    Exactly my point.

    I'm thrilled your even asking questions about modifying that engine. Are you absolutely married to that platform? I have no idea what kind of aftermarket is available for that engine, but if you can get the valvetrain to take it and get that thing to actually breath at 5k you could be looking at serious gains. Tell us the stock engine specs. You'll find all your extra power in the heads along with a compression bump, so pistons. If the ports suck you may need to have the heads cnc ported. Expect to spend thousands on any upgrade that isn't nitrous but I'll be glad to weigh in on anything you find to help you given my limited experience here.

    Imbecile.
    With a college degree in mechanical engineering.
    And a completely custom Studebaker Lark in my back yard, with an old flathead ford in it, and a Paxton SC, a 4.12 truck diff, four link rear suspension, semislick tires, and a cut hood.
    and that took time, and money.
    Also, yes, I do use cheap parts.
    Reason:
    I am broke as fuck.
    Also, did I mention that I actually am not an imbecile?
    Oh, you gathered that.

    With decent driving skill, so do i.

    Quick side bar. Check this out and tell me if I should pick this up as a project car. Only needs a fender really and the heat doesn't work. Few little things but classic car on insurance and NO emissions. Maybe turbo this instead of the coupe.

    Sort of. I really do like this little car, but at the same time I know that, other than having a decently torquey motor and OK pedal positioning, it's really hard to find the weak point because the whole car is pretty much broken as designed. It's not so much a matter of any one thing being wrong with it as almost every single thing on the car being wrong from a racer's point of view.

    Not sure about internals, but what I've seen of bolt-ons is not encouraging. V6Z24.com even has a tutorial for making your own cold-air intake from Home Depot-sourced materials, which would not, theoretically, be necessary if anyone made a CAI for it. Their design sucks air from under the bumper; I'd rather cut a hole in my front panel (where the grille would be on anything not a Cavalier/Sunbird) than ruin my ability to ford large puddles (and small streams).

    Valvetrain is OK into the high 5s, like I said. Also, I doubt the heads are the only bottleneck. It was a GM disposacar, and I've seen the exhaust manifold. Manifold, singular. It looks like pure back pressure in its elemental form. Like, if there was a back pressure mine somewhere on earth, those manifolds are what they'd be pulling out of the ground there. Yuck. (I'm also not sure if anyone makes a better one of those, but I'm not holding my breath).

    In other words, don't bother trying until I've escaped from fast food. Good to know.

    Cut a hole in da hood.
    Then PVC some exhaust together out of the hood.
    Simple.
    (Do not actually do that, unless you really want to.

    I'm on a shoe string budget too kind of. Don't give up. I drive Hondas cause I can afford to modify them. Maybe a 240sx if you hate fwd? Get something Japanese that handles well, than give it POWAAAA.

    Ehh, an old Camaro, from the eighies, are trusty-ish, and a paxton'll get the power up.

    >buys cheap parts
    >tries to build high RPM engine with said cheap parts
    >complains about high RPM engines
    >generalizes that all high RPM engines ever built/to be built will explode

    This is why you're an imbecile.

    Also, it's the fault of mechanical engineers as to why vehicle recalls exist, why bridges collapse, why ships sink. They'll give any idiot a degree, all you have to do is give them money and get a C average.

    I kinda want one of these. A local agency is selling a bunch off.

    Ugly as sin and the epitome of mid-2000s gm garbage, but it seems like it'd be fun for a bit. Torquey v6 and fwd. Burn the front tires off then sell it.

    I implore you to refrain. Supercharge the vic with that money you wild horse you.

    OR, go find a 90 year old lady with a Buick Park Avenue Ultra, Olds LSS or Buick Regal GS. Get your 3.8L AND your supercharged needs.

    Pfft, I'll jump the vic a few more times, beat it down real good, and sell it for a profit.
    Then buy another one. Rinse repeat.

    If you're using cheap parts, of course the aren't gonna hold up to high revs. Machining tolerances will be lower, casting beads more frequent, materials flimsier.

    Wanna push high revs. Get forgings. But they cost money.

    Using cheap parts is asking for parts to break

    And I get that, what I meant by cheap parts was the fact that the Flathead was trashed, and instead of trying to get it to 5000 RPMS, I kept the stock revs (3800) and put go-fast parts on it.
    What I meant by cheap was used.

    I hope you realize that hiring a "mechanical engineer" is different than actually hiring a mechanical engineer with two fucking cents.
    Yes, my first post was pretty generalized, but was based upon previous experiences when parts I used were super expensive and actually good. Case in point, titanium conrods, three-douces racing manifold, very high performance headers, high rise intakes, ported intakes, and a hell of a lot more expensive stuff like that, well, those parts were for holley performance team, and I work with them part-time, and they needed a high RPM motor, and fast.
    Even built to Holley's specs, it still broke at 6700 RPM.
    If you read my post it said "street car", what I think he means is something he can go bang around in, but still have a daily-ish car, and I do not think he wants to spend months on a street car that might or might not break anyways.
    And, if it's OHC, he'll have to re-time it.
    OHC is nearly impossible to time right unless if you've done it all your life.
    Hey, I'm not saying me either, I stick to OHV most of the time.

    I love how you keep trying to justify your idiocy. Dance, monkey, dance.

    And an OHC engine isn't any harder to time than an OHV engine. Timing is timing, it's easy when you're experienced, hard when you're not. You'd know that if you didn't get your degree from the bottom of a cereal box.

    If anything timing ohc (single or dual) is easier as the cam pulleys are more accessible, it's otherwise the same. Though your name change hasn't concealed your real identity btw, we all know who you are

    Quite often those things are not the fault of the engineers. Quite often it will be budget cuts, time constraints or inaccurate problem descriptions for the engineers to solve. Equally pretty much everything else on the planet is also the result of engineers, and most stuff works pretty well.

    Unless its something I've programmed that has broken, in which case it is indeed a hardware problem xD

    If you get the timing chain one tick off of the mark, well, death to your sanity, it will not run right.
    Also, i am not justifying my "Idiocy", how can i justify something that is not me or does not define who i am?
    --- Post updated ---
    Yes i know, you all know who i am, the infamous 55Buick.
    i never tried to change my name to conceal who i was, i changed it because i wanted to.

    Dohc is a joke to time. I love timing belts.
