hey guys i need some good advice i want my 86 lb9 into at least the mid 14's i got the 3.42 gears and thinking of going with the summit tpi cam kit would this mod bolt me mid 14's thanks

 

I would say yes, definitely, if and only if you can get some decent traction though. Get some slicks or drag radials. Just my .02

 

I'm runnin' low 14's on 245/50/16 Pep Boys Futura Ultra Z's and this was before adding the Spohn LCA relocation brackets.

You may not need gears. With a cam change I was running enough mph to be into the 14's easy but alas... my car was lowered and I was just starting to race so I never made it there
I'd suggest cam and headers, that'll do it. And ditch that stupid 86 computer chip, use an 88 instead.

 

i tried the g-tech and i ran 16 at 87mph lastyear i ran a 15 6 at 90 this year i got rid of the cat and put z rated tires on my car 2.77 gears suck

 

I run 14.6 Stock heads, cam, exhaust manifolds and intake on a 305TPI. Minor mods listed in Sig. My car is a 5-speed and came with a better cam than yours. A cam change will make a big difference for you. If you are able... do headers at the same time. The incresed exhaust flow will help out a lot with the new cam.


I have heads, cam and headers all coming very soon and all going in together ASAP. hoping for a high 13 from the Lil' 305

i have an 89 lb9 with 3.45 9 bolt rear(posi slipin and only one tires grabs) custom air intake with k&n, flowtech headers and y, no cat, stock 2 3/4 i- pipe, and flomaster 80, and the only other thing that was done is that i shifted the car manuel and held every gear to about 5200 i also have a 2400 stall coverter

and the last time i was at the track with nothing removed from the car i ran a 14.86 at 89.5mph and i could not get tracktion for $hit and the car was not runing right either

so i say it is definatly posible and have the peanut cam in my car
just do what i did

 

lastnight i just tried my g -tech with the new 3.42 gears i was really discusted i ran a 15.7 at 90 mph my ta only has 38 000 kilometers on it i find with my car when floored it sounds like its getting no air in it and the tranny shifts way to late like 5500 i might try manual shifting it at 4500 see if it makes a difference thanks

 

ya if you have a stock 305 even if you have intake and exhaust like me there is no reason to rev to 5500 i noticed that when i shfted at 5200 instead if 5500 my times were faster
i would say that you should shift at 5000

 

SO CHANGING MY CAM TO THE SUMMIT TPI CAM WITH THE SPECS 268 IN 278 EXH 050 204/214 420 442 112 DEGREES WILL THIS ATLEAST GET ME IN THE MID 14;S

 

IT SAYS ITS MENT FOR THE 86 305 TPI AND IT GAINS 40 HP AND ALMOST A FULL SECOND ON 0 TO 60
SO IT SAYS THANKS

 

At most, but further tuning/practacing can move you below 14.5

 

I went a best of 15.29 on a stock LB9 peanut cammed 305 by just adding a 3.27 BW 9 bolt and 225/50/15 GForce drag radials.

My goal is 13.99 on a 120,000 mile motor by this time next year, no juice allowed.

 

thats great time for that car can my timing be out is that why i'm not running a good time

 

It's an 86, it has the peanut cam. Get that cam out of there and you will see significant gains on even an all stock combo.

 

I have a stock 87 LB9 long block with 160k on it. I removed the TPI and all the Horse Sh*t. Installed a Holley 650 dp, MSD dist, box, coil, Heddman 1 5/8 LT headers, Holley street Dominator intake, dual 2.5 flowmasters 40 series, Holley blue fuel pump and a 4.10 gear. I think it will hit 14's with no problem. Just adding a gear alone makes a hell of a difference. If your budget allows go with a cam, exhaust and a gear. It will put a sh*t eatin grin on your face and 14's. I will be going to the track this summer and will post what it ran.
