318 converter behind a 360?

I believe you could just get th B&M flexplate that looks like it has a bite taken out... http://www.jegs.com/i/B&M/130/10239/10002/-1 ... so to speak and not need a the weight...I dont know if it will give you anymore stall but one from a slant 6 will...thats what I have behind behind mine and I get about 400 rpm more stall...puts me at about 2100
