more info please...What vehicles are these engines in? Are they stock otherwise? Gear ratios?
And I think you are in the wrong forum. There is a theoretical racing forum on this board.

Idk get what makes the LS1's and LT1's so fast. I mean I know they were designed for racing/power after GM got over the whole peanut cat smog phase BUT isnt a 400hp 350 or 327 gonna blow a stock LS1/LT1 out of the water?

I'm kinda new here, but I believe that it matters how the cars are set up. I've seen a 200 hp v6 beat a 450 hp v8 because the v8 did nothing but spin the tires and the v6 hooked and ran.
All things being equal though, it should be close but I don't think that the 400 hp 350 will blow an ls1 car out of the water.....but maybe I'm wrong.

my 327 doesent sit their and spin tires. and a 350 is a better motor than an ls1 because its got bigger pistons and a shorter stroke so it can rev faser, and the 327 can smoke both of them

Exactly what I was saying. There is more to a race than "I have xxxhp and he has xxxhp" Your questions are vague. Just because your 327 beats one ls1 doesn't mean it'll beat them all. If its a standard, for example, driver ability factors greatly into the equation.
I'm not trying to bust your *****, but the more specific you are on this board, the better the chance someone here can give you an accurate answer.
Welcome btw!

have you had your car dynoed? Were you driving it when it came close to the ls7? A stock ls1 with a modest driver is not by any means invincable, especially with a well thought out and built sbc combo with the correct gearing.
Thats just my opinion.
What c/r are you running? What heads? What cam? I'ld like to know more about your combo.

Now, now Sonix. Play nice. I think the three threads should be "MOVED" to the theoretical racing board. ...where he can play with others who have imaginary cars.

I also would love to see a streetable 327 that ran 10.2. This guy can't give any specs on his engine except hp and 1/4 mile time. A really good driver once told me "Everybody has a 10 second car until they run 15's at the strip"
So... lets see a timeslip or dyno sheet. And btw, how old are you?

An old 350 will not rev faster than an LS1 ... PERIOD! The gen 3 engine has a drivetrain that is way lighter, and far more efficient. And I dont think a 327 will smoke both a 350 and an LS1...

A 327 could roll an Ls1 on top after around 90mph.. Depending on how the motors built.. but umm yeah.. Real 327's are hard to even come by.

I tried a challenge already, he's in arizona. I'm in louisiana though. Might be worth a trip to show him what a real car runs like.

No no... The built 355 is going in in two weeks. Along with the 3.73's, new tranny, and 150 shot of nitrous. I'm looking at about 430 hp on engine alone, and the suspension to hook it up and go.
I built the car from the ground up and its almost finished.

Wow...just wow. I'm at a loss for words with this post....
While you right with the bore/stroke comment it's minimal. You're still wrong about your average SBC revving faster than a LS1. But then again since you're running 10.2's you're vast knowledge is far superior than anyone elses.
BTW what was your trap speed on that 10.2 run?

what did you do to that 327 to make 430HP?? i have a 327 from a 1966 corvette in my car w/ 11:1 CR and when it was dynoed it only had 240HP at the rear wheels (i can post the dyno sheet - i'm not talkin sh*t). i can probably make that a little bit higher with some tuning. anyway, my engine is far from stock so i'm just wondering what you might have done differently to your motor.

a lot also has to do with the powerband. the LS1 has a very flat power band unlike some other motors with a fairly narrow power band so they can put down the power longer

stroke has nothing to do with how fast a motor can rev and don't give me the crap about side loading and piston/rod angles or lateral forces as those are going to be very minor unless you are running well in excess of 10krpms. at the rpms that most cars are running stroke doesn't effect it that much. there are many other more important factors involved. anyway the stroke between an LS1 vs a 350 is very minimal as is to already ofset the already minimal effects it would have anway
how can a 327 smoke them both?
what have you done to this 327 of yours anyway?

Am I missing something here
The first post was:
i have a 327 that makes around 430 hp and i want to know if it can beat an ls1.
Then we have:
Now correct me if I'm wrong but if a 350 is better than an LS1 and a 327 will blow them both away, why are you asking if your 327 will beat an LS1
I'd say that your 327 will smoke the 350 that just smoked the LS1 and after that you can smoke more of whatever it was that told you to make this post

Going on the basis that a stock '86 Camaro weighs roughly 3300lbs.... and using an E/T formula for guesstimating Horsepower... I think this guy's sandbagging y'all
Using this formula: hp = weight * (speed / 234)3
His car is making more like 615hp!
l84327, do you wear earplugs when you drive? 'cuz I'm guessin' that sound barrier "BANG" must get annoying after a while.
I tell ya what... I have a little Japanese 4 banger I'll run you with.

this is basically a +1 thread and a thread to vent your pent up aggression against newbs. also if those of you who are not members here and read the thread and don't want to join now, don't let the thread detour you because we only get like this against people who are like l84327, who doesn't know anything and he lied about what he has.
