I stopped buy Chuck Lofgrens shop yesterday for help with a trans. We got to talking about his DragPak FS/D Challenger. His car is spotless, both underneath and everywhere else. Just like his one owner 1970 Sixpak Cuda (!)
Chuck put the newly allowed aluminum 6.1 block in the car, and picked up 35 hp.
The old block only made 665 hp, the AL motor made 700! Pretty good gain IMHO.
Now the problem is it carries the front wheels out to past the 60 clocks! His best et to date is 9.55, and he wound up with a class trophy in F Super Stock, entering in SS because he didn't have enough points to run in FS at the Nationals.
Ma Mopar also wants all the DragPack cars at an upcoming event at Route 66 in Joliet, and is paying handsomely to get them there! Nice!
