Big cam Little cam 427 the larger cam is a 257/266 on a 110 the smaller cam is a G5X3 on a 112. We are going to try 1 more new grind to see what happens. The red graph is the smaller cam. Blue is the monster cam.

It would be interesting to see a dyno run down to 2k or 2.5k RPM. Before I built my motor I spent about a week monitoring on the tach how I actually drove the car and tried to maximize performance in the RPM range where I spend most of my time.
On a street car I'd choose a big bump in under the curve torque in exchange for a big 5k+ HP number - But that's just me.

There was about 15 minutes spent on this tune it was just for r & d only. But honestly we did not think it would put those numbers down. We are going to try 1 more and if it does not work this will be the cam I run. If the next cam is what I think it is we are going to run with that one. Give me about a week or 2 to get those figures to you guys.

Big cam Little cam 427 That is some very interesting and helpful information. Question: Do you have any idea why the blue hp graph goes flat at 6000 rpms? With such a big cam I would not expect that.

We did one for a customer here with a small cam. They are engine dyno #'s, but it did make great torque.

The G5X3 that he has in there now is 234/242 112LSA +4. I'm not sure if your recommendation is going to make a big enough difference.
