well to solve the wheeling problem I was thinking of making a longer chassis or having one made. My hopes are to have this keep the front end doun and improve high speed handling.

for two separate engines making seprate loads is true but why does it matter. if I have lets say 1lb of torque of one engine and .5lb of torque off the other then I will simply have 1.5lb of torque..... I think. As for one reving higher than the other... well I guess I just wont get as much top speed as before. due to lets say the stock engine reved higher than my additional engine. then when I reach top speed the additional engin will be holding the stock engine back.... I think. My solution is to gear the car higher and take advantage of all the additional torque I have added.
