Quote: I'm not trying to knock what you've done. I hope that doesn't come off that way. I'm just telling you that you should figure out what's wrong so you can get the most out of your combo.
If this one made 470hp to the tire, it probably makes 550~575 at the crank.
Just look at some other combo's. Here is a 340" with unported w9's that made 602hp on pump gas.
There is no reason why your's shouldn't make more power then this. Even if this one has more compression, your heads are MUCH better then an unported w9.
Like I said... sorry if it came off like I was knocking you. I was just trying to help.
Here is the side to side comparison. You can see mine has TQ, theirs has RPM, two different motors. I had to hand jam it and convert it all, so might have some errors, but it makes sense. used 18% powertrain loss.
