Hey everyone, I was wondering, if i was to buy a new motor ,what should i buy? I know that is a broad statement, but i lack in mechanical knowledge. My buddy just bought a new 302 for his 95 gt. It is extremely fast, i am just wondering of a site that could show some info, about this for my 97 GT. Thanks everyone!

For money and simplicity reasons, I would go with a 98 motor at the newest. The ECU and ignition on the 99+ is different and more complex than the pre-99 years. You can find ported heads for the NPI motors for a decent price and get some really really good numbers out of that combo NA or Forced Induction.

I would find a aluminum block bore it .020 over and stick some forged pistons and rods. Probably buy some ported PI heads and some cams. But your looking at 8k that should be everything taking engine out and assembled back in.
But not sure you will be needing all that possible hp. It would probably be cheaper to buy a 5.0 with some nitrous and be done with it.
What are your future goals with the car? That would help in picking what would be best.

depending on the condition of your current powerplant, I would upgrade to patriot performance ported PI heads, with a mild camshaft, and a 75 hp shot of nitrous, I think that would put you in about the 400 hp category. Early gt heads just suck, they dont even flow better on the exhaust side over .350 inches of valve lift, Your current heads would not be worth camming. PI's are so much better.

Woodward dream - what's the goal here ultimately? and any idea on the actual budget nos? Stay N/A or Supercharged? Will the car be raced? Is it a daily driver?

Hey Blue, i know you are somewhat intelligent, so i'd like to give you the chance to explain why to not put a 99-04 engine into a turd (aka 96-98 GT)?
Ignition, ECU, nor fuel system have any effect with installing it into his 1997. He keeps his stock coil pack ignition, infact it even bolts into the same exact location as his original engine. Everything is plug and play, no need to change anything. It will even run with the stock ECU. I've installed ~7 PI engines into NPI originally equiped cars.

1st. What's wrong the current engine? Don't fall into something
that you may not need.

Maybe i am just misunderstanding what you posted.
Would he not have to take the fuel rails from a PI motor and modify them to work with a return style fuel system?? Also don't the PI motors run on the OBDII diagnostic system and the NPI motors run on OBDI? I thought the ECU had to be changed also for the ignition system since his 97 has 2 large coil packs intead of coil on plug setup? If I'm wrong on this feel free to correct me. I know it can be done, I wasn't implying that it can't be. I just thought for simplicity, swap like for like instead of getting into something way more than a motor swap.

Nah, you can bolt on the NPI return style fuel rails right onto the engine, and the coil packs too. The only issue you'll have with an ECU is it will trigger the PATS (passive anti theft system) light, causing a no start condition. But take the ECU to Ford or an SCT/Diablo/Autologic/Etc tuner to have them disable it.
It's actually a direct swap, or damn near. It's actually, in my opinion easier and a better solution to the PI swap. You can find a complete, ready to roll PI engine for 900-1200 bucks, while the PI headswap still cost 1100 in parts. Swapping an engine is 10x easier than doing a headswap, especially for an amateur.
Putting a PI engine is exactly what I did to my car. I keep everything stock that came on the car and just had the new engine put in with a custom chip. I only paid $500 for the full engine.

Mark, I'm swapping a 1997 SOHC with a 2000 SOHC engine keeping all the old equipment as you stated here in this tread.
Do you know what causes the ECU to trigger the PATS light? Is there anything I can do to prevent this or must I have the PATS disabled?
