Toying with throwing an Iron Duke into my roadster. For the guys who have them, would I be disappointed with power in a light roadster? I have a 283 set aside which I will use in another project so it is not wasted. Running a '40 rear, 3.78, 29.5" dia. rear tires, and a '39 trans, Ford gears. Car weight is around 1'800 lbs. I have a beautiful vintage two piece adapter to put the baby Chevy in there. I'm thinking a decent cam, header, and twin '94's to wake it up a bit. Just don't want a total pooch on the highway. There's a load of threads on here that talk about the Iron Dukes but they don't touch on how well they run too much.
