I just got wind of a 99 z28 camaro hugger orange with a 5.7liter engine, if im not mistaken that is either the LT1 or LS1. Could be purchasing it, i decided that the 84 camaro was too much and too old for what it was, sorry bout the last thread i made, and wasted peoples times, only reason im asking this question is i currently turned my home phone off, my dad is out of country(he has a cell) and im still looking into cell phones, and the dealership isn't to close to me. So im just curious bout what kind of engine it is before i go chasing it. BTW erverything on it is stock except the flowmaster mufflers, goin to add SLP exhaust system, and possibly full hotchkis suspension. Was looking into getting either a super charger, or a pro charger something that adds some serious pounds of boost, so if you know of anything with good hp adding and i didnt mention it, hook me up. What would the best exhaust headers be for my application depending on my engine type? And the best Cylinder heads for it as well. Thanks.

in '97 the corvette got the LS1 (genIII) instead of the LT1 (gen II), a year later passenger cars with the 5.7 option started getting the gen III engines
And just one thing about boost, the higher the gauge is doesnt necessarily mean more power. For example, In the case of putting a roots blower on a oval port BBC, the boost numbers will be extremely high due to the small ports, which possibly could be working the blower past it's best efficiency and actually hurting horsepower, if you are getting a supercharger as a bolt-on to a stock buttom end LS1 the boost is going to be low (~5-8 lbs max), where it should be, the LS1 still budgetly employs cast aluminum pistons, powdermetal i-beam rods, and a nodular iron crank. A much stronger buttom end is needed to for extremely high boost pressure and the resulting temps and forces associated with these things

Ok so it is an LS1 engine then? well im not sure of the supercharger at the moment, i know i wont be getting anymore then 10 lbs of boost max. That is even if i go with a super charger, still in the thought process, i would just like to get the most horsepower out of hte block as much as possible, would a bored and stroke be necessary and replacement parts for street/strip be good and get me some decent ponies, i would really like to get like 435+ horses. Im still young but i got a good paying job so i can afford that stuff, plus my dad is a mechanic and has all the tools, but never the time go figure. Well thanks for all and any info PEAce.

it helps that your dad is a mechanic, then he can probably help you with the removal and re-installation of the engine, but once your inside the engine it's a different story. Boring the LS1 enough to make dividends isnt possible, unless some trick machining is done with new cylinder sleeves, stroking of the engine is possible, but then demands a new crank and new pistons (if not new rods). And getting into the engine internals brings up things like how much experience do you have with a engine?, do you have a good machine shop (they are extremely hard to find) that can do the critical machine work for you? your statement about getting the most horsepower out this engine thats possible, sorry to say, sounds like its coming from a 14 year old with his first car that wants to show off to his buddies. I shouldnt be saying that since im only 17, but i suggest you get some knowledge of these subjects yourself before diving into a engine. Also while im preaching why do you want the most horsepower possible? do you want to go the fastest? well horsepower isnt necessarily always the key, especially if it also a car that needs to get you to school (read numerically low rear end gear ratios and durability/mileage concerns and low rpm stall converters ect) if you really wanted to get the MOST HP out of this engine as possible it would demand extremely frequent tear-downs with state of the art extremely high priced parts that someone only with a beer wagon sponsorship could afford. Your want to get to 435 HP doesnt say much, if you knew your engine had 435 peak HP @ the flywheel then you could take it a chassis dyno and see what kinda power you get to the wheels and then you could do estimations of quarter mile times, otherwise "wanting" a certain peak HP and ignoring the torque curve is basically for showing off to your friends. All in all this costs more money and takes more knowledge and experience than you think, and believe you me, age really helps "cloud" this
here is a start to the information that you should study http://www.hotrod.com/techarticles/50638/index.html http://www.hotrod.com/techarticles/67018/index.html http://www.chevyhiperformance.com/techarticles/86218/index.html http://www.chevyhiperformance.com/techarticles/148_0207_tech/index.html http://www.chevyhiperformance.com/techarticles/148_0405_ls1/index.html http://www.carcraft.com/techarticles/116_0412_slp/index.html http://www.carcraft.com/techarticles/77998/index.html http://www.popularhotrodding.com/tech/0411phr_sts/index.html http://www.popularhotrodding.com/tech/0409phr_gmpp/index.html
my final verdict, if you have a engine that is a good platform (low miles, doesnt use oil, not heavily worn) and you have the $$$ then a bolt-on supercharger is a good way to go if you are just looking for performance, but this supercharger will increase wear of the engine quite a lot and more than likely lower your fuel mileage, and this fairly drastic increase in power will probably require a way to put it to the ground, this only adds to the problems and cost and may even interfere with driveability issues if you arent going to be a regular at a drag-strip, then just drive the car and enjoy it, they are factory hot rods! even though it is unnecessary wear, you can probably already do burn-outs to your hearts content (at least until that 6500 RPM fuel shut off comes into operation) haha

lol, well thanks a lot, how old did you expect me to be? im really not too far ahead of the game for my age, infact a friend of mine that i talk to that used to frequent the Hot Rod Board, who owns Rascal Cams, started collecting dyno information several years before he was my age and started looking for trends in them, which lead to the math that he uses today, which i already asked, he wouldnt sell for millions of dollars, haha, and im sure that bogie probably graduated with at least one mechanical engineering degree before my age as well, lol. Im book smart (at times), but i dont really have experience needed yet to go a long ways in the professional racing world, which i dream one day of working in. While im shooting my mouth off abouy myself, i would just like to say that it is nice having a little trio here on the CHP board between you, me and bogie that can help each other (well bogie helping us two at least), and help others as well, even though bogie does the hard work, at least we can put in our 2 cents every once in a while. I hope to be learning from this board for years to come, so keep up the good work!
P.S. im not even officially 17 yet, give me till the first official day of summer
