stock to long rod jetting changes?

[jasonsb]

I purchased a long rod crank that I will be putting in soon. Will my carb jetting change and the timing change? I'm asking cause I know that the piston movement may be a little different now...but I'm not sure if it will change with a long rod alone. I know that a stroker may change things, but I'm not sure about a long rod by itself. Right now I'm running 350 mains with the stock crank. Thanks for any help!

You didn't by chance get that off ebay for 172.00 did ya? if so I was bidding on that too.

Your jetting shouldn't change or if it does it will be minor. Actually it would be due more to a different piston size (assuming you're boring as well). I would bump the mains up 1 or 2 sizes and see how it runs. You'll probably end up right back where you are now.
