Lets have some fun!

If you have Edelbrock Performer intake and not Performer Rpm theres one problem. The performer cuts your rpm to 5500, 340 can handle 6500-6900rpm. If you have stock high compression pistons all you need is J or X heads ported, headers (dougs are great, i have heard) good cam and edelbrock rpm or rpm air gap intake to get you close to 400hp or so. Is that enough, thats your decision...
