Crazy is probably the right word. The chain drives between the three engines did not work. The center engine received hell and the chains went into a harmonic at a certain RPM. Today finished converting it to belt drives. The jack shaft is still chain driven. That solved the design blunder. It sure sounds sweet when all the engines are running. Will ride it tomorrow. That 70 Chevelle is a documented LS-6. M-22 trans, 12 bolt 4:10 rear end. It has been a lot of fun street racing it over the years. It is going to be sold soon. The really cool car is on the lift above it.
