Default What cam and heads combo is proven for 10s on stock bottom end LS1s?

Other than Cartek's X package, which has gotten 2 C5s in the high tens and many more in the low to mid 11s, what is the most battle tested, proven heads and cam combo, that has taken a stock bottom end/cubes (LS1) into the 10s on motor only? I know how tuff 10s are on stock bottom end LS1 on motor only, but know several have done it. That being said what combo has also pulled off consistent low 11s?

Please be specific about whose brand heads and what specific cams and specs.

Thanks in advance.

My GTP heads have pushed me to bottom 11's a few times, but can't seem to break the 10's yet..

I had stage 2 LS1 heads, with a 226 590 lift cam..

I switched to stage 2 plus heads and right now have the same cam. I went 11.15 @ 124 on friday with first shakedown passes. I can only hope I can break into the 10's..

I also have a reverse split cam I think I'm going to put in and see if I get any gains from.. We will see.

But To answer your question,, I've seen a bunch of GTP cars running very well.. Jason99T/A car. Georege C had a 10sec ride before his bog bore with just heads and cam and stock bottm end..

ONYNXSS with ARE HCI and A4 went tens (~3400 pounds)

Rich with ARE HCI and A4 went tens (~3350)

Terry B from MMS went tens. (~3200 I think)

George C went ten's when he had GTP heads/cam (~3200 I think...)

Raughammer went 10's with MTI but had a rebuilt
bottom end for his best 10 second run. (not sur eon his weight? (3200 maybe?)

Cartek has a couple C5's in the tens but no F-bods AFAIK. (JS is close but not there yet, 11.1's I think)

That is all I can think of off the top of my head.

I would look at the mph packages are running in combination with their raceweight. That will give a good idea of a packages potential ET. (converter, gear, slick/tire type, chassis/suspension setup, 60 foot etc all influence ET a great deal.) For example on street tires I ran a 12.0@120mph. On slicks with a bit of suspension tuning (airbag etc) I went 11.30@122mph on ET streets (1.58 sixty)
I didnt magically add 80RWHP I just hooked <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Cheers,
Chris

My point is that weight and DA are important, but there is no magical heads and cam package alone that will put you in the 10's with a 346 CID motor without everything in the car being set up correctly. I'd say that the cars running 10's about 85% to 90% of that is the car set-up and the rest is in the heads and cam package. As long as you have a reasonable level of power and can get it to the ground properly the car will run the number. OTOH if you have 9 billion RWHP and can't apply it properly you won't run the number.

LGM H/C package F-car went 11.06; she (driver) was going to get a bigger converter and shoot for the 10's. I'm not sure what the status in on that, though...

WEIGHT is the biggest factor--->PERIOD!!!
When u weigh 3300lbs or less its not too hard to click off a 10 in a properly setup car.

JFM's (Dad) setup went 11.04@121 with the Absolute Speeds heads and cam combo.I FULLY expect a ten second pass this Friday at the strip. J.S. to say it's not "to hard" to click off a 10 second pass at 3300lbs sounds like a bit of a discredit to someone who has done it at that raceweight.I agree weight does keep things in perspective though it = free HP.

JFM,How do I descredit ANOYONE with my statement?
U tell me,How many 346 HYD. H/C cars out there to date have run 10's at 3450lbs or more..
I can tell u NONE!!!

My statement is not a knock on anyone.
Its a reality,a car thats 3300lbs or less has a very good chance at running 10's with ANYONE's H/C with a good tire and susp. setup.

And no one will convince me otherwise.
Angies car is 3050lbs,THATS light...
Your dads car 3300lbs again LIGHT...

But actually its a credit to u both for running so well.Angie runs a mild setup.Your dads isnt that radical either.This shows that u dont need fancy smacy stuff to acieve a goal.

Just a good set of heads (which u and angie both have),A good cam,some susp work along with proper tuning,gearing and tire and a LIGHT car will reward u with a 10 Sec slip.

Most guys know this on here already,Maybe I'm just bummed that I'm still a PORKER <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Default Re: What cam and heads combo is proven for 10s on stock bottom end LS1s?

Here's my dilema that i'm struggling with. I run et streets and skinnines on my 98 c5 with hal shocks, FLP LEvel IV tranny and PT 4000 stall and Getrag 3.73s. I run mid 11s with only 375rwhp with my old style cartek stage II heads and cam.

It seems to me that my new stroker engine will make so much power that i won't be able to hook up with et streets and really don't want to use full hooiser drags and therefore, the baddest azz heads and cam will probably run almost as good if not better ets than the MTI stroker, b/c i won't be able to put the power of the stroker to the ground.

FOr thousands of dollars more, maybe makes more sense to go with LS6 stage II MTI heads and X1 cam. What are your thoughts?

You are going to drop ~20K on a package and not run a good tire LOL? <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

I think you will still hook on the ET street personally. If you cant hook on it step up to a 27 inch QTP.

Did you ask Angie's weight? I believe it is 3000 race weight. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />
Not many, if any cars in the 10's with a 346" that you would want to drive around in. I hit a 10.992 @ 123 with a 1.48 60ft. when I pulled my carpet out to have my cage installed. DA was -500 and I'm guessing weight at 3380.
Early Stage 2 ARE H/C, A-4, Strange 12 bolt 4:10, BMR Trac-Pac and K-member, Bogarts with ET Drags and ET fronts.
When the cage and lt.wt. carpet is in I hope for consistent 11.1x

J.S. it just seemed like you were implying that if your car weighs 3300 lbs your a lock for a 10 sec pass.It's funny I was talkin with Dad and he stated exactly(almost) what you said about how many 3500lbs car are in the tens.He of course said as you did zero.3545lbs is that with you in the pilot seat?

Jr believe me I know it takes ALOT more than a light car but it sure does help <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Yep the car was at 3545 w/me in the seat,Now I'm not sure?I will find out in about 2 weeks.Hoping for 3500 even with me in the seat.

Its all good JR.....
Now get those 10's with your Dad <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
