Here's the story...I had one in my car...they built it wrong and it caused me all kinds of issues...but they stood by their warranty...they built me another free of charge and sent it back to me...I like their business..I had one in my small block 340 and it performed great...they sell this one for
17805ST CONVERTER​
10" STREET S-800 TIGHT 67-UP NLU $483.77
I am willing to sell for $350 plus shipping still in the un-opened box...this convertor stalls at 2800 to 3200 in a good torquer 440...​
