-NHRA 8.50 cert cage. 1 & 5/8 mild steel. Has door bars but you canâ€™t swing them out you have to just unbolt and take out. I take them out for street driving.
-Truck has been 9.706 at 139.69mph. Non-intercooled with E-85 on a 1.543 60ft leaving off of 5lbs at 3800rpm and it has been 1.4s to the 60, the suspension just needs dialed better.That was before the upgrade to 160 injectors and 2nd fuel pump because last year I ran out of pump.
-Truck weighed 3950 with me and a full 15-gallon fuel cell. But has since had some weight reduction done and havenâ€™t reweighed.
-Super clean truck but does have a few scratches and paint imperfections, it was repainted in 1982. I replaced the floors and cab supports when I built it. Dash has some cracks and door panels have some wear and have been notched for door bars. I street drive it a lot and it does very well.
