    Best cam for the street both power & sound

    Agree on both parts, but the rear gears are very rewarding…when you get them right. The Torque converter is probably the best performance upgrade you can make with an automatic car. Night and day difference.

    I’ll bet a lot of wheels are turning since the John Force wreck

    Even so, all these race sports, pretty much across the board, are safer than they were some years back.

    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...

    A-833 2.47 1st gear change to 3.09

    No I bought my last one from Brewers. I had to build a 2.47 trans and needed one myself. He sold one one that was not prefect but plenty good for a very fair price.

    Got zapped by my Engine !

    Just to be technical, you were not electrocuted, or you would not be typing this. You would be dead But be CAREFUL. Some modern ignition systems actually generate enough power to be lethal.

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

    Right. But a certain guy on here wants you to THINK he has a better way, yet he NEVER says HOW he does it. I said a long time ago the dude is poser.

    Mild 383 build

    That should take a good size over bore, is it a 60s or a later block.

    You pointed out that Darin Morgan said he is a velocity manager did you not. Why is velocity important.

    I’ll bet a lot of wheels are turning since the John Force wreck

    I was always under the impression that the automatic chute deployment system was not active at the top end.

    Any chance you have an A body big output spline main shaft laying around you’d like to part with?? PM me if you have a critter like that.

    Cheap *** headers at it again!!

    One time does not a crimp-free header make. I knew I was done with that crap when I went round a banked corner that had a VERY slight crown and it crimped em shut. A little extra compression in the suspension and a little less clearance between the tires was all it took, and I had six inches...

    No, you said his **** doesn’t work because it can’t. So I suggest you call him and tell him how stupid he is and let him see what a fart smeller you are. That guy has forgotten more than you’ll ever think you know. To trash him and his work is chicken **** and despicable. Go tell him rather...

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

    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.

    Best cam for the street both power & sound

    a cam or intake & carb swap is wholly within the wheelhouse of the general hotrodding public or shade tree hobby types. whereas gears, unless you're talking about swapping a pig on an 8.75 is a little more involved on a number of different levels: skill, specialty tools, cost or even...

    Don’t believe that bullshit. His software works. Hysteric has no answers. Never has. He lives vicariously through individuals we can’t ask and probably if we could ask they wouldn’t answer anyway. I doubt he’s ever built or tuned anything.
