Default Cam specs odd! Need some input.

I've been looking at this cam for a while now sitting in my shop so it tore my motor down to put it in and now I'm second guessing it because it seems like an odd cam. Its 232/236 542/545 112. Has anybody ran anything even similar to this in an LS1?

the lift seems a little low for that duration.... but maybe its a custom grind cam for somebody with 1.8 rockers?

otherwise... the rest of the specs seem pretty normal

Its a comp lobe. It was actually bought for stock LS1. I thought about the 1.8 rocker deal too but that wasn't it because I got the whole motor from a friend and it was stock except for the cam. It just seems like the duration doesn't match the low lift.

Looks very similar to Comp Cam Xtreme RPM lobes #3756(232 @.05", lift .541"), and #3757(236@.05", lift .544").

Similar to the famous Tigershark cam by the one and only Ed Curtis. Not sure what the intake/exhaust lift number are, but pretty sure it's ground on a 113 LSA, although I'm sure there are variations. Nothing odd about those cam specs at all.

Sounds like an older "big" grind to me. Probably work great in a stock head car.

There are a ton of people running this cam on the GTO Forum. Like I said, it's an Ed Curtis cam called the Tigershark. I don't know what the hell you think is odd about it. It's a pretty common 4 degree split cam, with an intake and exhaust lift that works well for stock heads, with an LSA that pretty much every other off the shelf LS1 cam has, or at least is offered in. It's not like it's a 211/243 106 LSA cam with .455 and .455 lift. Now that's odd.

Run that cam, it will be torquey as **** with lots of mid range and top end. Perfect for an F-body looking for a good DD car that will post good drag times, too. With the low lift, you can run beehives, with the added benefit of good high-rpm stability-- you can run a higher shift point.

Its not like its a unicorn or something, but I don't know anybody who has a cam that's much less than .580 lift with an .050 that high. The split is normal. I bet if I asked the same question about a cam that's 232/236 614/620 I would have a million people on here giving feedback because that's more common with that duration.

Why are you worried about the lift? Do you have some super bad-*** heads that flow a **** ton of air that would benefit from a cam with that high of lift? The lift that cam has will shine with stock 241 or 243/799 heads.

No bad *** heads, Just a set of ported 799's which isn't the issue. Its not the lift I'm worried about. Its the combination. If the duration was 216/220 I would never have thought twice about it.

because Lift can add virtual Duration without actual duration changes...

if the Head stalls out at .600, then most uninformed people will order a cam with lower lift and go for a duration they feel suits their needs...

but if you dont mind a more aggressive lobe profile, you can get a duration over the nose that is longer (which creates more power)with the sacrifice of spring life

the best of both worlds is to get a medium to mild profile with a longer duration and a high lift
if the head stalls out at .600 and you lift past that...you basically just created a longer time over the nose of the cam...without the grief of an extreme ramp rate to get there.

classes that have limits on what heads you can run take advantage of this and run huge lift cams to overcome the shortcomings of the head design because its not about peak lift, its about total air flow into the cylinder.

I just looked at that tiger shark cam. Its like .600 lift! Its nothing at all like my cam. That is a perfect example of what I would expect with 232/236. Geeez.....

You say you have the cam in already, so how does it run? What kind of numbers did it put down, or what kind of ET's did it run. As long as it runs good and you are happy with it, then I wouldn't worry too much about it.
