Hi!
I´m sure there exist more than this threads about my rooky question. But I did´n found clear answers to my planed setup. 
My 292 is still innocent ... not fresh but in good shape. And I´ll throw out that ugly cross over exaust with the lousy sound and performance. Headers from Reds seem to be the right choice. Also the little intake manifold should replace. I think about a blue thunder from John Mummert with a 500 edelbrock carb.
What do you think about this setup?
Marcel
PS: Used parts and junkjard sessions aren´t possible, because of my location .... GERMANY. Sorry for my english btw.
