Carbureted LSX forum - my new build,,,oh no another mustang

Ihave a 89 coupe mustang im building,,, just got it running sunday. The motor is a 04 6.0 motor out of a yukon with 110,000 miles on it, will be carb.. it has a glide with 4.88 gears. It has a Pa racing moly front end with coilovers,, it should weight around 2350 if the motor weigh's the same as my sbc that was in it... hopeing to take to try out thur night,,, right now gota get brakes working right.. heres a pic motor

heres some more pics

I want....

been lookin at timing plan for the msd box,,,, whats the best timing for a bone stock motor i may have put to much timing in it.... ive done been looking alot,, still not for use what to use
thanks for any help

Looks like a good start, whats the plans, goals?

well no big plans,,, its justa bracket car i race every week,,, prob winter time, might change heads and cam for next year...and put it on e85

20 initial, ramp to 32 all in by 3000. That will be a safe base line.

well the car ran great,,, best pass was a 1.48 60ft and ran a 7.009 at 96 mph thats turning it to 6000rpm shifting,,,, also im only leaving at 1800 rpm's because my brakes wont hold good,,,,, this is with a 750 vac carb with only 66 jets in the front,,, ill put my 800dp hp carb on for next week,,,,

And this has no cam i assume? That is fantastic man, small converter i assume?

Guess I'm gonna have to bring mine to you so you can get it straightened out.

i have a big converter,, just them dang manual mustang brakes,,, wont hold,, the converter before went 2700 with power brakes and will go 4600 on trans brake. this is a bone stock 110,000 mile motor,,,never had valve covers off..

Damn, i cannot wait to get one of the boxes and drop a cammed 6.0 in, that car runs better than the 7.1 my car ran on average, it is 3450 with me in it though. And it was a 6 speed.

chevy did somethin right lol

damn thats scootin.....but that motor would be a helluva lot cooler in that c10..

i have a 4.8 motor setting in my 72 chevy truck right now need to finish it up too,,,

it should weight around 2350 if the motor weigh's the same as my sbc that was in it... :eek: WOW....grats on the awesome time with stock motor. :cool:

anyone know if they weigh the same as a iron headed sbc? i going to lower the timing some and see what it runs.... then puttin the 800 dp carb on,,, any good idea's,, i dont care to try anything,,,, we will see


oh im a turbo buick guy i dont care to test anything,,, im not scared like most guys..... mm whimps...

im a type of person to get everything out of a motor with less,,,,,, like to see 6.5's with a stock motor,,,,any good idea's

Tune away at the track bud, get her dialed in with ET and a wide band.

i have my 800 dp ready for thur night,,,, im going to make couple passes witht he 750 vac then put the 800 on,,,,, and pull the timing up,,, been lookin all day for new tables

it should weight around 2350

:shocked: That is not car, that is a rail! Man, my portly Buick is jealous of the light cars.

oh i know how it was to run a heavy car,, my 67 chevelle when i was alot younger,, then got a grand national that was even heavier than the chevelle,,,

here was my passes i made sat, it was a race but reallyjust getting a feel of the car,,, im a bracket racer..
1st pass 1.51 7.05 96mph left at 1800
2nd 1.49 7.02 96 same
3rd 1.49 7.02 96 same
4th 1.51 7.06 96 left at 1600
5th 1.49 7.02 96 1800
6th 1.48 7.00 95 2000
not bad for the first time out gota get them manual brakes better wont holdany higher than 2000... ill be going thur to a test and tune so i can try some new stuff and ill post what i find out
my timing curve on them was


oh yes if anyone wants me to try something i will,,, we here all to learn more
0-500 20 deg
500-1000 ramp to 35
1000- on up was 35 deg

That thing is deadly at 1800. Three 7.02s! What kind of trees were you laying down with those iffy brakes on the line?

had red lights first 2 runs,,,then late next but 5.2's light then on..

20 to 30 package will consistently get it done.

well im ready for some test and tune thur night heres what im going to do with timing
500-1000 ramp to 38 deg
1000-4000 is 38 deg
4000-5000 ramp down to 35deg
then 5000 to 6000 stay 35 deg

what u think,, i shift at 6000. u wont hurt my feelings is u see something wrong,, i just wanted to try more timing

I will be surprised if a cathedral port headed motor likes that much timing, but your car is light. I guess we will find out when you test at the track.

whatd you do to be that light? im at 3200 with me in it and just over half a tank of gas. thats also with my laptop, and other lil stuff i take to track

well the mustang did not do to good,, the track was not to good tonight,,, plus it was hotter than last week 1.51 at 7.09 fastest,,, could not tell if it like the timing more,, cause it was spinning... maybe on race night will be better...

well heres my race tickets from friday race night
.522 light 1.52 60ft 7.111 i shifted early
.526 1.51 7.059 6000 shift
.520 1.51 7.06
.525 1.51 7.07
first round got dark
.494 1.51 7.067
.498 1.51 7.067

its getting better

That thing is deadly for a bracket car. What do you have cooling that thing off?

all i have is an aluminum rad,, and stock pump with no thermo... i have a sbc water neck on it..... this thing never runs hotter than 150....

Cam and nitrous on that beooooo.....

oh it wont be long before the nos goes on prob,,,, im still going to wait on the cam till winter, kinda still looking on what to get. been searchin on all the post's here and still cant make my mind up.... any suggestions,, its more of a bracket car than just all out nos...

Windmill , how ar you getting that big air cleaner under the stock hood? How is your motor mounted, cause with my AJE K member and a Victor Jr manifold I have to heve a low profile air cleaner to barley squeeze under my 2in cowl hood?? Id love to throw a 2 inch spacer on my 6.0 but there isnt more than a 1/2 befor I hit my hood, please enlighten:nod: And those 60 ft times are nice. what do you think youd 1/4 in? Also I see Team Z control arms but what kind of rearend did you buil up?

well the k member is from p a racing it did not have mounts when i bought it,, so i made them my self,, the motor is in there lower than usally. i set the motor as low as it could go,, i have a 1 1/2 inch drop rack. and also it moved back as far as i could go too,,,,, the breather is a 5 inch,, my hood is a 3 inch cowl it is diff from most too.....the rear end is a 8.8 with 31 spline axels and moser unit in it.....oh it would never make it ti the 1/4 to much gear.. if u neeed some diff pics i can take some...

thanks,, im lookin for alot better times thur for the test and tune..i had been running the 750 vac carb,, well i tryed my 800dp and it only ran a 7.11 so i took it back off so sunday me and wife was going to take it apart and my wife ask me why didnt i hook the 4 barrel up,,,dah dummy me the carb was on my 283 that was in it before i changed to the ls,,,, so it ran a 7.11 with a 2 barrel,,, i know most wont beleive me but it true so im pumped for thur to see what it will run....

Thats the best kind of suprise, your old lady must be pretty slick. Wait till you hit that car with some spray, youll be scraping the bumper:nod:

well we had a sorta good night heres the 2 best runs tonight
1.501,,, 6.984
1.497,,, 6.983 both at 97 still leaving at 2000 rpm's also this is with the 800dp carb with 70 front jets and 83 rear jets but i do have a stumle leaving,, got find out what it is.....

Good times man. What track do you run at?

i run at sandmountain dragway,,,, well had a real good night tonight, my buddies nova broke so they let us double enter my car since his broke beefore the race,, so he won the run for the money and also we won 1st and 2n place,,, so its been a great night,,, the car is dead on every pass,, i wanting to go to steele tomorrow they having a 2000.00 foot brake race since it rained last week,,,,,

Very nice and grats on the win. Sounds like you got a very consistent bracket car.

Thanks,,,, ill be goin to night to the 2000.00 footbreak race tonight,,,, maybe ill do good...

Good luck!

Well the motor like the timing,, i had it on 38 deg across the board,, 1.477 at6..94 at 99mph. im still leaving at 2000 rpm's.

nice mustang. Its definately a strong runner for a stock engine. I also like the old c10 as the tow rig. It's a lot cooler to me than the typical dually and enclosed.

i'm putting a 4,8 in the truck,,,, the mustang is for sale for 8,000.00... if u see anyone interested.

Tired of the stang already?

oh no,,, im ready to get my 67 chevelle going,, all used to faster et's too...
