    Mild 383 build

    Last one, I don't agree with you and you don't seem like your gonna agree with us, lets just focus on the OP build, he's not stroking it anyways. Combustion creates pressure, psi, my eg.. Was a 1000 psi (the psi of a average engine, full throttle) not a 1000 lbs of force, so the force from the...

    So basically a 500 cfm 2bbl is half of a 750 cfm 4bbl.

    I got my faith in RRR, I’m sure he’s measured the fuel droplets and there within spec :)

    Mild 383 build

    This Video just came up on my feed for some reason, swear google/YouTube monitors what you saying. The second half of the video @ 5:15 is the 383 Chev vs 383 Mopar might be an interest to the OP. The video starts with the RV 440.

    Mild 383 build

    Say the combustion is 1000 psi, you got a 1000 psi pressing against all the surfaces inside the chamber which includes the total top of the piston aka piston area, so each square inch of the piston is getting a 1000 psi.

    You can make as many dumb analogies as you want, your just wrong.

    Mild 383 build

    It's 100 lbs per square inch not a 100 lbs divided by the area in square inches.

    Especially now days with the parts and tech and knowledge available to us you can almost make any engine work and it don't take much to make an A Body fun/fast.

    He assumes that a bigger bore will see less pressure.

    Mild 383 build

    Why would that be ? My position was that torque is gonna be about the same for a given displacement no matter what the bore to stroke ratio one doesn't really have an upper hand over the other. I don't think this the best analogy but it will do. Since even it shows your wrong. The 5/16 rod...

    Thing I don't get he doesn't like or even think 318 can even be made to perform (torque) why is he's really given advice on them. I'd rather him just say they suck get a 360 and move on. Most don't think /6 is the wises performance platform but most don't go down there and pester them and...

    Best cam for the street both power & sound

    And for some reason he's dead against hopping up a 318 beside duals and tune, he says you can't put a cam in cause of under 3,000 rpm performance with stock stall and gears fine but then he recommends a aftermarket stall and deeper gears but even after installing those stall and gears your still...

    David Vizard - Which to prioritize - PORT FLOW or PORT VELOCITY?

    If you go by these formulas for a second (say there in the ballpark) and calculate what's too big for a 318 to make peak power at 5,000 rpms the trick flows come out to be slightly lower than the lowest acceptable velocity. But if you put a set of trick flow on a 318 even with an rv cam it's...

    David Vizard - Which to prioritize - PORT FLOW or PORT VELOCITY?

    You really just like being a troll don't you? this is exactly what you wanted a bunch of people riled up at you. You have zero intentions at an honest conversation, I use to think you where interested in figuring all this out, but obviously not.

    Apparently it's not his job to know, just to harass people when making reasonable choices for their builds and to show them how some car made x hp & e.t. with "smaller".

    True but nobody is arguing it is. Hysteric is strawmaning like we are.

    David Vizard - Which to prioritize - PORT FLOW or PORT VELOCITY?

    Shorter rods move away from TDC sooner than longer rods that dwell longer a TDC, so with longer rods there's little piston movement so overlap and velocity are generally starting off the intake charge, shorter rods the also has some piston movement to help early on the intake charge supposedly...

    It's to help to get you into the ballpark, it don't need to be 100% accurate, and it's probably far more accurate than any actual advice you would probably give, when people are coming up with a combination.

    1. This thread was in opposition of what DV was saying. 2. Your the one on here being super judgmental, not DV, telling everyone that they need to up their game and build engines like the 1%'er that do highly develop R&D for the perfect combo. Which I'm pretty sure your not living up to the...

    Plus it's seem like gears and definitely stall is the last mod that people are generally willing to do and usually not by much especially for a mild applications.

    Tell us about the amazing droplet size you were able to conjure up in you highly trick out engine? tell us how you engineered it to the nth degree? must be an amazing journey we all can learn from.

    Like 2-5 lol No your haven't, you think you have cause you strawman everyone's argument. You don't even know what I grasp, cause your not looking for honest discussions, you just look for threads to interject your strawman arguments. I was a child in the 70's

    That chart looks like if from the Pipe Max software, and pretty sure most of the equation are too. Go ahead, check it out see if its up to your standards. Again I'm not making a case for these charts and equation, I'm not trying to prove them correct or not, wasn't the point of the thread.

    That's one car, doesn't mean the results for that car is universal to every one else's car. It's interesting but you would need a few thousand more examples, to offset the last 65 years or so of racing and hot rodding.
