effective!

I had issues keeping the collector gaskets from burning out. (even with the deadsoft aluminum ones). I would print out some pictures and go to a wrecking yard and just poke around, looking at some different chevy manifolds. As suggested above, maybe swapping them side to side? My 588 2-ton, they ran exhaust out the top of the manifolds, through the inner fenders, and put stacks out the top of the fenders! It was a grain truck used on the farm though and they didn't want to catch the fields on fire. I am sure I would get pulled over if I was driving it around town here that way! | | | | | Joined: Oct 2015 Posts: 94 'Bolter | | 'Bolter Joined: Oct 2015 Posts: 94 | thank you for the replies great information , i will see what i can find in those exhaust manifodles . 1pete1 | | | | | Joined: Jun 2011 Posts: 5,096 Crusing in the Passing Lane | | Crusing in the Passing Lane Joined: Jun 2011 Posts: 5,096 | Engine does not have to be exactly centered, port to starboard.
