I finally got that super six setup in. No more vapor lock. Indeed my heat riser valve spring wasn't working like it should on the old one. This replacement exhaust manifold's heat riser valve works great. Now upon hooking this up, my buddy and I were just trying to get it to get me home. And of course, there was major ticking. We knew it was an exhaust leak. When I visit his place the next weekend, we got the ticking to go away. But the difference in sound under the hood was like night and day. It now sounds like I need a muffler under the hood. Mind you, my buddy and I love the sound. It sounds totally cool when punching it. However, it also sounds like a bad muffler up there as well. We know it shouldn't be an exhaust leak, as it is not ticking. And when we accidentally broke a stud when putting on the manifolds, we removed it. Antifreeze shot out, getting some fluid inside the intake manifold. We removed it the best we could. But when I started it up, white steam or smoke came out the tail pipe, but none was under the hood. My buddy, who took this system off his Demon says it is just different to me, and he thinks it sounds fine. Another guy is thinking the same. That the bigger carburetor willl make a difference. Tell me, did any of you guys, after installing a super six setup, hear a lot more noise from under the hood? And I am not talking about when you floor it. Just idling, there is a huge sound difference. The reason I am asking is, when it had the tick tick sound, it wasn't that loud. And we still need to do more tweaking with the timing, and kickdown linkage. Performance wise at this point, is barely noticeble compared to the one barrel. I think the timing will cure most of that though. The main thing, the vapor lock problem I had is officially gone.
