Just found out that the engine in my sons 96 GT has a cracked head. For the cost/time involved in repairing it, would we be better off replacing the entire engine? If so, would one from a 99-04 be the best way to go instead of going back with a 96-98 one?

If anyone has gone this route, what all would we need to complete the swap?

Thanks

 

I got all the parts to do a Pi headswap if you want em. Pi heads,lower and upper intake with injectors and fuel rails. All you need is a pair of Windsor valve covers. 400 bucks. And this swap is good for over 50 hp and adds compression too.

 

Anyone know this answer? What is needed if a '99 or '00 4.6L is used in a '96-'98 Mustang? I think the compression ratios are different. Any reprogramming needed?
