Here's what I'm looking for.
1) how likely is it to aim for 500 rwhp?
2) This 1970 Mustang Sportsroof has to be able to rip a 2000 Dodge Viper ACR edition(460 hp)
3) Any ideas for a good setup?
4) Want the classic rumbling idle
5) Good 1/4 mile time
6) What size carb would be needed?

Taking on a Viper is ambitious! Like Andre said, probably a stroker crank, big cam & comp up around 11, CHI heads, ect.

I think the stroker engine is key to making that kind of power easily.
You could get there without it, but it would tough on the street.

Do the 393 stroker kit, use either the 1970-71 Quench heads or the CHI aluminum pieces, and with a 3,000 stall and 3.91 + gears you should have a rocket.
Less Carb is better on cleveland I have found, I used a 650 double pumper on my 73 Coupe (12.2 sec 1/4 car). I tried a 750 Vacuum Secondary also and it just didn't perform nearly as well.
