Entertain Us - 400 sbc question

[fastazz81]

They were all on in the correct order, it was a two barrel though.

 

[Bent77]

I have two we could put together and test if we find a money man to sponsor it.

I bet they make 400 if you connect them lol

 

[fastazz81]

Nah. 400 will run out of air at 3300rpm…

Due to the crappy heads and two barrel intake.

Yup, by '79, they weren't great.
The '70 400 that I pulled out of a station wagon was better, and rated differently.

 

[fastazz81]

Nothing was great in the late 70s or early 80s for hp.

 

[Bent77]

Ands what the bent one is ignoring is I didn't give a crap about the horsepower number, just the torque and the rpm that it peaked at. Midrange torque. Period.
No, they didn't have great heads, but look at the torque numbers and the torque peak rpm of the Olds, Buick and Cadillac engines of the late sixties and 1970.

None of those engines were turds, and the cam/port numbers on all of them were more proportional to size than the 400

350 engines didn’t have enough air, and the 400s used the same port size/shape and same PN for the cam. Therefore it was short airflow by an additional 11.42%

400 was never a performance engine in stock form.

Upgrade some parts and they can go.

Did you use a 350 to pull it out?

 

[6872xtc]

Nah. 400 will run out of air at 3300rpm…

Uh-huh. Sure. Not what I found with mine.

 

[Bent77]

Uh-huh. Sure. Not what I found with mine.

But it’s not stock. That’s the condition

 

[fastazz81]

@6872xtc shouldn’t you be doing something else after date night other than debating a antiquated poweplant?

 

[6872xtc]

Mine was stock for several years.

 

[fastazz81]

I thought we was talking stock, if we are talking built , more cubes is better.

 

[Bent77]

Mine was stock for several years.

Did you win some truck pills with it?

 

[Babaganoosh]

@500$k5 probably remembers more of what we found years ago.

He’s pretty old, think he might have years on you.

 

[fastazz81]

They all started as stock , then they overheated and the cranks got robbed to build a better engine.

That would be great!!!
29 years of marriage, AND the 21 yr old daughter being home slows things down some...


Or a lot....

Unless it’s a 305, then all bets are off
