RE: [Classic Mustang] Re: 65 mustang speed issue...

Jim, I believe the purpose of the heat riser was to have the exhaust gases backup through the intake manifold and through the cross over, and thereby warming up the carb faster.  The heat riser had a bi-metallic spring in it and would gradually open with exhaust heat temp.  Phil

Walt,
     Yeah, I kinda' thought there might only be one heat riser (I "think" on the passenger side). Two would make it really hard to get the exhaust out. I suppose the factory has their reasons (especially in colder climates), but to me, it just don't make sense to ever block the exhaust, especially no better than stock manifolds flow anyway. I guess that's why "they" get the big bucks, and "we" get to modify them to work right...LOL. I bet a lot of people would like to have California weather. I know I would, even though NC weather isn't usually that bad. With a little fancy footwork, I can get by without a choke too...LOL. Have a good one.
