Right now I have the comp 228/230 571/573 and from time to time I hear an abnormal tick that could be a lifter so if I end up tearing it down I was thinking of changing cams also. Is the 228R really any gain over the cam i have now? The main reason I ask is because I am hoping to be able to run my current tune since I'm not very good at tuning cams. I had it tuned for the cam I'm running now and it drives about like a stock car would. I had my eye on the torquer 2 but I'm sure I would have to do some changing on the tune. Biggest problem is that there aren't any tuners around here at all. So would the 228R even be worth the upgrade?

You may pick up a couple horsepower, but nothing to write home about. I probably wouldn't mess with it sense the car is tuned so well and you have no local tuners.

Yep. I say leave it too. Not that big of a difference between cams + like he said, its already tuned well.

ok I'll probably just keep the cam i have now then. thanks

It takes a minimum of 4-6 degree change in duration to really make any kind of difference in cam changing. Anything below that and you're wasting your money and time.

Would this still be the case if you're considering pulling out a reverse split 230/227 .591/.571 112+2 and going with a traditional split with something like 228/232 .588/.595 112+4 on a car with nice heads and ported FAST?

You would somewhat be comparing apples to oranges in that case.

In your case you'd probably pick up some TQ going back to the traditional split, but the gains would be minimal. If you've got the PTV clearance I'd go with something more along a 230/236 112+4.

I would think you may pick up some as that cam would be more suited to your setup as you are no longer handicapped on the intake side.

With stock valves, if you've got enough PTV clearance on the intake side, how much more duration can you run on the exhaust side without having to worry? I mean I'd think if my 230/227 clears fine than a 230/236 should be ok too since I'd only be adding duration on the exhaust side?

A 230/236 should clear on stock heads with no problem. I'm not familiar with "Coupe Performance" or what they did to your heads, but if they've been milled at all it's always best to check PTV.

I agree, not enough to warrant the swap.

fully hand ported with a nice valve job, stock sodium filled valves, no milling but I did run .040 gaskets to bump compression a tad and increase quench.

they flowed about 310 at .600
