In the 80s, we thought the manufacturers were going to kill the V8. Now, a smallish displacement V8 can hit 1,000hp with off the shelf parts relatively easily! It's a good time for engine performance!

Fun fact, in SOHC format most guys (who I have met) who have owned both say the 4.6l f150 was better for towing than the 5.4l likely due to the fact that the heads were sized for the 4.6l and then just slapped on the 5.4l with everything else about the same and choked it out.

The 2v does fine for a 281 cube motor from the 90s. It makes as much or more power than the old 302 h.o. and torque stock or modified and when it comes to modified forged internals vs forged internals the mod motors can make way more with stock block than the old 302. Idk why people think the 2v sucks it's just as good as the 302 in every way and for big power builds it can get there easier and cheaper than the 302.

Really good video. Thanks for this comparison.

Well it should be super easy to find a mark Vii lsc in a junkyard and lots of people will argue its a better engine/block combo then the cobra minus the 03/04 cobras forged internals of course. I know with forged internals the teksid block will hold stupid power numbers but the early modular engines are known for weak rods but i would love to see a big bang on an lsc

Horsepower is great and all but when it comes to racing I'd rather have an 8 second 800 hp car than a 8 second 1000 hp car. Power production is one thing vs speed. I'd like to see comparisons of equal hp engines put into the same chasis to see which one is faster. Good video man.

i think a revisit to the mods would be nice and bring a 4.8 ls along. those older test were done when they cam selection wasn’t great for the mods and the mods motors in your test are still using oem intake manifolds where the ls is using a good aftermarket one. the aftermarket has grown for the mod making it easier to make more hp. keep up the great testing.

​@@alberthunt8501 not a bad idea. Manly rods could prob get you to 600 wheel easily on stock cast crank.. the rods were the weakest link in the engine once those are upgraded the rest of the parts can take quite a bit more power.

Shoulda done a 4.7 magnum and 4.8 ls or 4.7 and 4.6

I love these ignorant clowns thinking the LS is capable of that. There's also the world record standing mile ford GT with a factory block and heads making over 3,000 hp and 300.4 in the mile in 21 seconds. No LS even billet is close. 263 for the comparison lol. LameShit LS

How about a 4.7 chrysler v8?

While on a standard 4 valve 4.6 that's not an 03/04 Cobra doesn't have the Forged rods yeah it's not going to hold as much power of course

Wow, you pulled the boat anchor out of the sea... (4.6)

What about 5.4 w/ VVT and the 5.4 without. Anyone out there put vvt heads on a non vvt block?

I've seen 500rwhp from stock SC'd PI 2v mustangs. Risky because the weak pistons and rods but impressive nonetheless. Been in a new (at the time) terminator Cobra with a blowzilla w/ 667 rwhp (again engine totally stock), owner blew the tranny at 11k then the engine at 16k. He never fixed it, sold the car as is with 16k miles (he was the owner of a mustang shop also). The power was literally tearing the car apart, the interior trim pieces were falling out of place, everything in and on it rattled and shook under acceleration. This is why I always modified the "big" cars instead (Mark 7, Mark 8, Thunderbird, Cougar).

I've never heard of people's terminators falling apart from 667 rwhp nor have I seen too many terminator engines going at that power level at that low of miles it sounds like your friend and/or his tuner didn't do the car any favors. They're pretty good cars and they can live easily past 800 wheel many have done it.

Are you trying to see a simple yet crazy 2v combo with boost? Stock unported PI heads I have one that’s almost finished and we’re hoping to see 900whp+ on a mustang dyno

I’ve always been curious as to what the true power limit is on a stock 4.6 2v bottom end is. Everyone always claims 400-500 RWHP, but that’s always boosted, and no one ever modified ring gap as far as I know of. I’m wondering if the issue is truly rod/piston failure, or if it wasn’t ring end gap butting together causing piston/rod failure. It would be interesting to see for sure what it truly is.
