Default replacing 228r

Before my heads and cam are installed I wanna see if there might be a better cam for me. I currently have a 228r on a 114 lsa and have been reading a lot of comments about leaving power on the table and how harsh it is on the valve train. My heads are prc stage 2.5 ls6 and are milled to 60cc. So what other options would you guys recommend. Car is a weekend cruiser ss3600,I chose the 228r on a 114 because I want good all around power and excellent street manners. I'm afraid that with my heads being milled so much it might limit my cam choices. I'm sure a custom cam is the way to go I'm just curious as to what everyone else is running with a similar setup.

228r is a good cam that's proven itself for years, if you already have it and it's in good shape no reason not to run it unless you want to go max effort for your combo

you wouldn't want to go bigger than low-mid 230s due to drivability and ptv issues anyway

I like my EPS cam a lot and I know there are a lot of happy users out there with 230/234 and 230/236 versions of it as well. I think a few have 228/232 too. I dunno how much clearance you have as I am not a build expert.

I'm also sure Martin at Tick could hook you up with a Torquemax cam, I think he has one in the 227/230ish flavor which would compare if it fits.

Just depends if the loss you will take on the cam you already have is worth it to you

I make 460 hp to the tires with those same heads and a 228R. You go bigger on the cam, expect the power band to move up and bottom end power to decrease.

I feel the 228R is already less than ideal for low end torque....I would not go bigger unless I had more cubes.

Im happy with mine. Not sure if a 224 would make more down low, prob not.

I made 418 RWTQ with 224/228 .581/.588 110 +0. For a street car power under the curve is far more important than peak power. HP is for show torque is what hauls your azzz.

TEA 5.3 heads milled to 59cc chambers. Compression is 11.4 to 1. They flow 316 on the intake side.

Wow, look at the exhaust flow on those heads too!

The combination of the smaller intake runners maintain a high velocity intake charge at lower RPMs. Combined with the good flowing C&C porting with the high compression small chambers make for great throttle response. Great torque all through the power band. Peak power is at 6300 RPM. Which is right where the intake starts to run out of breath. I make 375 RWTQ at 3200 RPM.

True, you want to build the car for it's intended purpose. That being said though...I don't want my @ss handed to me in the 1/4 mile either. I think the 228R was a good compromise for an all around ride. More duration would have given me a few more peak hp #s but not much to complain about. You also have to consider cams that have high lifts also beat the springs up. You will be changing them out sooner than if you went a little less aggressive on the cam.

Ramps are what kills springs too, its all about rate of compression.

I would love to have that torque. My intake falls off around there too and I have no want to spin higher.

I may have to try a combo cam like that and I am going to give TEA a call to see more details on their cyl heads.

They seem to be the biggest flowing exhaust heads I have seen... but wouldnt that cause an issue with bottom end? Strange...

I have a comp cam 228/230 it is a great dd and very similar to your 228r. with the wright tune its very responsive even at 2000 rpm. I would run that cam. you should be happy with it. I am glad i did not go bigger. It will make a fast street car, weekend warrior.

I don't go to the track anymore. But on the street I don't go looking for a race but very seldom does anyone hang with me. I change valve springs at 50,000+ miles. (dual springs) When you start running cams with duration above 230 you have make a lot of compromises and drivability suffers. Been hot rodding for 50 years now. I have a pretty good idea on what works and what doesn't. I had a plan when I put this combo together and it has worked out just fine. I learned along time ago if you go to the race track take a phuchin race car with you....... These LS series engines make plenty of muscle without going over board on a cam. Bigger is not always better.

I ran 11.72 last week with my full body weight ws6. The DA was 2800 ft. With good air i should run mid 11's.

Here's a few custom CompCam options you could go with :

229(lsl)/229(lsl) 114lsa, lift .615"/.615", 1* overlap
229(lsl)/230(lxl) 114lsa, lift .615"/.609", 1.5* OL
230(lxl)/230(lxl) 114lsa, lift .609"/.609", 2* OL
227(lsl)/230(lxl) 114lsa, lift .614"/.609", .5* OL
227(lsl)/227(lsl) 114lsa, lift .614"/.614", -1* OL

Current cam : 228/228 114lsa, lift .588"/.588" , 0* OL

Also....
Cam Motion # C33-712, 228/232 114lsa, lift .578"/.578", 2* OL

Futral, F11, 228/230 114lsa, lift .576"/.595", 1* OL
F12, 230/230 114lsa. lift .595/.595", 2* OL

Why do most use 114?
