Suspension question

I have 1970 Plymouth Barracuda w/ a 440 and it seems very low to the ground it is supposed to be a 318 car so just wondering if the front engine cradle is wrong and maybe too much weight in the front end can anyone give me some ideas of how far off the ground it should be from the cradle to the ground, can't even get my floor jack under it.
