It's nothing to special, it a 318. White bucket seats, front disc and a 7.25 rear end.

OOPS missed the 7 1/4 rear diff part. Does not change anything except you still need a diff. 8.8 Fords are an affordable easy swap and gives you rear discs.

Didn't the V8 cars in 70 get 8 3/4 axles?
What's the 5th digit of your VIN? Should be G if its a 318 car.
How do the grille and dash look?
