I have one on my 75 F250. 351M, T18 four speed, dana 60 with 3.73s. I love it. Runs great, gets incredible mileage for what it's in and zero bog. Yes it sounds like a Thermoquad.
Planning on finishing Route 66 this Sept from Chicago to Kansas where we started last fall going West. We were going to do it this May but the weather was terrible so we pushed it back to fall. Hope you'll follow us
