Just to correct some 411....
Motors with better rod ratios WILL make more torque due to more time spent at TDC and less friction losses to the piston/cylinder wall angle. They WILL handle higher compression better than the low ratio motor(302 and most strokers)
Strokers make more power due to more CI (inches are everything) and the use of the longer lever(stroke). They suffer from higher piston speed and friction/reliability issues caused by (relatively) poor piston/bore angles. Blowby is increased....seal is decreased. For a street application strokers will not last as long as a COMPARABLY built high ratio motor. That's why they build bulletproof strokers....they need to be that way. Any motor needs to be built for the ponys it's making! For the most part this is philosophy...most strokers aren't going to need to see 100k. The stock 351 has a much better rod ratio than a 302. It will also take money to convert that mustang. If you are worried about long term durability the 351 is better than a 347 stroker...how much? Too many variables to say, but apples to oranges the 351 WILL last longer. The longest ratio you can have in ANY application is desirable whether it's stock, stroker or long rod motor...stroker builders spend alot of time trying to get the best ratio out of their combinations. A racer planning a rebuild every season just doesn't care.
