10 sec 6.1 ?

ok i know i asked about the turbos on a 360 before but asking doesnt hurt:read2:

can this be done ? no stroker , no nitrous , no blower , no turbo

stock stroke 6.1 , carbureted , pump gas , 10sec

1973 duster 3340lbs , slicks ,904 trans

The only issue is making the power, so, what parts are needed for the 6.1 HEMI to make that power?

Cams are limited, head porting would be the next issue.

Then it's gear ratio, a good racing converter, hooking it all up to the pavement.

10 flat? I don't think so. In the 10's, I don't know.

thats what im asking , what parts are needed

head porting is done by frank racing i think

cams i dont find many , does anyone make customgrinds for the 6.1?

gear , converter is decided by the cam

i dont think so either , im in the search for high.mid 10s

I think it would have to have some very high gearing to be close.

Lots of custom cams can be made for ya...frank racing, power ported performance, inertia motorsports, HHP, comp cams, indy etc... Check out lxforums.com for some buildup specs or builders.

ill take a look at that , do you know where can i get the 392 crate hemi intake manifold ? it looks a lot better than xv intake:toothy10:

For a carb application Indy makes one as well. The MP carb version intake sticks way up, through the hood. The stock efi manifold's pop up on Ebay or lxforums regularly

It can be done for sure i rekon...

Heads flow pretty well out of the box.
Say you need 530 hp to do a 10 with that weight.

Standard it makes what, 425 hp?

I rekon you can find another 100 hp easy with
after market air filter,computer to tune for optimum results,
an a bigger cam, an maybe a bigger throttle body!
I just realised now you said carb, argh..
Doesnt matter,i still think it can be done!
For sure.
Dont make me start finding you the parts lol.

Remember too,that this engine will weigh less than your
conventional 318,340,360....

I have a custom grind cam. They are no big deal, you just need to know what spec's you want. As for 10's with no power adder? Not likely unless the car weighed in at about 2000 pounds.

Reportedly a few Drag Pack Challengers have hit those times with a 6.1, although they're a bit lighter than your target weight.

how do you plan on getting spark?


6.1's are kinda pricey, for the intitial $$ you could spay a almost stock LA into the 10's

Well the 392 makes what, 525 HP? That's enough to put you into the tens in a 3100 pound car with a good chassis. I don't see why that can't be done with a 6.1. The heads are easily ported to 300 cfm's of flow at .600 lift and that would support 600 HP with the rest of the appropriate package.

You need to ask around and find some people that are running those numbers and see what they are using so you can get an idea of what works and what doesn't.

I read about a guy in Mopar Enthusiast that has a GTX, dropped a 5.7 hemi, and is running 13.321 @ 102.???, all stock motor. How much does that car way, 3500 plus or minus a few? That aint bad in my book.

13.3 is a long way from 10's though... a looonnnngggg way!

I know of quite a few stock block head, cam, ported intake manifold LX running high 11's that are in the 4400 lb range so the same settup in a 3000 lb A body should get it done. The rest of the chassis will have to be up to the task but considering most of the LX's running those times are running a 3000 RPM stall and most are stock 308 gears. If you went bigger on the stall with an A body and optimized your gears then you could cam up a little and maybe run a mid 10. For instance,,, alot of the LX's in the 11's are running a 218/222 duration on a 112 LSA on a stock block you have to limit your cam advance to about 114 ICL for enough valve to piston so you don't want to go any bigger on the intake duration because you loose too much bottom end. But with a lighter car and a high stall like 4K or more converter you could run something like a 226/230 duration and just retard the cam enough to clear the intake valve with the piston which should be about 118 ICL. This cam would be a dog in a 4400 lb LX with a 3K stall but would likley work well in a 3K pound car with a 4K+ converter. Saying the LX's with the 218/222 duration cam, heads and ported intake average 450-460 RWHP thru a full exhaust with cats the bigger cam would likley make 480 with everything being equal then you can pickup some more without cats or even more with an open exhaust. I say 10.5 is easily within reach. It would just have to be done right.

Guys, sorry but the answer is real simple....yes, easilly.

10 second time slips in an a body powered by a 6.1? Why not? 3300 pound 318 cars run in the 10's!

there are a few people that have a 6.1L in their charger,magnum, or 300c that are running a setup with no nitrous, turbo/super charger that are in 10 second range. keep in mind those cars are 4000Lbs but i dont know if they are stroked. check out the LX forums

So your telling me your 318 is going that fast,non stroked,
naturally aspirated?

Big gears,must turn some crazy rpm....

Not my car. Bob Mazzolini's.
Bob's shop is located in Riverside California. He has been building and racing Mopars for a long time.

and yes, that engine is an NHRA legal Super Stock GT/HA Class 318 w/360 heads and low comp! He has to run stock bore and stroke and factory comp, heads and carb...that's the nutshell of the rules. Many factory parts and many aftermarket additions (crank,rods,pisons,valves,intake,ported 360heads,headers)

That car is basically a pro stock car. the 6.1 will make more power so you won't require the extreme chassis to run the number.

I'm pretty confident that a stock block 6.1 in a car that was a daily or weekend driver could get in the 10's in an A body. I mean, heck theres a stock block 5.7 quad cab 05 Ram that runs 12.7x on motor at 5000 lbs race weight and thats his daily driver just bolt on the DR's and go run mid 12's with the quad cab.

this thread has me thinking real hard, those 6.1heads flow like crazy and the blocks seams very beafy in the right places compared to an old LA motor

check out the April Mopar Actions article on just that. This guy got a 10.62 @131. He runs a belle S/C @20 psi on a bone stock 6.1. It's good for 776 RWHP. He then tried to bump it to 22 psi and made 800, but blew the bottom end out of it.

Adam knew it would not last long at that high of output, but with what he had planned, he decided to see what he could get out of a stock block before it blows. He is a regular over on LXF.

Either way that is pretty impressive for the motor to make that kind of power on the short block OEM pieces.

so with a 10.62 in a 4000 lb car I'm sure one could get into the high 9's minus a 1000 lbs

Lol, I sent Adam a cam the other day. His new settup 418 will be quite a bit faster.

It is far from stock, but Hot Rod has an article on a 6.1 with over 1000 HP in their May 2010 issue. It was 510 HP and the addition of a 3.6L Kenne Bell supercharger with 24 psi of boost almost doubled it to 1019 HP.

I could be wrong but I think thats Adam with ST's car. If so he is running one of my cams in it.

It's all about the power to weight ratio.

For great mopar combinations that are proven, just look up mopar high performance tips.
These combinations are in the older parts books and can be tracked down.
They give everything all the way to the tire size for every motor.
They even give whats needed to run a 318 all the way into the nines.
They have all this info for each and every motor.
The new hemi is the latest motor so it's all new info.
They might even have a new parts book with it in it.

Maybe I'm reading it wrong, but on the Inertia Motorsports website it reports ~450 RWHP on one of their cams (SRT Max I believe) with stock heads on a 6.1... That just seems excessive to me (100+ HP gain on a cam alone). I could understand if it was crank HP, but if it's true using a 1/4 mile ET calculator with a 3000 lbs car and 450 RWHP it's dipping just into the 10's (something like 10.9). A good suspension setup will no doubt make things easier / possible.

a 3000 pound car with 450 at the wheels would need a flawless run the perfect gears and tires to break into the 10's

Those numbers are straight from past dyno sessions for a cam & a dyno Diablo tuned LX on a cool day. These new Hemi's are pretty conservatively tuned and cammed from the factory.

I agree that it would be a perfect run on a perfect day for that to hit the 10's.

if you go above 6psi on any stock internals 3rd Gen Hemi you are asking for a blown motor. replacing the internals opens the door for 20 psi boost making power

I've read of many running more than ten pounds without incident. It seems the tune is the issue, not the stock parts.

wow 10 pounds is crazy. maybe i was remembering the 5.7L

There`s a 2009 Challenger 6.1 here in Va.Beach that has twin turbos and runs 10.teens. I believe the owner is a member of the Tidewater Mopar Club. The car weighs in just under 4000 lbs. and appears as any other 2009 Challenger.

I've read of many running more than ten pounds without incident. It seems the tune is the issue, not the stock parts.

the kenne bell and procharger kits come with 8lbs pulley and they run without problems i think

im not saying that they wont run at 8lbs or more but the internals arent meant to hold up to much more than 6lbs for long!

8 lbs on a stock srt is about as far as I'd go if you want it to run over 50K miles. you can run more for a while but it will fatigue. I'm not sure 8 lbs on a stock engine will get 50 K if you push it alot. Correct though the tune is critical.

The 450 RWHP cam only dyno on the site was my web developer getting enthuastic. That guy did get a 450 dyon but then again I had a guy get 509 with that cam, ported heads and an intake and although he holds the stock block challenger record I'm about sure your typical dyno jet would put him at 460-470 and the cam only at 410-425 RWHP.
