How much hp can you make with vortec heads and combo did you use as far as compression, intake, carb, intake, etc... can they make over 500hp???

I run a 406 on alcohol with vortecs, I do not have any dyno info but I found some flow numbers and pumped the info into desktop dyno 2000 and it goes 500+ for what that is worth.

I have a fully ported vortec motor, with a roller cam, 6" rods, matched intake etc. Only a 357 though and no lightweight stuff. It makes 512 on gas. We've been as high as 13 to 1 with vortecs and have yet to crack one. I know some people have has trouble though. The new beefier ones would probably cure that but they are also probably much heavier. My fully ported Vortecs flow as much as a 220 cc Dart head with only 190 cc runners. Awesome torque. Let's you run more basic bottom end and valvetrain because you don't need to turn it real hard. BTW Vortecs are probably the best 2 bbl head around if you are allowed some porting. If you need some port work done let me know. The guy I use is great and has done a number of Vortecs for racers. Everything is done with a flowbench and he can give you the numbers off your specific set to help with the cam selection.

Just wanted to add that biggest problem with Vortecs is getting High Comp pistons. Have to spend some $ on custom JE or comparable.
