I'm assuming you have NPP in a box to control the mufflers. If so, the controller is in your right hand cubby just inside the trunk. Take the controller out of the system by hooking the vacuum feed...

I can tell you that NPP's closed fall 20hp short of NPP's open. That's on a 470rwhp cam and bolt on LS3. Saw that on a dyno. NPP's open get you an extra 6 hp vs stock narrow body mufflers on a stock...

Well, shoot. If your current oil cooler is mounted like a ZR1, ZR1 headers should fit just fine. Just get the correct mid pipe to connect to your current axle back mufflers.

Get you a Dewitts radiator with the integral EOC. You have to remove the radiator to change the cam anyway. All you need to make it a bolt in affair is a couple of GM hoses for a Z51 Vette. These...

Shoot, got too hot today. My total overlap calc was off. Your cam having more overlap wasn't. More like an extra 2.5 degrees of overlap. The OP's cam at 5 vs your cam at 7.5. It won't drive the same....

Be mindful that some folks aren't after the last HP Another 3 degrees duration on the exhaust side, while possibly can get you a few more HP, also gets you another 1.5 degrees of overlap. Some,...

Find you some LS3/LS7 injectors. I think your stock LS2's will be done before you reach 500. LS2's are 33#ers vs 42 for the LS3/7 versions. They're inexpensive and show up quite often in the C6...

I think I grabbed the part that was unglued with a pair of pliers and pulled to get the paper part off. That left a lot of the adhesive still on the intake. I just rubbed the adhesive one way and...

If you are going to mod the engine, start with an LS3. You don't need a CAI as the stock one will do. You don't need an aftermarket intake manifold as the stock one is very good. Stock LS3 heads are...

The LS3 in a Camaro and the LS3 in a Vette have different accessory spacing. A kit designed for a Camaro WILL NOT work on a Vette. Plain and simple.

That one had 60# Motrons. It had a little room. Maybe 80% duty cycle if memory serves. Pulley down to a 3.25 and you have all of the easy Hp available with a TVS2300. Sure, you can get more, but to...

Get you a 224/230 115+3 with lift around .600 lift on both sides. It will have a little chop to satisfy your sound needs. Shouldn't be too hard to tune for near perfect manners. Add BTR Platinum...

Sammy is spot on with the HP estimate. With the belt you have now, if you can easily get it on and off....it's too long. The more load you put on the belt, the more it's going to stretch. And the...

If your OEM filter provides all the air your engine needs without restriction (and it does), a bigger, badder, freer flowing, carbon fiber, whatever..... isn't going to make more power. You can't get...

I believe the fly cutting comes in when you mill the heads to maintain the LS2's 10.9:1 SCR. LS3 heads have bigger combustion chambers vs the LS2 heads. Kind of defeats the purpose if you do an LS3...

I don't think you're going to see 1000 rwhp with a TVS2300 even with lots of nitrous. I needed 5th gear with a base C6, 4.10 gears and only 640 rwhp. Yes, 4.10's will definitely accelerate...
