Maybe be doing a build for a buddy for a hot street car, with the 4-5 times per year to the track. Problem is he wants to an actual 340, since it's an H-code Duster. I haven't been able to budge him on the idea of a 4.00" crank in a 340 block and no one would know...LOL!

So, what 3.31 stroke "streetable" combos are out there and what have they produced on the track?? Converter/gear/weight combos would be most welcome.

Thanks! Oh and Happy New Year!
