Need ppls input on some upgrades!!
I want to upgrade a few things and have quality parts but also don't wanna go broke. I will be redoing my whole exhaust, going with ARH LT's but with a true dual setup and I want the GMMG chamber exhaust. (Thoughts on that setup?) then I want to do a head and cam setup as well but I'm not that well known in that dept. so I've heard many cams in the camaro's and I think an LSA cam or comp cam is what I might go with but don't know which one. I definitely want it to sound aggressive but don't want it to die when it's idling. And I have no idea on the heads. I also want to do a timing chain, and UD pulley. So need input on both of those. I also want to do different injectors as well. All in all do u guys believe those upgrades would be good and which ones should I go with without going broke but also spending a good amount for a good brand? Any input would be appreciated. Car is a DD so I'm not looking to do track time, just want the power. Looking to be around the low 420's hopefully. Car is already loud and obnoxious, and I love it!! But of course I want it louder.
I would definitely do a head/cam combo.
For the heads: I would try to pick up a pair of 243 heads from craigslist and you can do some MILD home porting (more polishing than anything) on them. They flow well and I believe are great "budget" heads.
For the cam: I would go with something around 228 and valve lift of .560-.580. There is A LOT more to specifying cams than the numbers but I'm speaking in generalizations. I wouldn't go with a monster cam for your application, as a more "mild" cam is easier on the whole assembly and still has good manners after a tune. For off the shelf cam, I would go with something like this: www.lunatipower.com/Product.aspx?id=2024&gid=288. (www.youtube.com/watch?v=03c4Pl5s-Yc) Most people will suggest to spend a little more money and get a custom ground cam from Pat G or someone similar. That's your call. I would also look at upgrading the valve springs.
Timing chain: LS2 timing chain. Texas speed sells them. Heck, Summit has them for like $30. A lot beefier than stock.
Injectors: I would get a tune and see what their duty cycle is before upgrading.
If it is your daily driver, I would leave the pulley as is, but people have differing opinions on this.
I'm sure others will chime in with what they think, but all of what I said is just my opinion. YMMV

Also remember, miscellaneous fluids and gaskets add up fast, so look into that while planning your build.

Oh and don't forget tuning as well

IMO, save your money and leave the stock heads on. You can get a decent cam with great street manners and be around 400ish rwhp. If you want that extra power, that money you saved on heads, can go towards a nice nitrous setup. Then you'll be around a good 500rwhp

p.s. thanks for your service!
p.s. thanks for your service!Yes you will still need to change the springs if you do a cam. I would call your preferred sponsor and tell them what you want in the car/what your goals are and they will recommend you a camshaft and the parts to go along with it.

I really like the IWIS timing chain, and I use it a lot. It is made by the same company that makes the Katech C5R chain, and it is a high quality product. For the UD pulley, I honestly am not that big on them. If you do want a good harmonic balancer though, I'd highly recommend a ATI unit.
For larger injectors that won't break the bank, I use the Fast 36 lb/hr units a lot and they are only 300.00 dollars and work very well.
I'd also suggest a trunion upgrade, Melling high pressure oil pump and you'll also need head gaskets, timing cover gasket, timing cover seal, water pump gaskets, head bolts, balancer bolt and cam bolts.
If you have decided that you don't want to do the heads, yes you'll still need to install a dual spring kit on the stock heads and you'll also need stronger chromoly push rods as well to go with the cam swap.
I may of missed it, but is this a 6 speed or an automatic?
I would love to help you with your build, and I can supply all the parts listed above along with others that have been mentioned. So if you have any other questions feel free to ask!
