Well, just so you're aware...at shows, I almost ALWAYS pass up the 351W/Wstroker converted cars for wicked 8.2 based motors. That's a personal thing...and mostly it's because I like beating UP on the Windsor and Windsor strokers with an early car and a 306/347 combo (my current motor is a 306...and believe me, I had options). Dropping a Windsor into an early car just seems like the 'easy' way out, and not even the most efficient easy way out to boot. Why not build a monster 347 for it? The car will be more balanced, just as reliable, and I can guarantee you, faster, than a comparable 351W. If you're worried about the block, use a Boss block and go with a big bore 363. The price is right, and the durability is there for sure.
It might cost a little more, but the 'cool' factor will be doubled, as will the performance. A 347/363 in an 8.2 deck block is a thing worthy of respect, and just a tiny bit of fear. They flat out fuggin MOVE. A run of the mill 9.5 deck stroker, in my opinion, pales in comparison.
Good luck though, whichever way you choose to go. And if you decide to sell that thing for a reasonable price, lemme know =p.
~These are just some of the drawbacks we...as guys who like to go mach 10 with our hair on fire and these little motors screaming at rpms that make other guys cry...have to deal with.~
