Im putting a 5.3 in my 3rd gen toyota pickup, and the best solution I have found to getting the motor as low as possible, while keeping the exhaust manageable is flipping my C6 manifolds upside down (much like the turbo guys do), and switching them side to side. Yes the front of the frame will be fabricated to allow more uptravel with links, but widening the frame at the motor while it necks back down to meet the factory frame at the firewall is something I would rather not do.
My concerns are as follows:
Heat soak from the manifolds being flipped affecting performance and possibly affecting the factory fuel rails by letting them absorb too much heat via convection. I know I have seen plenty of fabricated headers going up and over the intake manifold (much more severe than this setup), but I never read any of the issues faced performance wise and parts wise when doing this.
Also, I am worried about heat conduction on the factory plug wires, and possibly having to relocate the coil packs due to their proximity to the flipped manifolds. I will most definitely run sleeves over the wires to keep them from melting all to hell, but If i don't have to relocate the coil packs I would rather not.
So in a nutshell....has anyone here done this and what issues did you encounter. What preventative measures did you take to deal with these issues?
Am I making a big deal out of nothing?
