bad news 305 vs ls1
so i took my car out to race some guy in an ls1 z28 camaro and it was a little chilly. about 58 degrees f. so we line up and go... he just leaves me and im just spinning and tail going to the side a little... i start catching up once my car goes to second (had the car on d) but when it got to third i was at least 4 cars behind and climbing at about 90 mph he lets off. then we do a u-turn and this time i went easy on the gas in the launch and the tranny kind of shifted to second right away so again i have to catch up and i do a little but he lets off before i can even get anywhere near. i get out shake the guys hand and all. then i check my tires. my right rear passenger tire is a little low. i go to put air and its at 15 psi while the rest are at 30 so i also put it at 30. so that was most of my traction issue. then some guy in a monte inimidator wants to race so we do. im thinking my traction will be good so we race and i smash the gas pedal all the way down and the revs go up but the car isnt going anywhere and monte is already halfway gone. so yeah i lost then we did it again and this time i go easy on the gas and i get at least 4 cars away and still pulling all the time. i dont like to shift up because i always go to d right after 1 i think my shifter is bad or something so i just put it in d all the time. i know that is the better way most of the time but with my mods done the car feels like it pulls up to 5700 rpm and in d it shifts automatically at 5k

Re: bad news 305 vs ls1
yeah it was stock and automatic. im putting my car away though cause its getting cold and it should be ready by spring. ill get some suspension work. i also lost a lot of compression with the 350 heads so maybe ill get a supercharger or turbo whichever costs less until i blow the 305 or get enough for a better motor

Re: bad news 305 vs ls1
Nice runs. If you run the ls1 guy again just beware if he added any mods. I saw a full bolt on ls1 go 11.9. Yeah id say the respond very well to mods.

Re: bad news 305 vs ls1
yeah i wish i could afford an ls motor they are awesome but i would get a 6.0 truck motor i hear they are pretty strong that way i can supercharge it or something. too many imports are out right now running 12s making fools out of most guys in mustangs and camaros. at least the younger crowds because all the faster camaros and mustangs are usually guys who only let the beasts loose at the track or very rarely. at least out where i live. i dont know about anywhere else.

Re: bad news 305 vs ls1
I had a stock heads cam Ls1 in a 98 t/a that would run 12.40 withh exhaust gears and suspension. LS1's are sneaky, traction is the key on the street, few parts and some tires and you'll be giving them a good run for their money. Good luck with your build!

Re: bad news 305 vs ls1
Did you have 4.11's? I ran 12.8 at 109 with just exhaust and lid with the stock 3.42's. With 4.11s and tire I bet I could match your times. I want to get them but it would probably be catching rubber in 4th lol. I also enjoy saying my car can go 165 mph ahahahaha

Re: bad news 305 vs ls1
Have you ever had that 305 to the track? A 305 with just heads doesn't seem like it would even have a chance against an LS1. My cammed 305 with headers, exhaust, intake porting, and stripped down engine bay with no AC did a 14.3. An LS1 is a 13.5 car all day long and they are VERY stout up top. Sorry if I'm being ignorant...I don't know your car, but it doesn't seem like you'd have a chance with that set up.

Re: bad news 305 vs ls1
What shape is your suspension in? I used to have lots of trouble getting traction after my car got tuned. I replaced all four shocks and struts and that made a huge difference in the traction department.

Re: bad news 305 vs ls1
it still amazes me just how well those lsx motors run. it is for sure on the list of projects down the road. but i never could have built one the way i built my 383. couple hundred bucks here a grand there.

Re: bad news 305 vs ls1
I think it all comes down to the fact that they were very underrated, since most people go strictly by market ratings.

Re: bad news 305 vs ls1
im sorry guys the ls1 had AFR HEADS! AND TO TOP IT OFF SLP LID INTAKE, AND THE SLP LOUDMOUTH EXHAUST. Not very loud though. btw i found out just recently i got him to spill the beans. i think the kid didnt know what he was doing he should have been a lot further away from me. boy is my car slow. im thinking carbd 383 or something soon. i want to prove that ls1 isnt the only way to go. which is what everyone is telling me. besides its too expensive to get one swapped in. i cant do it myself either.

Re: bad news 305 vs ls1
Hmm. My dad has a 2002 SS/SLP 345hp auto and It runs great. If I had a 305 there is no way I would run that car. The same set up that is in my Camaro now is what was in my 78 T/A and I walked him pretty good and my Camaro is lighter weight so it shouldn't be a problem now but A mild 305 running with an LS1.... I would think that would be suicide.

Re: bad news 305 vs ls1
The slp pack actually puts down the same hp as any other ls1. Base Ta/ws6/firehawk/SS/z28, doesnt matter. The ratings were just for marketing and all ls1 cars will dyno 300-320rwh stock, which is around 350-360 at the crank. My buddys stock z28 actually dynoed a bit higher than my ws6 car haha.

Re: bad news 305 vs ls1
also 01-02 ls1 dyno higher then the 98-00 because of the ls6 intake and better profile cam. some 02 ls1 come with the ls6 block, which for some reason dyno higher then the ls1 blocks.

Re: bad news 305 vs ls1
Ls6 intake makes a difference but the 98-00 had a slightly bigger cam. Either way an ls1 = an ls1. Differences are probably in the dyno itself, all have around 350hp

Re: bad news 305 vs ls1
one of my camaro buddies said he saw under his hood and he saw AFR engraved on the heads so it does have them the only thing is he doesnt have the right intake manifold to feed the heads and probably isnt properly tuned either. that or the kids a sandbagger cause he was trying to race my buddy for titles but we said no and went home. well all i know is that car is fast and nice and i wish i could have the money to make my car run with ls1's i know i spent it the wrong way instead of dropping 1500 on the 305 i shouldve looked around for a big block or something better like a built 350 and spray it or something.

Re: bad news 305 vs ls1
ummm...an auto would be better for turbo cars since you dont lose boost between shifts. idont think it matters much with a supercharger since its based off the pulleys. i personally hate autos so id have a stick either way.

Re: bad news 305 vs ls1
Yeah back when I had my full bolt on l98 I got destroyed by a 99 firehawk. Not sure how a 305 would even have a prayer. Guess its mostly the driver and if the ls1 cant hook its over from there.

Re: bad news 305 vs ls1
haha my buddy just talked to the kid and told him if he was selling it he said yeah hes selling it for like 9000 dollars the kid showed us receipts of what he has which is suspension, heads, and slp exhaust. whoever bought him all those upgrades spent like 7k on that car now i know for sure he was sandbagging that night. maybe if my friend buys it i can put up some videos and pics of all the goodies in it in case any non believers here. he also told us he has a dyno sheet of the car and it pulled like 370 hp at the wheels but i have not seen it yet. man i was so outclassed that night. oh well..

Re: bad news 305 vs ls1
Bad suspension can be a good thing, a buddy of mine had a late 70's bmw with the struts that came on it from the factory. He could side step the clutch at 5 grand and the car would hook violently almost lifting the front tires off the ground.

Re: bad news 305 vs ls1
this is what a loudmouth exhaust sounds like on a stock motor
http://www.youtube.com/watch?v=_75vS...eature=related
this is what a loudmouth exhaust sounds like on a cammed ls1 ( varies on how big the cam is)
http://www.youtube.com/watch?v=MgK1WvBi12A
my friend has a mild cammed (228/228 .581/.581 114) 02 ss with loudmouth exhaust and it super loud. its louder then my cammed ( 232/234 .595/.598 112 lsa) 02 ta with a off road y-pipe and 3inch cutout with a resonator
