My friend owns a performance shop and he works mostly on vettes. I asked him to spec out a cam that will produce good power along the other mods he's doing, but still drive like stock. This is what he came up with. I was hoping for a lower LSA so it will sound very lobey at idle, but he said they can tune it to sound lobier. Anyways, what do you think?

Small world, I'm in League City too. What shop?

510 Race Engineering. They recently moved to Katy.

I am running a 231 247 lsr cam with about the same lift and a 115 lsa. it lopes quite good. it gives the car a good shake. it puts down right at 550 hp and 500 tq. drives very good but will slightly surge under 1600 rpms in lower gears but can cruise in 6th at 1100 rpms all day long with no surge.

Here's where your cam is from an overlap perspective.

overlap = ((intake+exhaust)/2)-(lsa*2)

OEM LS7
211 / 230 @ .050, .591 / .591 lift, 121 LSA
Overlap = -19.5

Katech Torquer 116
220 / 244 @ .050, .615 / .648 lift, 116 LSA
Overlap = 0

Lingenfelter GT19
227 / 239 @ .050, .678 / .688 lift, 114 LSA
Overlap = 5

RagingRacing Stalker
224/246 115
Overlap = 5

Lingenfelter GT17
228 / 232 @ .050, .621 / .630 lift, 112 LSA
Overlap = 6

Your Cam
231/246 .653”/.652” 115LSA
Overlap = 8

Katech Torquer 110
220 / 244 @ .050, .615 / .648 lift, 110 LSA +004
Overlap = 12

RagingRacing Lethal
232/250 113
Overlap = 15

Lingenfelter GT21
243 / 259 @ .050, .663 / .702, 112 LSA
Overlap = 27

RagingRacing Punisher
236/256 111
Overlap = 24

RagingRacing Striker
244/256 110
Overlap = 30

This should work fine and drive nice.

Not to sound like an idiot, but how does overlap effect my driveability and idle? I only know the basics when it comes to cams.

SlayerRX8

Overlap is the biggest factor in determining the drivability of a cam.

As you can see in the list of cams, the one you selected is relatively mild. Everyone has a different opinion on what is a PITA and what isn't, but I imagine most people would find that cam to be very livable.

2000FRCZ19

more overlap means more surge and less drivability. it makes the idle choppier but the cam you have selected will be choppy and can be tuned to be even choppier if that is what you like. here is mine at a 9 overlap and with a 115 lsa.

slash8915

Wow, that actually sounds pretty dang good. How's the driveability?

VicCaerter

sounds nice. enough to let know there is something going on, but not over the top.

2000FRCZ19

its really good. not exactly stock but very dd friendly. i drive it in stop and go traffic very often. (beach traffic and stop light to stop light) i also take it on extended trips. it does it all very well. it has power all over. nice low end tq with a good hit at 3500 that pulls harder as it climbs. its a good dd cam that makes great power and doesnt take away from drivability.

You really need to take a serious look at the Phantom cam from Lethal Racing. It's nice and lopey without being annoying (gentle movements idling, not wild shaking like my Lethal cam was), yet drives damn near like stock. I love this cam and it has good power/torque. Click the link in my sig for dyno sheet and video.

Mookster

Since i cant see ur sig...can u post video and the power it makes? Also, the specs of the cam if u know them?

Thx

Has any information been provided on these cams that if installed and tuned, that the car will pass emissions sniff testing?

93Polo

How much advance does the LPE GT-19 or Raging Racing Lethal have?

VetteVinnie

Not likely. If you need to pass a sniffer test, stick with forced induction.

DaOtherOne

I don't know.
