Well I am swapping out my cam after only a month. I have had several recommendations but everyone seems to agree with PatrickG's cam as the best power maker with a gnarly idle. Here is his recommendation.

LSK/XE-R combination 235/242 .649/.605 110LSA +2advance

Sounds like a winner. Patrick knows his stuff, the other cams recommended were close, but this is the one. I'd like to hear everyone's opinion no matter what it is. Think its too big for a Daily driver, etc... Whataya think? I am ordering it today if no good debate with other ideas shows up.

I'm considering going with that cam myself, but since I like the low and mid-range punch, I may go with +4 advance for my application. +2 will make more peak power and carry it out further whereas +4 will be a little torquier down low due to slightly higher DCR. Can't go wrong either way.

I don't think you can get away with running stock rockers with .649" lift without tearing up the valve tips....with any head. I would like to see some valve tips that have been run with this much lift and stock rockers.

Huh? Is this just an assumption or based on experience? I only ask because I've had no personal experience with tearing up valve tips running this much lift and stock rockers and neither has Thunder Racing. They have customers that have been running LSK lobes for over a year with no reports of premature valve wear.

Haha, I come back fromthe engine builder and he said the same thing. He doesn't trust the rockers with that much lift. He also thinks we would have to flycut the pistons for sure. Is PTV clearance going to be an issue? I need to come up with a cam soon.

lift isn't the problem with PtoV clearance, its duration.

Yes, the Lift was a concern with the rockers. I am hoping to get the cam selection right on the second try. If I did go with this cam I would definitely have the +4 advance ground in seeing as its my daily driver and the lack of torque with the current cam is my main issue. The car pulls like a maniac up high, but my HP peaks right at 6800 where the limiter is set. I want to try and keep HP the same or better but lower in the rpm range and get that TQ number up.

If the LSK lobes give you concern, then you could always run the COMP XE-R lobes on both intake and exhaust.

236/242 .602/.610 110LSA +4

This cam has already had impressive results with XE-R lobes. Check it out:

Trick Flows are supposed to have better P/V clearance milled than stock unmilled heads and this cam clears stock unmilled heads.

I think there is more hidden in your Combo or the 114 duration is killing it.

Very much so. Took a good look at the cam card today while speaking to Vegeance. They were extremely helpful, noticed that the 2 degrees advance were not ground into the cam, hence the hp peak at the limiter. I went over a cam with them that is probably at the limit of what you can put in a daily, but they have seen great results.

239/249 .602/.598 113+2

I decided I am going to lease a car or buy a beater and make this car a weekend car instead of a daily driver. I am going to be pushin it a bit with the 6-point in another car. Plus if I keep modding it I will be renting cars till the end of time. (thanks to State Farm canceling my 94 for the rollbar) I'll finish my 94 at my own pace and make it a no holds barred beast. I still don't think the cam will be toooooo bad though.

Just wondering why are you going with that cam with such a radical lift? Dont forget, cartek 2x cams (224/228) are capable of running 10s with their matching heads yet drive almost like stock. My point is not with cartek, but how small cams with the right heads can make killer power.

Impressive indeed! I really like this idea. I was looking over spec's just last night. These durations and VE's appear similar to G5X3 numbers.

How much would you guess is left in that particular combo through DCR optimization?

Patrick G

iTrader: (14)

Why would you continue to consider another cam that's going to give you miserable dynamic compression and not be matched to the tuned runner length of your intake manifold? That cam will be a turd unless you're running 12-13:1 static compression. Run the numbers and you'll see.

Seeing that most aftermarket rockers are heavier over the valve, which ones have you had good results with? Thanks.
