Performance difference: 351W vs 354 stroker?

Been playing with the Dektop Dyno,did not have all the cam specs I needed,but most,kinda winged it on the rest,ran your engine with open headers,I do not have a scanner (actually I do,just do not know how to use it),so I'll give you a rundown of what I came up with..... As I said early,you have one hell of a motor,can't wait to take a ride,the Desktop Dyno says your set-up tops out at 464 hp @ 6500 rpms,torque is 431 @ 5000 rpms.....pretty damn good I think,I have found this to be within 8% of actual motors that were actually dynoed,some less,but the most off was 8% and the Desktop Dyno is usually over the actual dyn #s....I'll bring the prinout to NPR for you.....

Now the bad news (not really bad)I ran the same set-up,but using the stock 351-W bore/stroke,results were the 351-W put out one less hp @ 6500 rpms,came in @ 463 hp,torque was 2 foot pounds less @ the same rpms (5000)....Suprised the heck out of me,I thought the 351-W would do better and at a lower rpm,boy was I wrong,would love to see similar actual dyno #s on a Windsor and a stroker like yours.....
