Sorry guys, I know this has been asked before but I'm still fairly confused on this issue. I'm building a 427 side oiler for a cobra kit car. I'm trying to decide which of two dampers to use.

I have what I've been told is a 427 damper, it's big, heavy, has just a line for timing (the timing pointer has marks on it), and has an integrated single belt pulley.

I also have a NOS damper that I'm told is for a 390GT / 428 CJ, the nice thing about it is that it has timing marks up to 30d advanced so I can at least eyeball total timing by interpolating to 38d.

I've read that either will work but I still wonder which is better for a cobra. On the other end of the crank I'll have a 29# steel flywheel. I'd estimate (it's at the machine shop) the 427 damper is maybe 2-3# heavier than the 428 one, it's hard to imagine that doesn't make some sort of difference? If so what difference does it make?

Or should I sell all this old stuff and get a new fluid damper of some kind? If so which one is good, from what I've read the "fluidampner" brand needs machine work to fit an FE, and some of the others the timing marks are off.

Thanks for any and all opinions!
