Well, a little update on the 520 deal, it's been a very very long road to get to the this point, but I'm glad to say I finally got the truck down the track with the new engine and almost all the updates on the truck, new rearend with back brace and disk brakes, home fabricated rear suspension, rollbar, trans shield, etc. Still on the to do list: is widen the wheel tubs and reinstall, build a new floor for the box, run second fuel line for fuel system, probably change rear gear, and converter. I made four passes Friday at the street car event at kaukauna wi. First test pass was 11.26 @ 118 short shifting and using two step, second was pass was 10.77 @ 124 leaving against the converter and not short shifting, 3rd pass was after changing from my dambest 980 cfm 4150 flanged carb to my 1150 dominator carb and was rewarded with a 10.56 @ 126, all these passes and only going threw the traps about 5800-5900 rpm with the 4.10 gear and 31.5 tall tire. 4th and final pass I changed to my new drag radials which are only 27.8 tall and about 12" wide, track was cold and I did a huge burnout to break them in but they were probably to hot and the mistress just knocked em off leaving the line, so I pedaled her once and got right back in it and went 10.69 @ 128 despite losing over 2 tenths at the 60 ft, but the shift lite was on before I crossed the finish so it definetly wants more gear. For a first outing on a marginal cold track, on a bunch of new never tested parts I'm fairly happy, there's more in it for sure. Truck weighs about 4100 lbs after all the changes, and it's probably gonna be closer to 4200 after it's finished with me in it, Shes heavy.
