Fox VS Vintage?

Thanks for your opinions,

What i was thinking is getting an 65-69 car with either worn out engine, or bad interior and just stripping the interior out to the minimum street safe, and putting about a 400 HP engine in it. I figure this would give me a good car for the track that i can also drive there while im racing high school (must have registration) and also it is good to be different then everyone else out there

PS What do you guys think of this combo to make 400 HP at the Flywheel?

351w:
Bored 0.030 over
10.7:1 Compression
Edelbrock Performer RPM Intake
Edelbrock Performer 750 Carb
New Cam: Not sure what a good duration and lift would be, any ideas? my dad said a little lopy cam would work well?

Also i was planning on getting the engine from a junkyard and doing a rebuild on it, how good are Hypereutectic pistons? are the forged well work the extra $100 if i want reliability? Thanks for all the help guys
