You make a good point about the heat factor, 427 Street. I am at least 4" from any fiberglass. 6" from any axle components and about 4" of tire clearance. I am using the Sunburst wheels with 255 BFG's on the rear so I have good tire to exhaust pipe clearance. I think I'm OK but I may bond some foil faced DEI insulation in a couple of places just in case. I'm not a fan of wraps.

Wow - 4 inches clearance to the tires! I'm running the same size tire but on a wider rim. With 2-1/2 inch tailpipes I have about 3/4 inch to the tire and 1/2 inch to the trunk box aluminum panel on my ERA. I am going to wrap that section of my pipes. I'm hoping that with the lower operating temperatures at the tailpipes that I won't have the severe metal corrosion issues with the wrapping. The NAF must have narrower spacing between the rear frame rails than an ERA to get that much tire clearance.
