Interesting. I'm surprised at how close the curves are on those dyno graphs.

I have a graph comparing all three on the same sheet. I'll post that tonight when I get home. It is pretty interesting.

Jason,

What gears are you running with that TR230?

Thanks!

2MCHPWR: Thanks for the compliment! R&D is alot of fun and it can only help when trying to choose the right cam for a particular application.

MOBE: I was running 4:30s for awhile with all of the cams I mentioned above. I did switch out to 4.56s a few week after installing the TR230 and that is what I used to run the times in the sig.

Jason,

I want to go with the 230 and stock heads (for the time being) with 3.73s. Will that be enugh gear?

MOBE: I think you would benefit quite a bit from 4:10s. 3.73s will work however, but you will definitely be leaving some ET/MPH and some extra fun driving on the table by going with them.

Here is the graph comparing all three cams:

TR 230/224 111 vs. TR 227/224 114 vs. TR 224/224 114

Thanks Jason this is some good info . It looks like the little 224/114 holds it,s own.I have a 224/114 and GTP stage 2s on the shelf.as soon as i get the car to run the best i can with stock internals i will put them on.I want to go 116 to 117 @ full weight first.

Jason--great info! Hmmm.....would love to see the same comparison with stage II heads. I suspect the gap between the 224 and 230 may open up a bit??

Only change was the cam between the two dyno runs.

It's not really an ignition problem. It is just the tach lead for the dyno doesn't read clearly all the time. It happens quite a bit actually. It's time for a new tach lead... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

In all but a few cases, the gains were on par with my car did in terms of the hp/tq vs rpm change between the two cams.
