426 stroker, is it reliable?

I agree with Moper that there's no way a long stroke engine can last as long as a short stroke version of the same design. Remember the longer the stroke the faster the piston speed is for any given rpm. Also when using the same length rods the piston to rod angle increases compounding the issue. Nevertheless if you drive it sparingly such as I do my car (I only put about 2000-2500 miles a yr on mine) it will last for several yrs. so I wouldn't be afraid to try a 426 stroker.
