There were two of something Taylor just like that at our Ceasers Creek meet last year. One was an I/O with a 350 and the other was a sleeper Jet with some nasty Big chevy type plant. I can only say that the jet was an a$$ kicker and the I/O would do somewhere between 55 and 60 with two people. running next to us. I'm pretty sure the guy with the jet is on these boards.
