1975 Swinger 383 Project

Do you think you will be able to put the power from the new engine to the ground? Whats your rear end set up right now? Im about to start researching tires and rims for my car and Im kinda curious how bad the traction issues are going to be.
As of now I have a Ford 8.8 with 373 gears I also have Super Stock leaf springs and Monroe coil over back shocks. I have old school gorilla rims on my car, the tires I have now are 215/65/R15 I’m definitely going to need to go with a fatter tire with the new engine. With the current stock 383 I scratch the tires when I shift from 1st to 2nd to 3rd... that’s if I’m stomping on it. I have a Reverse valve body in my 727 transmission.. and it shifts hard.
