it ran straight as a die right out of the box as it happens. we just got lucky with how we set it up. it had an almost stock 390 ford fe, c6 with a 3000 stall tc and a 9" with a spool and 4.11 gears. you could take your ands off the wheel at the big end and brake or floor it and it just ran straight. it would've took much more power for sure before being a handful. i sold it before i ran it much but it did a 12.4 shifting at 5500 as it misfired above that (bad dizzy). i was surprised at how much the mickey t et drags wrinkled when i saw the pics, they were at 15 psi as per suggestions with those. that pressure may have helped with top end stability too. it was a lot of fun and would wheelie on a dirt road :thumbsup:
