With the "F" cam, you're just wasting your time with the stroker... unless you just want to tow a trailor or something.
Really... what will happen on the street, is the excessive bottom end will blow the tires off from a stop, but the engine will run out of steam in the midrange due to the small cam, and you will be seeing taillights. I outran a 69 Camaro with a 421 small block racing top end on the interstate because of this. He could do burnouts all day long, but just wheezed out in races.
You NEED a cam around 240 degrees @ 0.050" on the intake if you want to come close to your 500hp goal. I don't recall your compression... but if it's 9.5 or less, go with around 234-236, if you've got more, something closer to 240 will fit the bill.
The largest hydraulic roller I see on their website for the Ford is the XE282HR (232 @ 0.050"
, but if you give them a call, they can grind you something a bit larger. They have 236 and 240 roller lobes they can use.

Crane has an aggressive hydraulic roller. It measures 244/256 @ 0.050" with 0.595" lift, and would work well for midrange and top end. It has a 110 degree lobe seperation, which would be great for a carbed application. You can check it out here... But, if I were you, I'd look into something around 236-240 @ 0.050" in the intake.

BUT, you DEFINITELY need to sh*t can the "F" cam. Sell it, and put the money towards the appropriate camshaft. It would be a shame to build that killer engine, only to cut the balls off it by installing a wimpy cam. You NEED the larger cam to let all those inches breathe!
Good Luck!
