Stroker or Not
I'm the anti stroker guy on here BUT if you are going to stay with 3.23 gears then I might well lean with the 4 inch stroke.
My 340 has 3.91 gears and 3,000 stall and it runs very strong on the street around here but the 3.91's are holding it back, really wants some 4.30 - 4.56 gears. You can gear for torque but not hp
Just keep in mind gas prices are going cheaper but higher. My 340 with 2.94's would get better mpg I would guess then a stroker with the same gears.
