Duttweiler built 388 cu Bowtie block with twin 66 B.B turbo's in a 86 GN. This drivetrain is sick!!!! My (street car) GN I built from the short block up recently layed down a 10.53 pass at almost 130 mph with a 1.65 60' 
with a lot more in her, I cant even begin to compare the power of the new ride to her!!! This drivetrain is 100% solid with very low use, just needs some engine detailing from sitting around. Some rear susp. mods, and needs to be painted. Original paint, rust-free car with the usual checking, cracked fillers and window/door strips. (will keep me busy this winter)
I cant believe the room under the hood, like this twin turbo Chevy set-up was made for this car!!!! Easier to work on then my 6cyl GN with a/c Lotta going over, and little things, but man this is going to be a sick ride.
Need to do some research on the Motec ECU it currently has, that I might swap out for an XFI. The converter is an Art Carr, that might also get swapped out for one of Dusty's killer converters.
