You honestly won't know until you have all the weight of the finished vehicle setting on the tires after that first trip down the block and back.

Back in the day when guy were cutting MII front ends out of donor cars and using the whole thing many had to swap out the V8 springs for lighter springs as the weight distribution on a stock V8 MII A stock 75 MII V8 fastback weighed 2800 lbs with 60 % of the weight on the front end = 1680. Curb weight of a 56 3104 is 3360 with 1995 on the front and 1365 on the rear. Still the engine weight is centered several inches to the rear on the truck than it is on the stock MII.
