32HP for the standard models and 39HP I think for the NASCAR versions and a couple of factory lightweight Moostangs for Superstock. They achieved the ect (ect!) extra HP by using a higher compression piston in the left bank in pot No3 to effect a 'powerstroke' This is where they got the idea for the later 7.2TD decades later.

cheers heads1st,. And thanks for the useful info trader 84. must remember to put a shorter sparkplug in that cylinder, dont want to have the pop up dome top piston smash the plug and close the gap

how did they make so little power from such a big engine!39hp isnt even enough for a decent dirt bike!

QUICKSTICHwhat a shame you done too many trades you shoulda stopped at 429and not 492 .

could alway go to 512 cubic inches, a stroked big block.

john kaase makes his big block ford boss nine motors up to 800 cubes, so i can aim for that.

The 69 4V 429 produced 367 hp. The books are out in the shed, so that's off this screen in front of me.

They don't need hp.

wow these are sad numbers, my trusty 340 although advertised ratings were 275 hp, all the engines came off the factory dyno at 320hp. thats nearly 90 cubes less.

51 bhp / litre is not startling

Funny how someone asks a simple question, and the old "My dads got a bigger one than your dad!" comes out.
I had a 327 Camaro that was quoted as poking out 350 hp, but I've since found out that was wrong. Then I brought a 351 Mustang that had to have the hp listed at 266 to satisfy new regulations. The Camaro was about a sec quicker over the 1/4, but after that the Mustang was far better.
These are cases where apples can't even be compared with apples.

Ive had lower HP cars that put out great torque figures & really have punch & have also had & been in so called fast cars with big dollar big HP motors that just dont 'feel' powerful at all. Id rather have torque to burn at low rpm on the road than HP figures on a dyno & I think thats where many misunderstand big blocks

Here ya go -
The 327 produced 250 - 350 hp depending on the carbs/intake. The 305 was rated at 290 hp @ 3500 rpm off the factory floor (for insurance and racing reasons) But could actually crank out to 360 hp at higher revs. Perhaps my 327 was running under the same bullshit, so it actually did crank out 350.

I had a big journal HP327 once, it was meant to be factory rated at 300 HP. So the story went anyway.

Exactly
I've got a Subaru and a Mustang for playing with. The Subaru would piss all over the Mustang on the open road, but when the Subaru hits a steep hill it changes down, up, down, screams, so I back off, and next thing you're doing about 80 k's to be kind. The Mustang doesn't falter a bit, and with slight extra peddle it cruises over the top in hi cog, still at 100.
Sure - the Mustang probably wouldn't out scorch the Subaru if both were nailed. And I don't leave the Subaru in D on these occasions - it gets knocked down manually in order to maintain speed.
