340 Stroker mainly for street, what gear would you run?
As you probably know a 3:55 will be a little bit quicker through the gears a little but a 323 will have a better top end and fuel economy if that matters.They're both great Street ratios especially with the stroker combo but a 323 will get you a bigger ticket LOL if it's going to be a around town cruiser I'd go with the 355s if you're going to take it down the highway regularly I would be looking at the 323s real seriously.
