Thoughts on this cam?? So long story short, pulled out 9 bent pushrods from the engine in this car I just bought. Knew it made a little noise, but I was willing to deal with it for what it is. Come to find a lifter still making noise. Having to pull the engine down that far definitely means cam swap. I will daily drive this car, and wouldn't swap the cam if it weren't for the lifter noise. It is a 6-spd car. I have read for several days on cam differences, and specs. I was wandering about a kit I found. After looking at Texas Speed options, it doesn't seem like such a good deal. I know I am going to do the rocker upgrade while its apart as well.
Here is a link to the Howards Kit I found..

It seems like a decent mild cam but without any info on your car/engine/ &
intended usage...noone can really say if it would work well for you. Plenty of
vendors on here have dead on cam combos for you...EPS, Tick, Futral, and
Texas Speed just to name a few. Research ALOT and spend your money
wisely.

He said it's a 6-speed. Sounds like he just wants something that will drive nice.
I don't know the specifics of the components in that Howards kit, but they make a nice camshaft. And since it's a matched setup, it should make for an easy upgrade. And the cam specs look pretty good for a mild cam. It'll lope and make more power, but with a reasonably good tune should drive just fine.
If you have a lot of miles, throw a new LS6 oil pump on there for $95 as well. Since you have to take it off, might as well replace it.

I am looking for a mild upgrade, car is a 6-spd. Like I said If I didn't have to change the lifters, I would just leave it be. But, since I am tearing it down, might as well do a nice upgrade. The car only has around 60k on it, and bottom end seems solid. Guessing the former owner missed a few gears..I am going to call Texas Speed tomorrow and get an idea of what they can do. I am fairly new to the LS1 scene so I have been reading every night. I have been building hot rods for years, but without the background on the LS1 I appreciate any input. I will let ya'll know what I decide to go with..Thanks for the input..

Personally is go a little bigger.....my first cam swap was a 220/224 and after a week I wished I had gone bigger. Since you are running a 6 speed I'd look at something around a 228/232. Stay at or under .600" lift so everything up top lasts longer and you can just go with PAC or comp 918 valve springs 112 lsa will give you a more noticable cam lope at idle, but a 110-111 lsa would be even more noticable and power would come on quicker in the rpm range.

I have a 223/227 111lsa camshaft that only has 3 degrees of valve overlap and will drive very well, while offering a ton of torque under the curve. With a 6 speed, it would be very fun to drive.

I will try to give you a call next week. I am thinkin about a complete rebuild at this point. If I am going to pull the engine, which I am, might as well go all the way and know what I have instead of wandering..

I hope the numbers in your sig are not for the cam you have listed. If they are then your numbers are very low especially considering yours is a stick. You would only be around 345-350 rwhp with an auto and stall. Actually, those numbers would be pitiful for that size of a cam. It makes we wonder what is wrong with your set up. You should make that power with a few choice bolt on's. Maybe too much cam for the rest of your combo?

I have a self imposed limit of 8-9 degrees of valve overlap @.050" lobe lift for my customers with daily drivers.
If they want a large cam such as the SNS Stage 3 or Polluter I normally warn them many times before their purchase that I do not think a cam so large is a good idea for a DD.
Even at 8-9 degrees valve overlap, you're still pushing the limits IMO as to what can be tolerated 15-20k a year.
A person such as myself, I could DD a Polluter cam because the time would be spent in the tune to make it livable and enjoyable to drive. Most performance consumers and enthusiasts that get a "dyno tune" won't have this luxury to dial in their tune and alleviate 90% of the nuances a large cam can bring to the table.

That is where one learns how to tune an exhaust. 8/9 degrees positive overlap is perfect for a balanced street motor. Also where the overlap falls is also important (my RS cams sound like rapid popcorn roast, the tempo is different than in traditional splits).
