zaathur151 Posted March 5, 2014 Report Share Posted March 5, 2014 (edited) hello noobie here mainly browse fullsizechevy but firgued this is the place to be for lq9 motor swap questions Im about to order a used lq9 out of a 07 classic to put in my 2000 1500 4wd my biggest concern is what cam, I never bought one before but have installed one for a friend only I have did some searching but still unsure here are my specs will be 07 classic stock lq9 im planning on using my intake and injectors off my 2000 5.3l, current mods are build tranny/ k&n COI / shorty headers/ with/ magnaflow ypipe/ and there coverters with a/ Flowmaster 50/ series turn down I have stock converter but can change to a stall if needed. I plan to have no more future mods than that, I will have a tune done also after the swap I daily drive this about 10miles a day so would like desent road manners hardly ever tow just want good low end torque but want to here a cam lope at idle thanks any ideas will be appreciated Edited March 5, 2014 by zaathur151 (see edit history) Quote Link to comment Share on other sites More sharing options...
12'SROCK Posted March 5, 2014 Report Share Posted March 5, 2014 Good low end tq and a high stall converter don't go hand in hand. You will blow by your "low end tq" with a performance converter. Quote Link to comment Share on other sites More sharing options...
BLOWN SS/T Posted March 5, 2014 Report Share Posted March 5, 2014 What are your goals? If your worried about street manners then what's wrong with the stock cam? Not saying a custom grind won't have good street manners. And why are you chasing torque power? The gains from the lq9 over your current 4.8 or 5.3 would be a significant difference. Idk if that will be enough for you or if your still looking for more, or is it the cam lope our chasing? I think with a 224/224 cam you'll be happy and maybe even a circle d 278mm 3000 stall. And you could still tow with that converter. But definitely think about what you need from the setup and how your gonna be using it, and I think that'll help people guide you in the right direction.

JC03SS Posted March 5, 2014 Report Share Posted March 5, 2014 Like said above there are tons of cam's. You need to come up with a game plan and go from there. A camed SS is fun to drive for sure. Gl Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted March 5, 2014 Report Share Posted March 5, 2014 What I would first due is consider if gas mileage is a concern. How often will it be driven and if you want it to have street manners. Any decent cam will give the cam sound. Buying a cam just for the sound isnt going to help you any. There are alot of variables that go along with a cam. HP gains and torque curves. Where you want those gains as far as low end RPM, high end, or throughout? gas mileage how deep you want to go with it? Rocker arms? Springs, retainers etc..... Manners on drive ability? Will this cam be enough for you long term? you shouldnt have to do it again and again.. All motor cam? N20? blown? I can go on and on. Your best bet is to answer these to do the job once. Then talk to a engine builder to make sure you are getting the best choice. Im not saying people here dont know about cams and cant help. But whos better to talk to than someone who has first hand experience as a builder to finalize your decision?? As for converters, thats a whole other demon. That will also reduce gas mileage. Cost all depends on the quality and how high of a stall speed you want. How tight or loose you want the converter, what size diameter it should be etc.... Most go with the TBSS converters with a smaller cam as it works well, and doesnt cost a arm and a leg. Do a search, there are tons and tons of these threads, it will help answer your questions.

This is my daily driver I drive mostly city driving so my speeds are a max off 45mph with maybe a weekend drive at 70mpg for 35 miles or so I would say throughout rpm range would be nice as far as gas mileage I would like to average 13mpg at least would hate to have 10mpg half ton truck and valve springs would be as far as I would like to go, as for road manners would like to find a good medium and this motor will remain stock exept shorty headers and exhaust/CAI/cam/e-fans/built tranny and a good tune I plan to do no more modifications and for a converter its only if people recommend it would be best for my drive style amd cam choice, I want a cam mainly for sound and the motor is out would be easy to put in while out and just some over all power gains, also this truck has a front leveling kit with 33" tires with stock gears of 3:73 Edited March 5, 2014 by zaathur151 (see edit history) Quote Link to comment Share on other sites More sharing options...
rickyrick562 Posted March 5, 2014 Report Share Posted March 5, 2014 Whats wrong with 10mpg lol jk. Good luck with your build Quote Link to comment Share on other sites More sharing options...
GI.SS Posted March 6, 2014 Report Share Posted March 6, 2014 I think something under 220 with a 3000 stall is what your after. Also sell those shortys and pick up some long tubes. The shortys have zero performance gain. Look into some corvette servos they're $20 and easy to put in. It will give you some nice firm shifts while your at it Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted March 6, 2014 Report Share Posted March 6, 2014 The shorties do have performance gains. More torque and power down low. Long rubes gives you more HP and less torque higher in the RPM's. HP doesnt get you going, its torque. Quote Link to comment Share on other sites More sharing options...

Aldofashow Posted March 6, 2014 Report Share Posted March 6, 2014 (edited) I have a yank ss3200 and works fine I wouldn't go bigger as it could be to much for a daily driver from what you described 3000-3200 would be perfect make sure you go with a good company yank or circle d seems to be one alot of guys here like and there are a couple more others here have used that could refer A good converter will move the truck under the set stall rpm until the right pedal gos down mine is 3200 but I cruze down the road at 1500rpm Edited March 6, 2014 by Aldofashow (see edit history) Quote Link to comment Share on other sites More sharing options...

onebadmax Posted March 6, 2014 Report Share Posted March 6, 2014 (edited) Not really but I am wondering where they are. I haven't seen them heckle anybody lately. Just trolling for some activity, carry on. Edited March 6, 2014 by onebadmax (see edit history) Quote Link to comment Share on other sites More sharing options...
JC03SS Posted March 6, 2014 Report Share Posted March 6, 2014 I can say one thing those 2 do know a lot about these trucks. Brian has helped me before. I'm still learning so I try and keep my ears open. Quote Link to comment Share on other sites More sharing options...
