Just wanted to encourage all the other 305 guys out there, see the sig.

Nice!

So I have a totally dumb (n00b) question. How do I know if I have an LB9 or an L03? I get that off the VIN or what? I bet there is a visual clue. I'm guessing I have an LO3.

N8MAN1068

awesome! can you post your timeslip?
what was your 60'?

i have a Lb9
113 heads, lt1 intake w/24lb injectors accell afpr, comp nx262, coated hooker comp's, th350....still need a stall, but damn this looks promising!

Acceld Z

You have an L03 judging by your sig pic. The big visual clue pointing towards an LB9 would be the presence of a TPI unit under your hood. The eighth VIN digit will be an F if it's an LB9 and an E if it's an LO3.

Cadillac

No TPI unit, 8th digit is an "E".

Thank you sir!

do you have best bolt on times before the cam?

I was gonna put a cam in my LB9 to look for 13's, but for the money and time, I want more than .90's. I wanna be in the 50s at least. O well, need more cubes.

sweet, i hate how ppl Put down the 305, they can put some good times as well

N8MAN1068, i tried to post my timeslips but the scan was too big, i can e-mail them to you if you want to see them.

NastyL98_T/A, i did the cam and headers first and it went a 14.8 @ 93mph. then i did the heads and converter and posi. needless to say, the converter did its job(1.93 was my best 60") and it looks from mph gains that the heads gave me about 40 horse. now its time for a cat back exhaust and chip burnin.

NastyL98_T/A

shweet. You've got the converter and the gear, need to get to the track on a good day so that thing will hook. I've cut a 1.76 60ft on DR's, all stock suspension in my '88. 1.92 seems a little slow for your setup. Track or weather suck?

I went 14.2 without a converter with about the same 60's as you.

Im wondering how much of a difference your cam makes than mine?

Im waiting on a home insurance check to come in so I can get me a converter. Thinking either a 2800 or 3000

ThirdGenFire

Sounds sweet there man. I am gunning for mid 14's here in Texas(thats a mid 13 sealevel). I have ported the heads, put a Crane compucam .440/.454, hooker headers and some other crap. I just added tires and some rims now need to buy a higher stall converter for it. Lets hope I can catch up to faster 305's.

TunedPort 335

--Ran a 14.1 @ 99.7 with a stock slipping 700R4 with 2.73's.


Now I just put in a built 700r4 with a 3000 stall, haven't brought it to the track yet but it feels much stronger. I can't wait to dive into the computer tuning, which should wake it up alot more.

Congrats!

well when i ran the 13.9s i was only cuttin a 2.0ish 60" because the track was really going away and i was spinnin pretty hard.

earlier in the year when i cut the 1.9 60" times, the track was great, the car would hook up pretty good, but i cant stall up much past 2300rpm because it doesnt feel like the brakes will hold it at that rpm, the car starts to creep. those 1.7 60" times seem pretty good, but compared to all the other cars i was against that night i was doing well, all other street tired cars i saw were only cutting 2.0-2.2 60" (except for the 4WD ford super duty there cutting 1.8s and going in the mid 13s) so if any of you guys can do better than 2.0 on street tires let me know what you are doing.

Wishmaster, my cam has identical specs to the LPE cam offered for the 305 (it is a hydraulic flat tappet cam). it seems kinda big but i think it is ok. the motor starts coming to life pretty strong at about 2800rpm, (which seems about 500rpm high) i'm not sure if thats because of the tuning in the stock chip, or if thats just how the cam is. but i do know it quits at about 5500rpm. my car may be faster with a slightly smaller cam, i dont really know. it would be interesting to do a dyno test and find the best cam for an LB9 with a stock intake.

FruityOne

1meanZ, you're combo is VERY similar to mine, though I don't have nearly so much stall as you, my stall is 2,200rpm on a rebuilt converter. Got the converter for pretty much free so thats what I ran.

Only differences between your setup and mine are 45cubes, LPE 211/219 cam, ported iron L98 heads, and I have a hooker exhaust setup. I ported/siamesed the plenum, ported the base, and am using AS&M semi-siamesed runners......okay guess there are lots of differences. I'm hoping for mid 13's with this setup. It would be nice to hit there. I'm sure with much better heads I could go lots faster.

Good to see you are getting such nice results from your work. I'm sure a tune would help tremendously.

i trapped at 96 with my bone stock 305....ive gotten alot better driving and have beatin quite a few turbo neons that run 13.8 in the 1/4....and i still have the motor untouched. some days it runs really great and sometimes it feels tired...then again theres 162k on the motor..nehow congrats on running 13s. its tough for the 305.

mikobu3

help me out boys

i did all that stuff to my 86 305 tpi with 20 000 original miles , comp xtreme energy 212-218 449-456 112 lsa , i bought there cam kit as well , ported and polished the 416 heads put the bigger 1.94 intake valves, ported the base , cai , mac headers with 3 inch y-pipe , no polution stuff , all new plugs , filters ect,,, 3.42 gears with posi ,

hooked my scanner up to the car it shows 2 codes ,, est , egr,
i also notice my blm;s are at 128 at idle and start jumping to 158 ,
anyways i tried out my g-tech and i ran 14.9 at 96 mph

i have all the chip burning equipment , but you really need to no your stuff to do that

Captain C

The 9.5 stall converters seem to flash to stall better. My old 12" was supposed to be a 2500 but I could only get it to 2150. My new 9.5" 2800 rpm Edge converter flashes to 2800 if I drive more aggressively than (How do I put this) cop avoidance driving techniques.. haven't been able to take it to the track since the new Probuilt transmission and Edge converter installation, but it feels really good!!!!!!

Hope to have my headers reinstalled today. I'm installing a 3 wire heated O2 sensor at the same time. After I take care of another small problem, the Prominator goes in. I already have it installed in my spare computer.......

mikobu3, go to the track and get a real time. G-techs are usually kinda close, but i wouldnt get too bent out of shape untill you run it at a real track and get a real time for it. then let us know what is goin on.



Captain C, tell me more about this prominator you speak of, i dont know anything about them

BORLAZ06

old g-techs are usually off by +.3...and the mph is waaaaay off..

bnoon

If you practice on setting up a Gtech at the track, you can usually get much closer than 3 tenths. The MPH is off because at the track they average your speed through the traps (are they 50 feet apart???), the Gtech measures your peak speed at the very end of the quarter mile traveled.

mikobu3, I would spend some time data logging if I were you. Active data through a full throttle run will help you figure out where your car is running the richest. I had to start by reducing the first three MAF table values by 20%!!! This is on my 224/224 .465/.465 Summit cam, so I'm sure you'd be a bit less, maybe start with 10% or so and see where you are. If you can't scan active data during a WOT run, get to a dyno and take a couple of chips with you. You may also need to reduce your fuel enrichment vs. RPM during power enrichment mode... I think I also had to drop those table values by 10% down low until the cam "came on" and my dyno showed a tiny bit lean at 13.8:1 ratio. I've since added 1% at those lean values and she seems to have picked up just a touch better throttle response.

I haven't taken my car to the track yet (simply because I think it's embarrassing to run slower than my modified Contour could run), but I did dyno at the Midwest All F-body meet. Judging by Josh's fairly stock '88 that also dynoed, I gained about 50-60 HP and a flatter toque curve from SLP runners, the Summit 1104 cam, no emissions, a single 2.5" Dynomax muffler, and the custom tune. Not bad for not having headers!!! My HP was 192 at the wheels, which is almost what the LB9 had at the crank in '86. My torque was 242 or 247 at the wheels... I don't remember for sure, the sheet is at home...

mikobu3

no tracks here ,, next year i will take a 4 hour trip to sparta ,

car seems fast as hell , i should of bought atleast an afpr , maybe that will get the car running better , i no its lean , as for g-tech it is 5 years old and almost everyone in my town used it , i think its on its way out ,, i had my best friend try it out with his 04 honda accord v-6 with 240 hp , he ran 15.00 flat with a manuel tranny ,

for this year i will leave the car alone , maybe this winter i will read and read some more on theses chip burning techniques

thanks
