318/360 heads,with thumper cam

As for the torque convertor deal,i was planning a 4 speed swap,as theyre all over craigslist,as cheap as 200$,so i dont want to have to spend any money on my 904 i have now.thanks everyone,let me know about what intake would be the best for my app...

As far as the Eddy you might as well step up to the RPM air gap. That manifold works well on anything, you could keep it so long you could will it to your grand children. If the M1 is the dual plane that good manifold and a good deal at that price. I would personally stay away from the Torker for your current application.
