I'd say somewhere in the neighborhood of 500 crank hp...... 12.60 1/4

I will be running a holley black pump with regulator do you fellas think that enough fuel.

You will be fine you can even go with a blue. I have a buddy running 11.70's on a red. I am going 11.18 on a blue.

Thank i thought it might i had almost the same build in my old s10 and detonated the motor by either not having enough octane or not enough fuel that build had 11.1cr with 64cc iron heads plus i had a red pump with a regulator a no no!

Even with the 10.3 compression ratio make sure you have a good quench area. As close as .040 as you can get with save piston to valve clearance and pump gas should not be a problem. You don't want to detonate another apart.

i'd say 450HP range like others
