I had Lenny build a 8" converter for my 408 after I killed my 9.5" $450 Edge racing Converter. It never 60' within .1 of the Edge and .2 in the 1/8. After building and dynoing my 434 I called Lenny and talked about my converter. He said it should be good, so I tried it, 18% slip in the 1/8. So I call him back and he says it's to loose and to send it back. He tightened it up 500 rpms (at almost $275) 5100 from 5600.

I ran a best of 1.38 several times with the 408 and a $450 9.5" Edge converter. After adding 100+ HP and probably that much torgue, plus spending over $1500 on a converter from Ultimate I have ran a best 60' of 1.44.

I'll look elsewhere for my converters.
