Re: 305 LB9 are slow bull
My 305 is not fast , As the car sits it is a great cruiser it looks and sounds great . If the car had 100,000 miles on it i'd put a bigger motor in it.
But thats not gonna happen .

Got me ,
I was thinking hater guy . Unless you sink a mint into it , This motor is probally better off left alone .
I might trade mine one day for a built 3rd gen ---we'll see .
It sucks having a car that you really should'nt put miles on. .

Re: 305 LB9 are slow bull
why not? it'll take the miles, hell my 305 (albeit the high output model) as if that makes a difference, doesn't have many miles on it 42k now, but its been abused, sat for a long time, has some very bad noises coming out of it, leaks a ton of oil, rod knock, and tapping lifter, runs rich as hell due to the q-jet, but all in all i love the l69 and lg4s, i love the q-jet, i think they're great, if mine ran great (even close to death it still runs, started it this morning) i'd have no complaints, and i've seen l03 cars well into 300k before they had work done other then maintenance, everyone says they're terrible, but they last forever.

Of all the threads you could post this in, you choose this one. Make your own thread and ask man, instead of just randomly posting in someone elses.
The bore has nothing to do with rod and main bearing sizes. You need stock bearings unless you have the crank milled down due to wear.

Re: 305 LB9 are slow bull
I have a 305 TBI (92 RS). Bone stock except the air cleaner. Doesn't need to be super fast in a straight line. Goes like a bat out of hell on an autoX course, but that is more suspension, brakes, and tires. This is what really bugs me, is all the people who think straight line speed is the end all be all... IF they race, it's a straight shot for 1/8 or 1/4 mile. Great. I respect that. Or on the open road... take it to the track bub. LOL. But now you throw in a slalom and a hairpin with maybe 200 foot straights tops, and my weeny 305 is riding your *** or you are looking at my times and thinking "WTF!! But I have a blown 496!!". Hehe. Depending on what you do and how you play, a 305 may be just the ticket. Since I run sanctioned races, I can't swap motors to something more robust unless I am willing to bump into modifieds, and then I'm looking at having to butcher my car to make it competitive. As it sits now running ESP or STX, it does just fine. It's too bad people can't respect that, but oh well!
That said, the RS is sitting in teh driveway next to a Z28 with a bit more juice, LOL (L31 350, HSR, etc). Just for those "I don't want to be slow in a straight line" moments.

Re: 305 LB9 are slow bull
And you'd get crushed around the track by a 350 car because of those little straights, not to mention the fact that the 350 car will have better suspension and gear ratio over a 305 TBI base model and beat you around the turns too.
A 305 TBI is a ticket to nothing but the showing of a 350's taillights, plus 90% of the rest of the cars/trucks on the road today, lol. Doesn't matter if it is auto X, 1/4 mile, or a trip to the store, you'll always be behind. You can all defend your little 5.0's until your blue in the face, but facts are facts, and mod for mod, the 350 is going to win once the talking stops, and the driving begins.

Re: 305 LB9 are slow bull
Dude, if your talking about Sojer, you need to read this whole thread. He has already said he types like a tard on purpose because it is how they do it in Detroit with their wonderful education system, he has been offered help numerous times and never takes it, and he continues running his mouth with lies and BS. No, I was never in his shoes once.

WOW. Talk about trolls. ROFL. You missed the point. If I go over 5.1 L, I bump classes. If I go with a motor or engine components below the intake that were not available on my submodel, I bump classes. WHY would I want to do that? ROFL. Wisest money is in brakes, tires, and suspension, NOT the motor. Not to mention, AutoX is 80% driver and 20% car. Just as an FYI, I have beaten cars I by rights should not have been able to touch. Because the 5.0 rules? Hardly. Because I have been driving for 30 years. Autocross is about car control, not speed. Go ahead and try to come out of that hairpin with your foot slammed to the floor to take advantage of that 350, and you will be backwards into the grass. That should help your time, LOL. Hell I've beaten my fair share of Vette's because they tend to scatter cones everywhere with their rear ends. You can't romp the throttle the way you seem to be thinking, or you won't stay on the course! Smooth inputs. All other things being equal, yes, duh, a 5.7 will beat my car (pretty stupid to think it won't be faster with a 5.7, but in the new class, it means MORE money and MORE mods to get competitive again). But there is no way a 5.7 with a stock or poorly built suspension will clock better than a 5.0 with a stock motor and purpose built suspension in autocross. Being able to keep your car's speed up around the turns and through the slaloms is the key. Try racing against a stock Miata with a 5.7 and a stock or crappy suspension and see what happens.
In STX I run with 5.1's and below, mostly. ESP, all V-8s, I like the challenge. Obviously in STX I need not worry about 5.7's anyway, for the most part, they tend to run F Stock or ESP. LOL.
Are you assuming my SUSPENSION is stock? Bad assumption. My MOTOR is stock.
Good grief. I said the 5.0 is slow, and also have a 5.7. So freakin' what? You are just as bad as the OP when it comes right down to it... Jeebus! LOL!

Re: 305 LB9 are slow bull
That I agree with. You can pick up an L31 350 long block for about 1800-1900, new. Get a vortec TPI base, or a vortec HSR, and you will be in a much better place.

I know what auto X is about, but I feel it is more 50/50 with car and driver, because without a good car, the best driver in the world isn't gonna win a thing. And I know how to drive thank you, I didn't need any lessons from you about throttle input and so on, lol.
And NO, I am nowhere near as bad. I don't lie, and I can build an engine or swap an intake, and have it run right when I'm done.

Re: 305 LB9 are slow bull
Dude, I don't know the damn class rules, chill out! I know the sport, have been to them, and have lots of friends who do it in their Subarus, but I don't participate. Therefore I don't need to clutter my head with the classes and rules. You really expected me to just know that you couldn't use a 350 in your class? When you said more robust, I was assuming you meant bolt on parts or engine mods, I didn't think about a displacement cap.

Cool enough. My original point was simply that you don't need a 350 in some styles of racing, to be competitive. Of course, it can't hurt. You should try it, it's a blast. You rarely get over 50 or so, but that doesn't make it less fun! As far as the driver/car ratio, we had a novice come out in a stock Altima and WHOOP the novice field, which had a few cars being raced by other more experienced drivers (dual driver cars are common) and were prepped for autocross to one degree or the other. Shocked the sh*t out of a lot of people, the guy with the Altima was just a natural. If you ever try it, let an instructor run your car. You'll be blown away by how much faster they get through the course in your own car. ;-)

Re: 305 LB9 are slow bull
i have a question......if his car is that fast should i just sell my s10 with its 355ci v8, 500 plus lift comp cam, disc 8.8 rear, locker, headers, true duals, flow masters, and full man valve body and take the air cleaner off my 305 firebird daily driver with 2.73s and open rear so i can get 20 mpg and out run the new zl1s? and a better question is why are all of yall fighting with each other now.....go back to talkin smack to the 9 sec 305 car that was funnier. normally i would say dont bash him this is a learning and help fourm and i could see him saying oh ok sorry guys i dont know much about cars trying to learn so let me get a time slip and then ill ask more questions but the way this is goin yea im good. bash away my fellow thirdgeners.

The bore has nothing to do with rod and main bearing sizes. You need stock bearings unless you have the crank milled down due to wear.

Don't need a Moderator. People just need to STOP POSTING & it will slowly work its way down the list of threads & disappear by itself. It is everybody constant posting of "Close!" that keeps it alive.
