I say go for it.. Those XE-R are crazy! Didn't you geta cam card? I put a 228/228 .588/.588 111 + 4 in my 6.0 H.O. into my 1999 Z28.. It idles with a vig 3200.. Just bumped the idle up a little.. I need tuned badly though..

 

I wonder if that's the GTP 420 I sold to WMsupersport Wes I think? and his buds?? This is an older lobe design.. Bad *** cam though..

 

bigeller, that's the one. wes and keith are two good friends of mine.

 

OK, I have gotten more nahys then yahs on the cam so far and I agree that it is a little large for my truck but... The guy that is selling it also offered me his TR 220 .553 114 instead. Although that is much better than the 224, it is still not a great truck cam. I will actually talk to him in person this afternoon so I will have more details.

 

I just put a 215/215 cam in my 5.3 and made some good power...problem is I have to really rev it up to get to the power. 6200rpm rev limiter needs to be 6600rpm.

Here's the dyno graph..you can see where ti just keeps on pulling even at 6200rpm.

big, i was going to put that exact 220 cam in my 5.3L! i think it'll run ok

 

Verdict is in... another one of our f-bod friends wants the cam so I declined and let him have it. So I am just going to hold out for the custom grind I have been thinking about. Thanks for all the opinions guys.
