If my math is right, you have a 498cid stroker. Your best bet is to find someone with the "desktop dyno" program. The only way I've ever seen to get an accurate horsepower rating is to go by your truck's weight and ET. Whatever you find out, I'd bet is some pretty serious horsepower. Nice build, Brutha!

As far as cubic inch, that is pretty close to where I thought I was. The cu. in. limit for my class is 496, but they allow 2% if pumped. That is pretty close to where I thought the horsepower would be. The torque numbers seem pretty good and that will definately help when it comes to pulling. I've been trying to get it around the 700 hp range, but I'm restricted to running cast iron or factory production aluminum heads. I spent a decent amount of money to get it where it is at now. I want to run it this season and see how everything goes and then next year spend some more money and try to get a little more out of it. I know head work always helps. Just to pick your guy's brains, what would you guys add or do different??
Also, I saw Trick Flow now has an intake that will fit on the factory production heads. Has anyone used this intake?? If so, what did you think??

you dont have to go with the TFS, a victor is just as good. i think your set up is good. i basically have the same set up just a little more cubes.i would leave it alone untill it breaks. you can get a little more by throwin another carb or a bigger one but see how it works this year..
