97 GT pi swap time or junk it?

Okay so I bought this car as a project. Paid $1500 with 112K miles on it. Originality the guy didn't want to fix the intake manifold leak so he sold it to me. I fixed it up and got it running for a couple months until recently I figured the Head Gaskets are bad. Took it down to my mechanic and got a Compression test and it came out good but coolant is getting into the Combustions? As in the Heads could warped, bad, or the gaskets and he doesn't want to jump into it. Told me to junk the car or buy a rebuild motor for it. What y'all think? Is it worth keep going or just get a different motor?

It'll be a month or two project but was just wondering if it's worth keeping. Bottom end is good, just heads may be warped and need head gaskets. Call a few shops and all said around 1300-1600 bucks to fix. Figured either pi swap or pull a motor from a salvage car.

This one I just bought. Kinda a project car. I like the look and it will complement my two others. The only other issue will be the exhaust. I think you scored better than me!! I'd go for it..

A year or two ago y mechanic back at my parents house said it would be 1800$ to put a 4.6 including labor with about 60k on it into my car if something even went wrong. There's so many, that they are dirt cheap. I would tell them to hook up a pi 4.6 and call it good for couple hundred bucks extra. Have a nicer newer engine and a faster one

If the rest of the car is in really good shape which it looks like it is. Grab a PI motor from the JY and swap it in. Get one out of an 02-05 Explorer if you can so you get the WAP block.

You paid next to nothing for the car so even at like $1500 to get it running again you could still get your money out of it. You could also just have bad valve stem seals but you might as well PI swap it regardless. I mean if you didn't want to do the motor just get some PI heads/cams and a new PI intake. PI swap cars are actually a little faster than PI cars or a car like mine that has a whole PI motor dropped into it since you get a pretty solid compression bump putting PI heads onto a NPI shortblock.

And as far as parting it... hell I see nearly $1500 right in that pic. Wheels/tires for $600 if they are good, hood for $300-$400, front bumper for $200 if its in good shape. I'm assuming the driveline is fine besides the motor and if its a black interior there is another $400-$600 for just the interior. That's not even getting into the small nit stuff that ppl will pay for.

PI swap it and let it live! you can pick up a perfect PI engine for under $500. if you want to do the work yourself it's almost a direct swap.

I don't wanna see another decent SN95 junked

Performance Improved. On the 99 GTs Ford redesigned the 4.6 modular heads and bumped the horsepower from 220 to 260. They called them the Performance Improved heads.

The heads themselves may have been placed on another car before the GT, but that's all I can remember about them.

The car has a new paint job with a few rock chips. It's bone stock to the ford exhaust lol. Has the FR500 rims with new tires. The interior is black and grey but previous owner replace the grey seats with black leather seats out of 01 Mustang. I've been looking around on eBay and craigslist for either a motor or pi heads and hardly found anything. eBay wants at least 1500 for a motor. When I have a day off I will go to the JunkYard and see what they got.

Nah PI is just the name assigned to the updated heads from Ford.

The various "stages" of heads refers the the amount of porting and polishing that has been done to them

Do what Scotty said, find a junkyard motor 01-04. I installed one in my old 96gt and had zero issues. I had to make a very small mod on the coil pack brackets but it looked like it belonged. You won't regret it, more power and better sounding exhaust.

My 98 has a 99 motor in it. Drops right in and the stock tune on the NPI is fine. Any 99-04 will do it.

97 GT pi swap time or junk it?

Yeah. Think I could get anything from the old motor after swapping

Edited. Also after swapping motor do I need to convert to the coils on top or can I retain the coils I have now?

Found an 2004 crown Vic motor with low miles and for a good price. Swapping should fit my 97? Should I worry about the 6-8 bolt crank or no?
