Carbureted LSX forum - Stock lq6 carb dyno

Hi guys and girls. I just got my truck dyno and wanted to see what you guys think. Its a 91 s10 with a bone stock lq9 with a 750 hp and stock 700r4 with a shift kit. The rear has 342 gears. The truck made 345 whp at 5500 rpm and 370 ftp at 3300. Just wanted to know if that is about average or not thanks. Stock converter and edelbrock/msd timing controller with the pills.

Sorry lq9 lol

with what pill? we all neeed to know....

# 5 msd pill and I used the dual plane intake and shorty headers 1-5/8. Just forgot the write that in my first post

Very very nice, with a set of full length headers and a actual adjustable timing box and custom timing curve, there is plenty left in it, not to mention, is the carb tuned spot on?

My 2001 3/4 ton with lq4 dyno tuned with cat back, modded air box with k&n through a 4l80 and 14 bolt made 292 rwhp. You have. Ore left in that engine with a few other parts swapped and a tune if you want more. I say you are making above the norm slightly for small headers and not having a spot on timing curve.

Yes the a/f was at 13.0 12.9 at wot. I would like to do a small cam. Maybe the hot cam or 224r something like that.

Would the fully programmable msd make that much difference for timing.

msd 6010,hook up the laptop and change the timing to what you need,don't forget to pull the pill out before you shut it down or it will boot up to the pill thats in it and you will have to start all over again,
345 rwhp is excellent for what you have,my guess is your tune is getting very close to where you will settle,remember small reversible changes towards a great tune,choose carb or timing first then grow from there,too many people go backwards and waste time by getting ahead of themselves,personally i go afr first then start the timing bumps,all in all you are way ahead of most with those great numbers,wow,,,

What would you guys recommend for a cam for the street that will make more power yet be a good daily driver

how many miles on the motor...

easy cam choice for daily driver with good power .551 lift corvette cam,great idle,great all around power down low thru 6000rpm,should pick up an easy 40hp,

Motor has around 60k on it. Corvette cam you mean 04 zo6 cam?

yes one with about the same specs,gm tested and mother approved,its a great all around cam and will respond very well if you decide to hit with a bottle down the road,its a proven performer with a smooth idle and one of the better factory grinds,204/218 duration @.050, .551/.547" gross valve lift, 117 LSA.this cam profile or thereabouts is made for most of the ls family of motors and everybody has their version/copy of it,

I say a hot cam, will give it a nice idle and bump power and the power band. Bringing rpm over 6000, they can be had new for 300ish if I remember correct.

Yeah it's a toss up. Both of need a valve spring upgrade. I guess it come down witch one is cheaper. Down the road I plan on hitting it with 150 to play with some guys on the street lol. Do you have to change pushrods with either cam?

Can you do the hot cam with out a valve spring change? I don't think you can but it would save me some work lol.

Can't you use the z06 valve springs on the hot cam? If so they are only like 60 bucks New from your dealer. Someone else will have to chime in to verify tho.

I think the z06 cam has too much lsa for a Carb engine doesn't it?

It doesn't have too much, just won't be an extremely large power gain. But it will boost his power some and still pull lots of vacuum and idle good.

Oh and plus he wouldn't have to invest in A stall converter. Saves him some money there.

Yep, nice little cam.

Maybe the sdpc truck cam???

I put it in my 5.3, motor only ran on the stand though. Idles good, not sure on power gains. I used the blue springs from lingenfelter

70 bucks for the set

I think I might go with the hot cam. I think it would make more power then the zo6 cam. The. Down the road I will put in a 2200 to 2400 converter. Now I just have to find a used hot cam lol. Let me know if anyone has one thanks

Just keep a look out, a 3000 converter would be best just because you will wish you did later, lol.

Yeah I hear that. There is nothing like the sound or a car with a high stall lol. It just sounds fast. Thanks for all the info.

One more question. If I do the hot cam or z06 cam Will I have to change my push rod length? My heads and block never been decked or shaved.

Not likely but you always measure anyway just to be safe. And 3000? I don't consider that high, putting a 4800 in my TA, lol.

i picked up 2 tenths and 2 or 4mph(cant remember)going from a stock truck cam to a 02 zo6 cam in the 1/8...went from shifting at 6000 to 6500...this was a bone stock 03 lq4 with a dual plane performer intake also.

That^ guy had inspired some mustang LS swaps. Lol

Ok thanks. What trans do you got? Want to sell that 3k converter lol. I have a 700r4 30 spline.

I have a chance to get a brand new xr269hr comp cam for 150 is that a good choice? I know it's alittle small but for that price I think it's worth it.

Adjusting your combo around a bit to fit your budget isn't a bad thing.

Do you have to change the valve springs with that cam? My heads are stock 317s.

Pretty much always have to swap springs. Prevents valve float when abusing the engine and allows for the higher lift.

Was waiting for you to chime in lol. Is the xr269hr a good choice? I can get it nib for 150 and just use the yellow ls6 springs

No idea, cannot find the specs.

Most guys say not to use the yellows with aftermarket cams. Even the small ones. They say the lobe ramps are too aggressive for the yellows. But, I am just repeating what I have read.

216/220 525/532 114 comp cams

Would work, but far from optimal, I say no, find a better grind.

Maybe the sdpc truck cam???

I have that sdpc cam in my lq4. I am not sure of the power gain but the motor is in a 4x4 burb and it pulls pretty good. It has great low end. I have my rev limiter set at 5000 and it is still pulling strong at 5. Nice idle too. I have had it set at 700 with the carb and it ran good.

Try and find a used TR224 on a 112. Would out perform a ls6 cam and hotcam too.

GM ASA
LPE GT11
CheaTR.
All excellent cams for a 6.0. Tq everywhere. all pull hard in a 6.0.
Brian Tooley dual springs are some excellent springs. I installed a set in a friends car not too long. quality spring for the price. Dont cheap out on springs/pushrods. Get the good stuff if u plan on beating on it and expect some longevity and reliability.
