man, there are so many variables, and it would depend on the motor, and heads, the list goes on, I would think if you have the right set up that needed the 1 7/8, ie the 1 3/4 was choaking the motor, you could see at least a .10th.

Need a little more information! 
If it's a stock internal car and you switch, probably none, might even get worse. If it's a 427" mill, you might be a *slight* bit quicker, but not much.
In any case, changing the air pressue in your tires will have a greater affect than switching to 1-7/8" headers.

I've have a 408 w/ all forged internals. Mostly will be running all motor but might spray when I'm feeling naughty 
I'm just trying to get an idea if ANYONE has experienced gains in the 1/4 mile (not interested in dyno queen numbers) when going from 1 3/4 to 1 7/8.
To me, its not worth spending 1k+ just to pick up a tenth. 3 tenths, maybe.
Thanks
