A 1979 302 in a 2000 mustang coupe v6?


My boyfriend wants to fix up my car, A 2000 mustang coupe v6. my motor runs fine, it has 180 thousand miles on it. Anywayz he wants to swap the motor for a 1970 something 302… I have no idea about motors. Should I let him?

No, that 302 in stock form has no more horsepower than your V6. The 70s strangled engines with emissions equipment, lean carburetor tuning, cam timing optimized for fuel economy and plenty of other stuff. This resulted in ratings ranging from 120 net HP to roughly 150 net HP, your engine has 190 HP. Plus, if you intend to pass state inspection, your ECU needs to read information from your various sensors that aren’t on models from before 1996, or your car needs to run on a &quot:sniffer&quot: or exhaust gas analyzer. Either way, it won’t pass inspection, and all the cutting and welding will have to be done again to put the stock engine back or you’ll have a car that can’t be driven on the street. So, essentially, he wants to put a heavier, slower engine in your car to make it a non-street legal, slow track car. Seems counterproductive. If he wants to put money into upgrading the old 302, it would be cheaper and easier to find a wrecked 2000 GT and pull the 4.6 and drop it in. Then you’ll have a much more reliable engine, you’ll pass inspection and you’ll get the extra power he thought he’d get from the old block.

For a Windsor to even fit in a 1999-2004 body the K-member needs to be swapped out for an aftermarket one made for Windsors. If the engine is a built high horsepower one then go for it. If it’s just a plane jane stock engine then it is nowhere near worth the trouble. There’s much more involved than just the motor alone, too. You have to swap the rest of the drivetrain and redo a lot of wiring.

if it aint broke don’t fix it. a 3.8 bellhousing will fit a 302 it wouldn’t be wise though. it should set in there. may have to swap out a cross member or oil pan to make it work. i wouldn’t though. if he’s think another engine is needed, go stock. no pains there. not to mention the inspections you’ll pass. it’s not like there isn’t a ton of aftermarket parts for that car anyway. in the performance department, you likely not gain anything really with a stock motor from the 70s. get another v6. you’ll be better off. better yet, if it’s running fine, not knocking, burning oil or anything let it be.

thats funny that only 1 of 3 actually noticed…. a GT is a v8 there is no such thing as a v6 gt mustang.

No, it will break things and be illegal. Engine has to be the same age of the car or newer for a swap to be legal.

Absolutely not. That’s the goofiest thing I’ve heard all day.

It’s a disaster looking for a place to happen……..

it won’t fit
