that is a short wheel base. you will have a squirrel on your hands here.
engine hight is lower is better., a crank hite of 10-101/2 inches is typical in full tube cars. This will give you 2 - 2 1/2 inch clearance with an 8" oil pan.
If it is going to see any street duty at all, you will need to be higher.
I would recomend a set of wheelie bars for the back.
