Hey I just want to say thank you very much for taking the time to help me out. The noise is def coming from the top. I’m use to 94 95 gt I’ve had a few and this 4v is a entire new ball game for me.If the noise is coming from the front of the engine, I would say timing assembly. It could be an exhaust leak, valves, or something else up up if not. If that noise is coming from the bottom of the engine, you need to have the bottom end rebuilt.
I get a mechanic's stethoscope and listen to everything possible.

I need to grab my earbuds and listen again. That could be possible. The 4.6 loves to blow plugs out of the head if over tightened.It almost sounds like it's trying to spit a spark plug out
Turns out cylinder 2 spark plus blew out and stripped the head, melted the coil which was smacking against the valve cover.
Thanks. I plan on keeping the Mach block. I just figured it would be easier and allow me to continue to drive my car. But yes I do plan on putting a supercharger on the when I build a new motor.Ultimately it’s their shop and their decision.
I choose to save my engine because it only has 33k miles, and it’s the original engine, and my Mach is a very early production 04. Though everyone I talked to in my area told me to replace it I choose to save the engine for pretty much those reasons in the sentence above. Factoring out the prices it would’ve been cheaper to find a replacement, and I’m not even done yet.
A Terminator shortblock would only be beneficial if you decide to boost the car. Terminator’s have stronger internals but have lower compression than the Mach engines, and blocks weigh more. Mach - aluminum block. Terminator - iron block.
IRS adds around 147lbs to the rear end of the car from research I’ve done. Adds more weight to the rear so it feels more stable in corners but isn’t ideal for drag racing. I managed to pick up a complete Terminator IRS for 700. They’re the IRS to get.
Pick your poison.
No cats or o2 censors.You might wanna get the tuned checked out. Haven’t heard very much good about bama. Does the car have cats or a wideband air fuel gauge? Any exhaust leaks?

My plan was build a new engine but keep the pistons an all that stuff stock, just forged. Put in different cams, and get the 9 thread heads and have them ported along with intake, and along with adding a supercharger. Would be nice to see 475 to 500rwhp.
