Not bad, my simulator was off by 1 mph and .1 so i am pleased for a gay 2.71 gear... rt..... .3572 60ft.. 2.1995 1/8... 8.467 mph.. 89.78 My previous best was a 9.0 at 81 with a smaller cubed motor, i wanted 8.3 or as low as 8.2 but hell, i was too ***** to launch it being afraid to break the T5 or 7.5 rear, i have a T56 and a dana 44 rear in the works, i think ill go sub 8s with no problem then.

Nice 1/8 MPH trap speed, should be good for 7.80's or quicker with hook.

Thats what i thought yoo, i think as low as 7.7 if i get it right.

man, with the trash talk you put out on the street racing forum and ls1tech.com, i thought you'd be quicker than that, lol! j/k...but for reference, my car runs 7.9's in the 1/8, but at only 84mph, so your mph is good for far quicker than that. hurry up and get that t56/dana44 in the car so you can start beating on it! seems like a stout contender though.

what the stats on your car ZONE89RS??

Its all on my Fquick acount if you wana see it.


Nova, i know what you mean, i KILL on the big end man, it just takes a second to get rolling with this tall gear, i think it will do some real damage with the 3.73 in. I keep pulling great in 3rd and even 4th gear just keep going man, it will be interesting to see how quick it is with the gear in, i have estimated about 450 flywheel HP.

i did a 9.6 @ 65MPH with a close to stock 305 TBI with a drag strip built 700R4 and 2.73 single tire fire, is that OK??? thats only one run, and letting it shift by its self (i didnt rachet the gears)


react .1961
60ft 2.2399
330ft 6.5879
594ft 8.9389
1/8 9.6328 @ 65mph

BTW time slip

How big of an engine are you running? The reason I am asking I just got a 91 with a 355 with 12.5 comp pistons, and a roller cam with a turbo 350 that I have not been able to test yet. I am so curious as to how quick it might be. They have taken all the interior out execpt the door panels and carpet. Installed an aluminum dash with no console.

305 TBI


that time was the whole car, even with my worth less boat anchor speekers in it, granted the 305 has some bolt ons but its nothing major

Custom Burned Prom
MSD Blaster Coil
Blue Streak Cap & Rotor
Accel Wires
A/C Delco Rapid Fires
No Emissions
Full 3" Exhaust Flowmaster 80 (no cat)
Open 10" round 4"high K&N Breather
Factory Restrictions Removed Out Of TBI
Drag Strip 700R4
Still running stock manifolds (my headers look pretty in my gagage)
Stock Size Street Tires
2.73 Single Tire Fire

BTW 1st time it been down the strip

You guys would be better off starting your own threads...

thanks for the help

Well, you will get a TON more responces than using a basically dead thread. Good luck with it!

!!!!!! Thanks for replying on mine

Very nice MPH! I think you have 7.7's or 7.6's in it, my car does 7.8 at 85 with a 1.7 60' for reference.

Sweet, i did build this thing for 450ish HP, so i dont see why not. I will let you guys know wheni do the swap, will be a while with my first born on the way by april.

nice times! the cam you are running...is it the xr288? or something similar?

I dont know the name of it, it is hyd roller, 110 LSA with .520/.540 lift, 236/242 dur @.050.

I have 1.6 RRs on the intake side, makes it .564 lift i think and might replicate 238 @.050 on the intake side.

theres ur cam....thats the cam i plan on putting in my 385 HSR
----------
With good traction I think you will be good with 7.4-7.5 range in the 8th....its good for 500+hp at the motor

We will find out! I would be more than satisfied to go sub 7.5s, i would be extatic.

hopefully the 10 bolts can hold up

Well, i am removing it in favor of another 10 bolt...a dana 44. So it should be ok.

Where can I get a dana 44 from??

Honestly, the one iscored was luck, verry few have them, there were produced in 90-92 i believe from GMPP devision as a replacement, hard to find now days, hurts me to think how many might have gotten tossed into a scrap heap.


Just gotta look for them, this one was the first i ever heard of.

not too bad. thats exactly the same mph, ET, and 60ft i got out of my hotcam only LT4 Vette in the 1/8. in the quarter my car did 12.7 at 114mph, so if your top end is anything like mine, thats about what you would turn also

So what gear did you have in the rearend?

What rpm are you shifting at?

From 1-2 i shift at 5500 because the trans wont let me shift to second any higher, wierd...2-3 and higher i shift at 6000, but i need a ign module so i can see 6300 or so.

I figured that cam would be good to 6600-6900. Maybe just needs lighter valvetrain like beehives.

I have a guy with everything i have in the same combo and he is shifting at 6300 and smacks a rev limiter at 6500, if it was a 350 and not a 383 it would go higher.

http://www.airflowresearch.com/chevy_dyno.php scroll down to about halfway on the page and look at the 8-433-8 dyno

....And with 1.6's on the intake it is .555" lift. .555/1.5x1.6= .555"

Yea, thats what i meant, i get cams mixed here and there.


89formula, i have seen those #s before, see where it ends at 6000, it would typically push a little further before shifting in a car, right?

if you are asking if you want to shift a lil later than 6000 then yes

Yea, thats what i thought, i wanna get the HEI upgraded and see what happens.

stock 3.45s

Awwww, i wish i had atleast that already...

believe it or not, these gears suck with the LT4 engine. after the hotcam and retune, it runs out of breath at 6800rpm (500rpm more than stock) and with the 3.45s it takes FOREVER to rev up. i really need something in the 4.xx range

Man, 3.73 or 3.90 is not bad. I had 4.11 in a formula(95) with only RRs and cold air go 8.7 in the 1/8th and i was in 4th gear, so with more motor it is not enough gear really, it is ok for a bolt on LTx in my opinion but that is all.


MY car would love 3.42s, but 3.73 is what i will be happy with for sure.
