Cam only LT1's run11's??

**Beagle** · 10-07-2009, 05:33 PM

my car touched high 11's on a 125 shot with longtubes 3 inch exhaust all the way back, cold air intake, drag radials 3600 stall and a tune. No way an lt1 cam only will touch 11's with the same mods minus the nitrous.

Did you have a cam? What were you trapping? Go poke your head around on camaroz28.com. They are/were the biggest site for lt1 cars. I think the cam only record is 11.1@117 with a 3200 lb race weight.

look towards the bottom of the list, there aren't many cars on the list for some reason but there are plenty in the 11's, especially on some of the custom ground cams. Mine was right off the shelf.

Yea ive been on that site for years. 11.1 no f ing way cam only. Theres more than just a cam in that thing probably some more cubes. No 100 percent stock motor with just a cam will run that. Impossible. 11.1 hahahahahaha

Well, that was on a 1.49 60' time. Thats .5 seconds faster than my best 60.' They say .1 on the 60' is good for .15 in ET. So that would drop about .8 off of my 12.3 bringing it down to a 11.5. He has 3 more mph than i do so thats about 30 more hp, another 3 tenths off and you get a 11.2.

Not too unrealistic to me. Bret has been grinding custom stuff for stock head applications, i can see a car picking up another 20 hp with that and aggresive tuning. That car leaves HARD. Mine was more like a bog and then haul ass the rest of the way down the track. Who knows what the DA was that day either. It can be done, you are just sour because it took you a large hit of nitrous.

To many people lying about their times out there. show me a cam that will add 100-150hp cause thats about what it will take on a stock lt1 to get close to11's. I could maybe see a high 11's like 11.999999999 but no 11.1.

***SNOOP*** · 10-08-2009, 08:50 PM

When I say cam only, I mean cam ONLY.... 3200lb race weight is not stock.
CAM ONLY!!! NEVER!!!!

BONE STOCK WITH A CAM!!!! NEVER!!!!!!

Exactly...... atleast where on the same page.

**SSLEVO** · 10-09-2009, 12:06 AM

LISTEN, cam only refers to a setup using the stock longblock, any other bolt on stuff is included in that. I don't think any one in their right mind would throw ONLY a cam into a stock engine. The exhaust would choke the motor so bad it wouldn't gain anything. Not to mention the stock springs can hardly control the factory cam.

What does a stock M6 lt1 car dyno? Maybe 230-240 whp. Add some simple bolt on stuff to let the engine breathe and a cam and i made 366whp. That's 120-130 more hp than stock. You guys can go on all day if you wish, i've been there before.

**Yooformula** · 10-09-2009, 12:33 AM

sorry but I am having a hard time seeing how headers/catback/cam/tuning nets an LT1 120-130hp gain!

**Crawlin** · 10-09-2009, 07:31 AM

doesn't have it. proper stall setup for the car will get the e.t. itself down quite low. Like my old red car. stock 13.4, added the 3200Vig and it went 12.6's, no power adding mods at all added at the same time.

and an LT1 car at 3200lbs with driver is not stock weight. That's probably 400lbs ripped out of the car.(assuming driver is right around 200)

Well i had more than that, 1.6 rockers, 918 springs, electric water pump, 52mm throttle body, 30 lb/hr injectors, 1 3/4 LT's, hooker catback, K&N cold air intake. The "cc306" is a pretty nasty cam for stock heads. The car moved out, 114 trap speed all day long with a 3700 lb raceweight. Most bolt on only guys dyno around 300 rwhp. Another 60 hp from tunning and a big cam doesn't sound so far off.

agreed! 3200lb is NOT stock weight....my Formula(cloth int) weighed in at 3340 with an empty tank with no driver and STOCK as in a day from the dealership stock...went straight to Moroso the day after I got the car.

**Beagle** · 10-09-2009, 05:28 PM

So how come the fully ported heads and cam cars run high 11's low 12's with the supporting mods then? This thread is useless. Anybody have a cam i can borrow for my camaro. Ill prove to everyone this is not possible. My car hit a 12.9 once on motor and consistently wnet 13.0-13.3 with a 1.6-1.8 60ft. So with a cam it should be equivalent to my 125 shot that it took to barely get into the 11's. Right.............

Because they don't have their shit set up right and can't drive. My car ran 13.1's with all the bolt ons like your car but that was on a 2.0 60'. I put the cam in and ran a best of 12.3. Thats on a 1.9 60' time. Throw in some gears and its 11's easy. I didn't get that far since i sold the car. All you people have is speculation, i fucking did it, lol

**67-400** · 10-12-2009, 06:43 AM

My factory TPI set up with a mail-order performance chip was running low-12's

Take mine for example.....

1997 Z28, 285hp at crank. Figure 20% drivetrainloss = 228 hp at wheels. Add longtubes, ORY, Catback, K&N CAI, and a tune. Car put down 295.7 at WBD Dyno Days earlier this year.

Not bad for a Z28 with 99k on it

Sounds about right, most bolt on cars roll about 300. Throw a cam in and you pick up 40-60 hp. If you have a heads cam package these days there is no reason you should roll less than 400 whp. The lt1 is still a great engine, the ls1 will make 40-50 more hp with a cam or heads/cam combo so thats why the lt1 gets put on the back burrner. Hell, the new ls3 vetts are almost making 500 whp "cam only"
