HP increase with new cam?

I'm having a new cam put in my otherwise stock 1998 LS1 in my Corvette. I am just curious how much if any HP increase I can expect. Here's the cam spec's:

COMP Cams Xtreme RPM Camshafts
Cam Style: Hydraulic roller tappet
Basic Operating RPM Range: 800-5,800
Intake Duration at 050 inch Lift: 206
Exhaust Duration at 050 inch Lift: 212
Duration at 050 inch Lift: 206 int./212 exh.
Advertised Intake Duration: 259
Advertised Exhaust Duration: 265
Advertised Duration: 259 int./265 exh.
Intake Valve Lift with Factory Rocker Arm Ratio: 0.515 in.
Exhaust Valve Lift with Factory Rocker Arm Ratio: 0.522 in.
Valve Lift with Factory Rocker Arm Ratio: 0.515 int./0.522 exh.
Lobe Separation (degrees): 112

Thanks!!

You say otherwise stock, so does that mean stock exhaust as well?

10HP

That cam is barely bigger than stock. That's a lot of work to swap out a cam for 10HP.

talk about baby cam.

Not everyone wants nor needs the biggest donkey dick cam you can fit in a stock block but that thing isn't even worth going through the expense of installing...

I reckon it will be very torquey compared to the gutless low down tq of the stockie. I can't wait to see your results as I'm awaiting my little baby cam which is only a tad bigger.

You should notice some nice hp/trq gains down low, but I wouldn't expect any above 5k, especially with a IVC of 33. It's going to peak 200-300rpm lower than the stock cam, so if you want the new cam HP to peak around the same rpm than the stock cam I'd retard the cam 4* from the 2* advance it had ground in to it, that would move your IVC to 37, and the ICL to 114(up from 110 ICL). Now if you don't have the cam yet Id go with a 212/218 with a 113lsa up to 115 lsa

OK. Point taken. Is this a better performer?

Engine is completely stock: exhaust, intake, etc.

How will this cam work:
Basic Operating RPM range: 1,500-6,800
Intake Duration at 050 inch Lift: 226
Exhaust Duration at 050 inch Lift: 226
Duration at 050 inch Lift: 226 int./226 exh.
Advertised Intake Duration: 275
Advertised Exhaust Duration: 275
Advertised Duration: 275 int./275 exh.
Intake Valve Lift with Factory Rocker Arm Ratio: 0.598 in.
Exhaust Valve Lift with Factory Rocker Arm Ratio: 0.598 in.
Valve Lift with Factory Rocker Arm Ratio: 0.598 int./0.598 exh.
Lobe Separation (degrees): 111

Thanks for your patience and your input.

Since it's bone stock, you need to look at exhaust as well as a lid. Plus you probably need to look at a cam kit that includes everything you would need. Something like this:

http://vengeanceracing.net/index.php...-kit-plus.html

The VRX2 (224/228) or VRX4 (228/230) would be good with stock gears in an M6. If you have an Auto and don't want a higher stall torque converter for some reason, the VRX1 (220/220) is good. One thing I like about the Vengeance kit is it includes everything you should be prepared to do with a cam install (pushrods, BTR Valve springs, Melling oil pump, C5R timing chain, and Comp Trunion upgrade for stock rockers + gaskets).

Tick also has a good cam kit with most everything in the above sans the Trunion upgrade, but I would get that as well. Martin@Tick has some well thought out cams as well. I'd do the TorqueMax Stage 1 (223/227) or Stage 2 (227/234). Here is the link:

http://www.tickperformance.com/tick-...1-ls6-engines/

And if you'd rather piece together your own kit based off the information in the above two links, I'm partial to EPS cams, because of their endurance lobe profiles for performance and reliability as well as the use of a billet cam core (which is why the cam costs more). Here is a good one for you that's 222/226:

Second cam is at least worth the time and money of the install

i sure hope your upgrading valve springs if they are not already upgraded. ls1 weak spot! that first cam is too small. my ls6 cam is too small and im really conservative.
