Well I finally figured out how to get my Japanese camcorder to be friends with my American computer. So just for fun I'm posting these video clips of my Lazer Hyd. Roller cam (228/235 dur. .530lift 106 LSA) with Flowmaster 1 chamber Race mufflers. Sorry guys, its in a 69 Camaro (almost 2nd gen though:bowtie: )
And yes, I expect to get criticized all to hell for my exhaust set up.:screwup:
Outside walkaround, 42 sec.

Awesome looking car Shawn, sounds pretty mean too!!

Thank ya! I love 106 LSA. Its a little obnoxious/hillbilly for a few guys I know.. but they are also the kind of guys that ONLY like muscle cars that are F A C T O R Y original looking and sounding. Red pinstripe tires, factory window washer decals and all... very cool, but just a little boring for me.
Hey, to each his own, I guess.

Sounds awesome!!!! What do the neighbors think? Fire it up tonight @ 11:30PM, tach it to 6K a couple of times and report back to us tomorrow.:cool:

Man is that choppy. Sounds good though.

That sounds great, I miss my 106 compared to my 110

Yea, I didn't think it would be that choppy with just 228/235. So it must be the 106 contributing to most of that. But thats exactly what I wanted. 2000-6000 range too. When I go to a 383 I want to buy a cam that sounds exactly like this one, because i suppose the 383 will tame this one down a bit. By the way, all of my inspriration goes out to the video of MWilson's primer gray Camaro idling in his driveway. :) :) :) :bowtie:

One strange thing though... Lazer cams website doesn't work anymore and they're not returning any of e-mails. Uh-oh! Are they done? I guess I could always call...

About the neighbors, what a great neighborhood. One night when I was down in my basement, I heard this faint continuous sound. 30-40 minutes later, I went outside to put the garbage can out and found out that the horn was blasting on the Isuzu that was parked on the street in that first video. It was winter time and I guess something with the freezing cold had the horn switch stuck on. How annoying for neighbors. No one has ever mentioned it.

Sounds great man! Sounds like my car when its in gear.


This video is at idle at 1,500rpm. Mine has 105 LSA and alot more duration than yours. Its running through 2 7/8 hooker super comps and 4" dynomax bullet mufflers.

sounds great man it is amazing its that choppy at that duration looks like you got a good sound and great low usable power band, I was expecting you to get on it a little though when you were driving! Car looks great.

Maybe I'll update a video with some throttle fun.

About the choppy idle. I'm amazed too. Thats why I'm a little concerned that if I go to another cam company in the future, I won't get the same rumpity-rump. I would really like to hear another cam companys cam of similar specs in a 350and see how it compares.

Anyone help with that?

well what stall do you have? What compression will the 383 have? the cam in my car is rated for 10.5:1 I have more than that but ran it because I liked the DCR, you may be able to go with more in the 383

This one seem's to be working!

The founder of Lazer Cams, Bill Metzger, died last December. For a while the future of Lazer wasn't clear, but recently I think Bullet Cams bought them out.

Shawntmartin sounds very nice also nice 69Camaro also,Sounds clips are great.

sounds wicked!

pdq67,

Yea but the main page doesn't work.. that has all of the other info. And hasn't for awhile. Crap. Theres go getting another cam from him.

MWilson, I have 10:1 and a 2200 stall now. The 383 will get 10.5/11:1. Damn, I wish Lazer was still at it. If they were bought by Bullet then I'm sure things will change.

Shawn -- sounds like your idle speed is a bit low, what RPM is it idling at?

Nice car, btw. :cool:

I thought it was the begining of the VH song, Hot For Teacher. :cool:

I have 10:1 and a 2200 stall now.

That converter is a little on the tight side for that cam. Something in the 2500-3000 stall range (for street/strip use) would put a lot bigger smile on your face when you floor it from a dead stop.

Yes it was still a little cold... 600-650RPM. Did you think it was still low in the second video? Theres only a few seconds to notice it before i pull off.

:D :D :D

Yes it would;) The power range is 2000-6100. So it barely does the job. but It will burn the tires from a stop now... no traction with these BFGoodrich's

Crackle Crackle! Sounds good. An off the shelf 3000 stall like a B&M Holeshot will do you some good.

Sounds like a good Christmas gift;) I plan doing a few things this winter, tie the frame, maybe disc brakes (maybe not?), fix the leak where the drive shaft enters the pumpkin, and a stall install. So yea, Santa might have to bring a stall.

Even cold that is way too low dude. The engine sounds like it is barely running. I would crank in more idle speed, up around 900 or so. I run a 259° solid FT cam on a 106° LSA and it runs at 1200 RPM idle, hot. Also, did you set your idle mixture screws with a vacuum gauge? If it is too lean at idle it will sound choppy as well. The car sounds great driving down the road, I'd just up your idle speed a bit.

Sorry for the hijack but does anyone have a video of a 108 LSA

mine is 262 @ 50 and idles at 850-900

Dirt Reynolds,
Unlike newer cars that run at high idle until it warms up and kicks down...my engine idles low until warmed up. Then the idle goes up tp about 750-800. Thats why i asked you if it seemed better in the second video where my temp was 190 and it was idleing at 800. I can up it to 900... thats where it was a week ago before i lowered it, I just thought 900 was too high. thats what salleechevrolet.com told me anyway. No biggie....

These sound video's are way COOL!!!:D

I would work on fixing your choke. You should always have higher RPM upon cold start to bring the engine up to temp as quickly as possible. Your carb setup there is bass-ackwards, imo. I don't have a choke on mine -- I removed the choke horn off my 830 annular -- and what I do is turn on the electric fuel pump, give the carb 4 or 5 good pumps and turn the key. It fires right up and I idle it at around 1800-2000 RPM until it warms up, which in a 408 with a street fill of Hard Blok only takes a few minutes. The idle settles in at around 1200 or so. In my case I have relatively high open spring pressures and idling too low an RPM with my oil pan having a diamond stripper windage tray, crank scraper and lowered sump can all limit the amount of oil splash a solid FT cam lobe recieves. Some guys run low idle speed with cams like mine then wonder why they wipe a lobe out from street driving it after a few months. When Doug (Rustbucket79) and I were talking cams back and forth one day, he recommended around a 1200 RPM idle with this cam, since he had ran it also in his last 408. In your case you have a hyd roller but I like to run with a bit more idle speed with a big cam, which gives me better throttle response off-idle. As usual, just my one man's opinion. :cool:

Dirt.. You make a real good point about the idle speed and oiling. I noticed that on my car a couple of years ago.

I set idle speed to 600 RPM..My digital oil pressure gauge showed 9 psi oil pressure. I brought idle up to 800 and oil pressure went up to 17 psi.

My oil pressure is lower than most but thats cause of the way I built the engine. I ran loose bearing clearances right close to the max all the books says is the most you want to see on clearances ever.

I just thought of something aiding my cars low Idle my timing is locked out at 37, my oil pressure drops to about 15-20 at idle hot

My idle is low when cold....due to the choke being wired open? You think if I unwire it it will close and raise RPMs? If not, why in the heck is my engine low when cold and yours is higher when cold. Do I need to remove the choke completely? Its a Edelbrock 600 manual choke. im gonna make this a new post since this threads subject has changed and more people can answer, as well....

You need to unwire your choke and put a choke cable/pull kit on your carb. You can buy the cable for under $10.

It mounts inside your car, under the dash.. Runs through firewall, then hooks up to the choke on carb..

Now you can control the choke plate. On 1st start up's close the choke.. Crank engine, as soon as it cranks open choke just a tad.. Now it will run faster as it warms up, then once warm you open the choke all the way

Mine is higher when cold because I use my right foot to keep the RPM's high. If your choke is wired open, like Nightrider mentioned, put a manual choke on it at least. The wear and tear on your engine at cold idle like that is not good. You need to bring cold RPM's up to a decent speed and maintain it. That is why the OEM's put chokes on their carburetors.

Oh hell.... I didn't know that you are using your foot. Thats what I'm doing too... my only mistake is that i was in a hurry to leave for a car show, and I went and got the camera to record the idle beofre it was fully warm. I thought you had some car that was acting like it had a choke without a choke... and I wanted to know the secret.:confused:

No secret -- except I do not let the engine run lower than 1800 RPM until I see the temp gauge at around 150-160° or so. At that point I let off, let the idle speed come down to 1200, and at about 165°-170° my electric fans come on automatically and I'm good to go. Ths usually takes 3-5 minutes -- 400's warm up fast.

Listening to your car idle reminding me of the opening drumwork by Alex Van Halen in "Hot for teacher"...lol!

Seriously,I would not let a roller-cammed motor idle that low.Dirt is right,1,000 rpm's would be an absolute minimum idle for your motor.My 383 stroker in my '69 has a Comp Cams solid roller w/110 LSA w/.576" intake lift & .582" exhaust lift (duration 248@.050" intake/254@.050" exhaust) and my Pro-Systems 830cfm carb has no choke or choke horn so I foot-idle it between 1500-2000rpm at start-up for about 4-5 minutes before I drive off.Even at stoplights,I keep the revs up to 1200-1500 rpms or so.
