well ive had my 03 1500hd lq4 for a little over 3 weeks now and so far i have leveled it, de-badged it, tranny flush,and a k&n intake. I LOVE IT!! My first gm product and i aboslutly love it. now im looking to throw some parts at it. I was thinking a mild cam (suggestions on size please!), ls7 lifters, pushrods and valve springs (still deciding on what to get), ls6 ported and shimmed oil pump from texas speed, maybe a yank 3000 stall, headers, and a magnaflow of some sort. What do yall think? I am new to the gm world and after much research i believe i have came to a legitimate parts list. It still has to be my daily driver but when a ricer pulls up i want to blow its doors off. I appreciate it very much!
ill post pictures of the truck as soon as i figure it out!

 

anyone? I was doing some research here and found that the 212 218 was a very popular cam. I am basically looking for something that will still have stock, maybe a little extra power on the bottom end but i want most of it on the mid to high end. I will probably never tow anything so that wont be a problem. I am going to get a stall later on probably a yank 3000 or 3200. and should i get push rods or can i reuse the stock ones? If i have to get new ones what are the correct size for my engine?
My truck is an 2003 gmc sierra 1500hd 2wd ccsb 3.73 limited slip and 4l80e. i might also regear and get 4.10's with an aftermarket locker.

 

As always. A custom tine is a great way to wake up your truck. Check out some sponsors lime nlackbear nelson amd wheatly and see about the tunes they offer

 

Yes tune headers, converter cam and so on list can go on forever. I just installed my 212/218 and love it

 

I would say read the parts list at the bottom of peoples posts and u will find what parts, what and how much power, how fast in a 1/4 and go from there. And don't be affraid to send people PMs to ask about their builds. U will find a lot of helpful people with a **** load of knowledge. Best of luck with your new addiction!

 

thanks! im just trying to find out what i want to do so i can start buying parts. right now im just trying to get the best fuel economy out of it right now and then ill install the parts after im done with school and start my diesel tech job.

 

Good deal. like the other guya said. look arouns and dont be afraid to ask. i would start with a tune stall and headers and go from there. those mods are big winners for.our trucks lol. have fun with ur truck

 

When you install the 212/218 what else do you have to do? I heard GM made a cam that they put in their 5.3 crate engines that is pretty good and not too radical, but I havnt been able to find it.
