Is it toward the front, rear or all around?

Most likely the timing chain guide if it still runs fine.

But, it could be anything. There are a lot of components up high in a mod motor.

Waiting to see what it is first but if its too bad it would make a great project car to put a new motor in bigger and blown.

I'm pretty sure a follower can be loose or fall out . :dunno:
It can fall off in which it would make no noise.
But it would not be loose unless there was an oiling problem and the lifter didnt pump up.

OP's car is fucked. :pedobear:

Definitely bottom end. That motor is fucked.
Put a shovel and bag of cat litter in the trunk and the title in the console.
That way when it decides to put the insides on the outside you can clean all the parts up with the shovel and place them in the trunk (in case the new owner wants them), spread some cat litter to soak up the oil off of the highway and sign/leave the title in the car when your ride shows up.

Yes. Same block and heads

See if you can find an Aviator motor. They come with a 3 bolt tensioner (timing cover) and revised heads

+1 on the Aviator motor.. Try to search junkyards for a totaled one. As soon as anyone tags an item with mustang or cobra, for some reason the price doubles.

When I was looking, I found it best to look through local channels. Junk yards have a network that they work through and usually can find anything you need within a 100 mile radius.

You still need to swap your front dress over the the new engine. I wouldn't use the aviator cover.

Aviator engine works just fine here. Yes you will need to reuse your top end.

I put about 5,000 miles on my barn find Aviator engine with around 100,000 miles when when I got it. It works fine.

If you go this route, be sure to put in new plugs and ESPECIALLY C.O.P.S.. You don't want it misfiring over something so minimal.
