Last night, while crawling around under my "new" '66 SS (trying to get the bleepin' starter bracket bolt off the block!) I noticed an equalizer pipe welded between the two 2 1/2" header pipes.

I'm interested in the pros and cons of this crossover. I think it helps to explain why the doggone thing runs so quiet with it's 3-chamber Flowmasters compared to the awesome rumble of my 2-chamber FM's on my '70 SS (which I love by the way). Does this really improve low-end torque? Or is it redundant with the crossover in the intake or what? I kind of hate to remove it and weld in new pipe since the exhaust is very new aluminized and looks gorgeous, now.

Thanks in advance.

I would say leave it there. As for improving low end torque, i don't know, i've never had one but i've thought about putting in a crossover before. One of the cons for me is that it does muffle the rumble of the exhaust, the pulses won't be as loud. As for pro's, I can't really give you any because I don't know enough about them but they are there because otherwise no one would use them.

check out this previous post. I asked the same question not too long ago. http://www.chevelles.com/forum/Forum1/HTML/002371.html Trent

Thanks, Trent. Some interesting responses, particularly the ones relating to pulling the tranny - which I have to do!! Darn.
