Intake manifold choices
Going with the concept of skinning the right cat before spending big time and effort...
Get some termperature stickers or pens and see if you can figure out where the fuel is getting heated. Mcmaster, Omega, or Pegasus Racing are three different types of places that carry that type of stuff. Contact type thermometers, or even IR may be useful. But need to learn how they work and do some calibration experiments (ice water bath, and boiling water are common ways to check if you want real accuracy). The IR works on emissitivty so the type of surface can throw those readings if not taken into account.
If you just need it within 20* then that's overkill.
Only mentioning it because there can be a huge difference in percent of fuel evaporated between 110F and one at 130*F.
On my Barracuda the problem is the headers, even though stainless, are close to the frame rail. I've added insulating sleeve and zircotech 'foil'. The whole engine bay can get pretty hot after coming to crawl in Frisday night rush hour after running for hours on the interstate. Hot enough to soften the nylon gaskets on the fuel bowl inlets.
Lesson learned. That's a story for another time, although I'm sure I've posted it some time in the past.
