Time to think out side the box. Too many smart people have made this car possible. Now for a suggestion from a certified idiot. Take the entire rear engine out of the car. Engine, tranny rear ballast if any. Get the car as light as possible. Retain the 4wd by way of same shaft system that connects current power plants together. Hire a NHRA TFD tuner, Like Alan Johnson perhaps.Use a top fuel clutch that he would be very familiar with. Now start off small, feeding the NITRO to it. With less weight, less chance of breakage, complete spare engine ready to go and more then enough power available with a Whipple on NITRO. Why do I think more then enough power. I have read many times that Tom Burkland's car was only at 40% throttle at 450 mph. It runs old Donovan's on alky and if memory serves were so mild of engines that the torque and power curve both peaked out at about 5250 rpm. Going to a 4 speed might be necessary but beyond that it should at least start going up in the BURKLAND SPEED RANGE WITH OUT ALL THE BREAKAGE. If there is any advantage to the Au. track it might get in the high 400's. Might not be 550, but at least it would be a wheel driven record. Smart people, jump in......
