[99 to Life]

slam, I haven't had knockin but I get starting issues when it is really hot out. I've since put a phenolic spacer on my carb and insulated my fuel lines, and it has really helped. Also I run high test gas and it has really helped. I def think there are air flow issues and have thought that since day one. I'd try insulating your fuel lines, run the spacer (not aluminum) and try that out. I've thought of some louvers for the side of my hood, but not on top, would rather not if I don't have too. I actually don't run the rubber hood trim so I do have a little gap where the hood meets the fender, so that might help some. I'd say if you temp is below 200 deg it wouldn't be so much of a timing issue. Could maybe try different temp spark plugs. My temps are about 190 or so on a really hot day, I'm usually around 180 I'd say. I see you have lots of aluminum and chrome stuff in your bay, all of which is just soaking in heat. I'd say the biggest key is keeping the fuel cool first, aside from timing to your cam specs. oh lastly, I think they make heat shields that go under your air cleaner, that way all that hot air isn't going right back into your cleaner. Plus gas today is just filled with ethanol, I'd run the better stuff because your compression might be on the higher side. one last thing I'm doing this summer is wrapping my headers, for sure.
