All of these mentions are all good choices. My first pick would have been the the 5.4L V8.

 

Oh,.. I miss understood the question. I thought it was just Ford motors.

You are right about the 427 tri power motors. The L88 was a pretty sweet motor. Solid lifter, TRW 12.5:1 domed pistons and loved to rev. How ever,.. the LS6 was pretty much the same set up just more stroke and made more HP. They had an LS7 crate motor option also,.. though no LS7 ever made it to a production car. What GM was doing was not lying,.. but not telling the whole truth either. The L88 was rated 425hp at 5200 RPM. What they neglected to mention was that the same motor made 500hp at 6500 RPM.

But now that we are talking about ALL motors of all time.
hmmm,.. decisions decisions. Wow,.. I could go in a 100 different tangents on this subject

The GT and Shelby GT500 5.4L still stands as my top pick for the reasons I stated in my previous post. I've read a few posts where guys with 03/04 Terminators were claiming 900hp on their stock short blocks. Incredible when you realize that we're talking about a 281ci motor.

But in the Muscle car era,.. the Buick Stage 3 455 in the 1970 GS was the absolute all time king of HP and torque. Pontiac had a tri power 421 in the Bonnevilles that made some outrageous HP numbers as well. I cant remember the numbers for the 421 but I remember the Tri power 421 and the SD 455 were very close. When I had my 70 GTO my 400 was beating many 455 powered cars. They would get me off the line but I would reel them in and take them on the big end. They just couldnt rev like the 400.


LS1 makes great power for what they are. But even the mightly LS1 is limited. They start breaking at the 600hp level. Havoc over on N2S was pushing close to 600hp and well over 600 trq before his motor chewed up the bearings. And that was just a bolt on LS1 with lots of nitrous.

 

Buick GS ftw. My dad had a blue one with the white convertible top, we called it the smurf.

 

426 hemi w/procharger gameover

 

A procharger on an old school Hemi?

Do it right,.. GMC 871 on there.

NAH then i cant see over the blower im short lol

keep it sneaky

 

It's hard to beat a boosted ls engine.

 

the 2.3l Turbo, the 2.0l nissan and the rb 25

 

Hemi and LS...what is the stock rods/pistons good for? I think the LS rods are on edge around 5-600hp?

 

I believe the intent of this thread is for Factory stock long block motors. No aftermarket guts. All the blower/nitrous/turbo you want on stock internals. Given that criteria, the GT/GT500 5.4 will stomp everything else. The 2JZ can't hold a candle to what that motor will do, stock for stock. The '03 Cobra motor is a good choice, but the 5.4 will beat it every time by at least 100-150rwhp.

A hemi with a blower always makes killer power, (top fuel?) but with the stock rods and pistons they came with back in the day, you better have a diaper ready.

The RB25 26DETT, are cool, they make good power in stock trim, and for their day, (along with the 2JZ) they were the king of the hill by far. However, today, that GT500 will wipe it's ass with all of 'em.
