I am going to be ordering one of these cams today, but need a little more info. I realize with the TR224 114 I will have to change back to stock come smog time, but how much HP over the TR220 114 will it make? I have heard from 4-10 on stock heads, but is that peak or is that from 2500 up or what? Sorry for all the cam questions in the last couple of days I just don't want to switch out cams two or three months from now because I am not happy.

You'll gain about 5 more rwhp above 5000 rpm with the 224, but the 220 will have anout 5 more rwhp below 3000 rpm.....

I didn't know that...and here I was beating myself up because I ended up going with the 220 instead of the 224...good post.

With LS1 edit tuning you should be able to run either cam and pass smog. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

I was told by Pual @ TR the 224/224 would not pass a emissions test. It depends on where you live

When running those cams, what would you shift at between the two? and what about at a 112 LSA? would more power be gained w/ the 224 just b/c you can shift higher?

I gained 10hp from 5000rpm and up.Nothing in the lower rpms on the dyno,but I could feel a real difference down low.
In Massachusetts we can pass emissions with the 224 Cam because they just switched to plugging your car in and checking for codes.With Edit you can loosen up the misfire codes and raise the rpm to get the idle to smooth out.I wouldn't be surprised that it could pass a roller smog test.

My car with the TR220/114 makes 380 rwhp from 5700-6500 rpm, plus or minus a few. I shift around 6500.

Thanks for the help everyone. I decided to go with the TR224 114 and just worry about smog when the time comes. It should be here by the end of next week, so I will have something to do for the holiday weekend. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
