Welcome to CHR!

I really like Ryan’s idea about Tilden Motorsports Ready to Run Engine Package 5.3L. For $2500 you get something that’s already clean and nearly bolt in with all the computer and run-ready components in place and will in all likelihood satisfy the authority having jurisdiction concerning the emissions controls as it is a stock-type replacement. They also have transmissions. With Gilroy only 200 miles away, I’d be tempted to give them a call and then go see them and talk about what you’ve got and see what they can do as far as supplying a complete engine/transmission combination.

That said, a 5.3 will fall about 100 horsepower short of the 5.0 Coyote Mustang GT so you’ll not likely surprise a new generation that sprints 0-60 in the low 4 second range but you will have a dependable power plant that gives respectable performance for many more years and not break the bank at the pumps.

Have fun with this car – nice wheels and tires and a lowered stance turn these into boulevard bruisers and still offer seating for the family to take a comfortable drive.

Again, welcome and keep us up to date,
Glenn
