Sparky, the only problem the car has is a partnership problem. Now that Chet is gone nothing has changed, his part has gone to Doug & he has what appears to be another failing partnership in another liner project.
The car has never had big block Chevy engines in it. They are 525 inch Rodeck's with special high port heads. It was initially built with dominator carbs but in 91 when I started working on it, we changed it over to Hilborn units & also stretched it to accommodate the 7 speed B&J's. The Rodeck's made just over 1500hp each on the dyno at that time.
Steelman, the only real advantage to counter-rotating engines is that the chassis won't torque load one side & if you dont have machining capabilities you might not want to go there.
If you are in my neck of the woods, you are welcome to come & check out my liner build. It's a real low budget 4WD car, using lots off the shelf & junk yard parts. It's 35" wide, 31" tall & 43ft long, built to accommodate two engines but I only have one 605 inch turbo'd KB600 in there now. I'm in SE Idaho about 45 miles north of the Utah state line.
