Like seeing a bad *** 318. Iron 318 heads ?

It's all good, most of us aren't experts we're all bound to F up time to time, as long we learn something and move forward, this debate gave me better understanding of all this than I had before :)

I knew that but didn't exactly know how, Ideal gas law confirmed that 100% for me and this gave a good explanation how, didn't realize the space of the particles changed in relation to the different areas of the chamber at various distance that have different amounts surface area averaging it...

...shape, not the volume) will have no effect. To demonstrate this, assume the original container is a cube of 1 m³ (with each side a square of 1 m * 1 m) , and you change it to a rectangular box with width and length = 2 m and height = 0.25 m (top and bottom side become squares of 2 m * 2 m...

He'll just ignore all this, he's built his whole argument on p = f/a which be fine if were talking hydraulics not combustions of gasses in a sealed chamber that the volume expands over time. Obviously this paragraph from his grade six text book is all that's needed to explain thermodynamics of...

It's literally in it's name PSI, Pounds Per Square Inches, Force = Pounds Per Square Inches x Amount of Square Inches, Eg.. 1 psi x 100 square inches of surface area = 100 lbs of force. Were not looking for pressure, were looking for what the pressure does to the piston, were looking for the...

Probably not since it's only called a stroker compared to stock stroke. Chrysler seemed to love Big bore's shorter strokes and long rods. They probably felt the 360/383/400 covered that need.

Bet the trick flow heads helped a lot getting those torque numbers, this shop is actually a reasonable distance form me.

Don't know about cheaper, since the 380hp crate is the same as a 5.9l from a junk yard just with an aftermarket cam and intake. Saying that I'm not knocking the 318/390 it's a cool little build most be happy with especially with a set of headers, just thought if you were thinking about a...

it's not bad but if you look at the 380hp crate basically has the same power curve at the same rpms and that's just a 5.9l with cam headers and 4 bbl. https://www.motortrend.com/articles/mopp-0303-360-crate-engine-buildup/ Mopar Performance 360 cid 380 hp rated RPM TQ HP 2500 380.6 181...

Butterscotch definitely is a better descriptor.

I don't know why anyone takes old factory power ratings seriously anyways.

You think the 383 struggles a little torque wise besides intake and exhaust manifolds, is stock big block heads aren't known to flow lots of air and sure the port csa and cc are a little on the large size especially for a 383 that makes peak power at 5,000 rpm ?

Still fell short lol 350 hp and 400 lbs/ft not bad with stock intake and exhaust.

Nice car, color definitely is different don't think I've every seen that color before, right tires and stance can make anything cool. My sunfire yellow is starting to growing on me.

Definitely performs well under 6000 rpm, just surprised if he (dyno operator) was encountering valve float at 116 mph / 6000 rpms he wouldn't mention it.

You do and you'll be able to answer this question for us :) I have a feeling it's gonna work a lot better than most would predict.

230 cam (which ain't crazy big) and magnum heads equal 400 hp, I imagine with trick flows you still could hit 400 hp with less cam, which way is generally more streetable ? More cam less head flow or vice versa ?

Some how I don't believe him :)

Instead of this, you got to use scientific principles related to the subject matter.

Not one thing about surface area just Pressure, Volume, Temperature. Look how this imep and bmep graph would over lay on the ideal gas law's one.

I admit before this thread I had an vague idea psi was based on volume, knew how that psi interreact with the surface area of the piston and Plan, Bmep etc.. only cared about overall volume and that fit with everything I seen, But wasn't until I just found ideal gas law I understand how.

No he doesn't, that's the problem, he keeps saying a (1000) lbs i keep tell him it's a (1000) psl. This what he thinks is going on, the combustion has eg.. 1000 lbs so say a piston with a surface area of 20" sq psi = f/a so 50 psi of pressure applied to the piston that's what Bewy is saying he...

For me it was worth it I have a better/clearer understanding than I did before.

Well from what I can find and kind of expected, that engines psi is based on volume not surface area, since engines of same displacement and cr have same volumes no matter there bore stroke ratios. Ideal gas law is P = nRT / V The Main ones that concern this discussion are Pressure =...

...smaller piston, longer stroke engine of same displacement on average for similar level of efficiency. Then there's really nothing more to discuss. *Edit, And this (below) explains that so unless you can prove below has no bearing on what were discussing think were done. Ideal gas law is P =...

I'd just keep the stock stroke especially if your using ported stock heads but you really want to go stroker might as well go with a 4", Makes the most $$$ sense.

I am not shifting the goal post you seem to take issues that there would be similar psi capabilities so I'm trying to answer you. I don't how many times I have to tell you I've never said more hp, I've stated from the beginning a larger piston will have more force for a given psi, that's what I...
