First. There ain't no thing as an easy conversion despite what we think. Each conversion has its own problems and benefits. Second. There is very little weight difference in your two engines. The extra weight of the higher deck height would be roughly 50lbs I would think. They are both small blocks as such, just that one is a "big" SBF. The stroked 351's are a magic combination. Big power with a lot less weight than a real world BBF. If you develop the rest of the car to match the performance of the 427 go for that option. You don't have to use all the extra power all the time but it is nice having it there. Brakes, suspension, chassis, cooling, tires are all going to need serious attention for the power levels you will get. Make a nice driver tho won't it. :-)))
