I am looking to get away from superchargers an looking to go NA, I dont know what to look for in a NA engine to make big power. I been looking at the Tunnel ram post in the general discussion section. Thats the kind of motor I'm looking for.

I have a 502 .30 over to work with. I would like to see if I could get some where around 680+ HP out of it if possible. I want it to run on 93 octane so lets look to run some higher compression. I would like to use is a duel 4 barrel high rise tunnel ram intake

I have no idea of what heads to use, I would like something I dont have to send out and get ported.

I am not sure what tunnel ram to use, I here the Dart setup runs well. And what about carbs, I was thinking of two 650 double pumpers , Any suggestions.

The cam will have to be custom made. But do I go with solid or hydraulic roller??
