65 dart small block
A .513" lift cam? Any particular reasoning behind this particular number? There's no real reason to go past about .480 with a stock 360 head, unless you want to replace the entire valvetrain. Keep it simple and use something like a Comp XE268. Save your money for headers if you plan to run them, you'll spend plenty on an early A-Body. Cheap, big cams, and stock compression usually don't add up to screaming performance.
Then there's a new transmission with a GOOD converter, a new rear axle... the list goes on.
I agree with Chief, unless you plan on drag racing the car,
in the 1/8th mile class, with 5:13 gears, I would stay away from that cam.
For Street use, I suggest choose the cam you want, along with what rear
gear ratio you want to use.
If you want to go 3:23 to 3:55 ratio, so you can drive the car on the highway,
and still get some sort of fuel mileage, you choice of cam,
will be less, than if you want 3:90 gears, and don't care about fuel mileage.
Here is the biggest cam I would choose, for street useage, ( I would use 3:55 gears with this cam)
don't forget you will need new, correct strength
valve springs that match the cam. ;)

For 3:23 gear I would go with the next smaller cam, by Lunati.
