    Well, the way I see it, some of us just don't have the patience to suffer kids like this young boy who, for whatever reason, came onto a board of experienced rodders and tried to blow smoke up their derriers with some thinly-disguised ruse about the exhaust system on his ride.

    I tried to approach his query from a scientific point of view because it just didn't sound right, what he was telling us, but I never got an answer, not even a hint of an answer to my questions, so I bailed. This kid has a warmed over 305 with a flat tappet Thumpr cam and a $150 set of ProForm roller rockers and you can't convince me differently. Of course, we'll never know the whole truth now, because he lacked the integrity to hang on and prove himself. He even came back and deleted his original post, a juvenile move that cements his place in loserville.

    Son, like Ken said, you're a poser. We've seen kids like you all our lives. You're superficial and a product of the declining school and social system whose only goal is "no child left behind", no matter that they didn't learn anything, they got pushed to the next grade level and finally out the door to join the unprepared ranks of all the others out there looking for work who were not taught anything. As far as your not being able to slice and dice with us senior citizen rodders who have been there, done that, well, that will take experience and experience takes time. In the meantime, try to work on the honor and integrity aspects of your personality. Try to stand up, face the truth and conduct yourself as a man instead of deleting your intro and running away like a little girl.

    For those of you who don't understand my rant about the system, please see this.....

    tech and jerry, I have the utmost respect for you and your knowledge (and many others here), but I'm going to say it again, he was just young and proud trying to show off a little. And it's not like non of us have never done that. Unfortunately for him, he picked the wrong place. It's too bad he got his feelings hurt, however I've seen some of the members here act worse than him.
    So, Im gonna part this thread with one last tid bit; Don't confuse teacher with preacher.......

    Well.. too bad. I had hoped for better. Young fella needed to be taken under someones wing and taught some basics. A missed opportunity on our part.

    Tech, I didn't bother reviewing your link, polictical dogma and one persons "truth". And since it's in Texas, completely irrelevant since this young gun was from Canada!

    Who knows... maybe he'll come back? Sometimes I'm such an optimist!

    A little off subject but it reminds of a time a few years ago during a college football game one of the announcers was saying what each player was majoring in. A little of this and that until he came to a fellow who was majoring in "playground activities". Say what. What was he learning to do, to tech kids how to play tag, dodge ball, skip rope, hide and seek etc....... Give me a break!

    Hey so im sorry i buggered off but i just got mad with the people calling my a liar. I have issues with that kind of thing so I want to give it another shot because this car is my life. But first I want to make a couple things clear.
    I AM NOT LIEING!
    i gave you the information i thought you wanted but let me put absolutely everything i know down here.
    The car has a 350 sbc that was bored out to 355. It is a full roller motor. It has edelbrock aluminum valve covers, edelbrock 4 barrel carb with an edelbrock air filter, it has wrapped headers back to the 3 inch chrome tips (not straight pipe as you saw in the vid), it uses an edelbrock efi fuel pump and regulator to supply gas to the carb. It has an aftermarket over sized rad and an all new wiring harness in it. the internals of the motor i do not know. its been camed you can tell. The bill i was given by the man i bought it from was $10,000 for the crate engine and all the parts (and when i say all i mean absolutely everything, timing, water pump and hoses, all the electrics which were heavily reworked, all the wiring, EVERYTHING) along with the misc labor that was done for stuff he couldn't do.
    THAT IS WHAT I KNOW. I cant get numbers because the motor barely fits in the engine bay of that car so there is no way to get the numbers to prove it was originally a 350. and i dont plan on ripping apart a motor to show proof to guys on the internet that don't believe me.
    now the reason it was a video of the exhaust sound is because you can hear that audible change when you get to the higher rpms and i wanted to know if that is alright in a car with that kind of motor. the reason i ask on here is because there is no one that i know that knows anything about cars that old, NO ONE. so i only know what i can look up and so far i have been fine but i couldn't find anything on this kind of problem.
    And to the people that says that because im 17 i can't afford this so it clearly makes no sense to how i could afford it. I flipped alot of sleds, chain saws, quads and dirt bikes over the years and saved up my money over the years because i knew what i wanted.
    If you don't believe after all that please just go away and bug someone else, im not trying to be better then anyone, im not trying to say im faster then anyone, im just trying to get an answer so i don't destroy my car because i love it and i will not be able to get another one for a loooooooooooooooooooong time if has a catastrophic breakdown.
    Now sorry for the rant. Its 1:30 in the morning and i have a bus to catch in 5 and a half hours.

    The question i had and is what i was wonder about is as i stated above is hat audible change you hear when you get to the higher rpms alright in a car with that kind of motor?

    Maybe where ever you live you have issues with your system but up here its pretty good. declining school system? Maybe you are having that problem in the states but our schooling up here is doing pretty good! no kid left behind, what a joke. do you know what i personally have had to go through to get anything in life because i dont think you do seeing as you know absolutely NOTHING about me. I have had to do alot, because you are the kid left behind when you can barely afford to pay for you school lunch because every hard earned sent you make goes into the thing you love. And as for the whole "stand up your a girl stuff", I tried to stand up on a forum with people who as you've said "have been there, done that" for waaaay more years then a 17 year old kid that has only been able to teach him self because there is no one around here that knows anything about cars, our high school doesn't even have an auto class for Christs sake! I did my best, the info i gave was what i knew, i didn't lie or exaggerate one bit. so please next time you try to attack someone personally and throw in some political crap you identify with take a step back and ask you self, did i a senior rodder need to even bother my time attacking a 17 year old kid on the internet thats just trying to get help with a question he had?
    thanks for you time

    Good rant. Watch your language, lest you be seen as a young punk, rather than a young man.

    Maybe you two got off on the wrong foot, else perhaps poor communication (same difference) but tech is extremely knowledgeable, experienced, and actually forgiving. (Particularly towards respectful young men; more than young punks).

    How about re- reading the thread from post #1and see if the fault is yours.

    wow - things are getting interesting. I swear like a trooper when speaking but struggle to see why you need to use it when writing!!!!
    for what its worth - I've listened to your video postie thing from two posts ago - 3 times, an I can hear nothing that would worry me an I've got 3 smlblk chev powered cars on the road. when you button off, the exhaust note changes but i'd put that down to the exhaust not the engine.
    just my unpolitical 2cents worth.

    P.S.

    A car is just a thing. I don't think it should be ones 'life'.

    I've had material goods come and go.
    Lost a house and it's contents to fire.
    Lost cars in wrecks.

    A car is just a thing. Your life should aspire to a greater calling.

    IMO.

    Tie, I want you to check your fuel pump out, it is possible but unlikely to run a efi pump for a carb, volume and pressure are different beasts but often confused, that carb needs low presure high volume and that efi pump is kicking out way more than needed (psi) it would have to be regulated severely to even function correctly.
    I am glad you stayed and hope you learn something from the older guys, wisdom is something you aquire and not learn and it comes with hard knocks and these guys have it so just keep an open mind and learn, in the world of hot rods your bouncing around with some true super heroes (literally) here, anyone on here knows how many hours and dollars as well as sacrifices there are to build a car so your sort of preaching to a choir on that note. I am a scout leader so I devote a lot of time to teaching youth (for free) and talk a bunch about rods with young guys, how long something takes is irrelavant in our world of rodding as the toil invested by a youth is not in the same persepective as an adult, ex. many finished cars on here where probably started while you where in your early years of elementary school and countless hour have been dumped weekly into them, full rebuilds take anywhere from 1000 to 4000 hours to complete, something hard to even imagine when I was your age. Have fun, we need more youth into our hobby is my belief but use some respect as alot on here have earned it.
    Nobody is questioning wether your motor is a legit 350, though one of the best motors in history they are very very common in hot rodding they are wanting casting # for performance reasons as these motors came in smogger motors as well as high performance, ex you can have the best parts in the world but if your 350 has smogger heads on it its being strangled to death! (Most rodders keep a sacrificial sbc around just because) 10k is not much for "specialty" motors but for a sbc it is quite a bit to get into it as these motors are the cheapest at turning $ in horsepower and every motor has a limit on hp, in sbc's you should be getting into some pretty exotic parts for that kind of dough so thats why the questions, we didn't see shiny billet heads or supechargers, efi etc or anything, not saying it not possible just some tell tale signs they look for (valve covers and air cleaners are irrelavant). Take care & Have fun

    I'm not much on U Tube videos for analizing sound of engines running as the recording capability and then my playing the sound over cheap PC moniter speakers don't do it justice----------but I will tell you what the change of the exhaust sound is the result of (in my opinion) and its hard for me to be forward and state this as the info about what is on your set up is difficult to believe ( I am not saying your fibbing) because I can't see it and you haven't proven it--------the sound change that your hearing is coming as a result of changing timing and mixture complicated by tuning length of exhaust headers as they reach tuned rpm length and same as you back out of it.

    On a small block chevy, if the builder used roller rockers, he probably also upgraded the entire valve train to where it should easily be capable of 7000+ rpms------again , as your talking 5000 rpm I think some timing curve, carb tuning and utilizing tune length of the exhaust should make things sound better and rip on up to a much higher number.

    The fuel pump is an efi fuel pump. its running a regulator further up the line to bring the pressure down to a usable amount (i believe its set to 5 psi but its been awhile since i looked at it)
    and as for the questioning if the motor is a legit 350 "This kid has a warmed over 305 with a flat tappet Thumpr cam" i just wanted to restate that it was indeed a 350 punched to 355.
    and keep in mind that its in Canadian funds which is around 7k U.S. also remember that the shipping on the parts would have been more, our taxes here, etc... there is a stuff you guys down in the us may not know money wise when building up here in canada with our economy. I was just saying what the bill i was shown was.
