Broken Timing chain

Ok. I just purchased an 03 Black MM with 125K. One of my best friends bought the car brand new, and she decided to finally sell it to me. Unfortunately it has a broken timing chain on the driver side as a result of the tensioner going bad, and she doesn't have the funds to get it repaired. So It is now sitting in my garage. :) I have not started taking the engine out or appart yet, but her mechanic said that one of the cams will not rotate and that he suspects there are some bent valves. Here is my question. What to do? If just the valves are damaged? what to do if the pistons are as well? I have a budget of $5,000 for the rebuild, and want to go as quick as possible. The car has 4.10's, a chip(unknown manufacturer), Cat delete pipes, flowmasters, and a Zex 75hp dry nitrous kit. It went 12.89 on drag radials. Otherwise stock. I am most likely going to remove the Zex kit to sell it and apply it to a bigger wet kit. I am a nitrous guy. I had a 97 Cobra that i Put a ATI Procharger with intercooler on and just wasn't happy with it, so I'm going to stick with Nitrous which Ive been using since I was a teenager, and am very confident in tuning. So I would like opinions on what mods and upgrades are out there and what really works coming from the folks who use them not what the company says they do to sell them. Thanks in advance for all of your advice. :)
 
If there is any binding, just pull the engine and replace it with a used one. Its probably the cheapest and most sensible route.
 
I thought our engines weren't interference fit. If true, there is no way valves, or pistons would be damaged by a timing chain failure.
 
I have a marauder engine in my Mach 1 and I may be getting rid of it in the next month or so. It's stock except for the 96-98 cobra itnake cams that are installed at Marauder friendly LCs of 107/112.

There are many options and having to spend almost 7k isn't a good one. JDM has a forged stroker shortblock w/aluminum block block for $2999 and you can get your heads done for less than $1k. Add gaskets, bolts and oil pump and your still less than $5k. The stroker will add a good amount of torque which is just what the Marauder needs.

That is a damm good deal there pretty hard to beat that HOWEVER.....

If you are paying for the work IMHO the complete engine will end up costing less.

The Aluminator is still a "Production" engine while the JDM unit is custom assembled so it should be a tougher piece by a long shot...
 
I fixed this problem for about $500 but if the timing chain broke there is more then likly an oil preasher problem that locked up one of the cams. Meaning there's more damadge you are going to find a little later (5000 to 10000 miles later). Ask me how I know!
 
Dang. That JDM stroker short block is very tempting. Anybody know of any real world numbers on HP and Torque increase with the rest of the stock components? Has anybody played around with afermarket cam shafts? "NA SVT" could you please PM me about your engine that may be coming up for sale? I will have mine removed and disassembled well before a month. :)

I'm with Joe, this looks like a deal and a half.
