-roller rockers

-forged crank
-edelbrock torker 2 intake

I'd really need to know your plans for the heads, eg. full port and polish on the cast iron ones or go for the throat with Aluminum cnc ported Edelrocks. That decision will have to be made when considering your cam specs. cuss there's no point in putting a big assed carb on top if you're necked down at the heads. Also I'd be a little worried about going as high as 13 to 1 unless you're planning on mixing your own fuel. my 2 cents anway but you're off to a good start.
