Need to know cam duration....lift tells us nothing. Just taking a guess from the lift #'s, is it a comp xr288hr (236/242)? If so, that should get ya over 500fwhp with those AFR's. I'd run a 750cfm double pumper and 1 3/4" headers if you can, might also look at 1.6 rockers.

What is the weight of the car you'll be using this in?I'd say mid to low 11s depending on traction and weight. I agree the 1-3/4" headers, a dual 3" exhaust and 750 dp carb should be what you use on this.

hey hows it going, im doing a similar build with a 406. what fuel system are you going to run? i've been running a holley red pump- way to weak for this motor im sure, but im not sure what pump, hoses, regulator, etc i should be running. im aiming to make ~450 fwhp. any advice anyone can offer on fuel systems would be great, thanks guys

More compression. More camshaft. Bigger exhaust. Ditch the stud girdle. You wont need it. Hydraulic roller springs dont have enough spring pressure to cause the stud deflection that girdles are supposed to prevent. We're running hyd rollers right up to .650 lift with nothing but good studs and rollers rockers. Hell, for that matter, we run solid rollers over .700 lift without girdles.

Here is the link to the 1/4 and 1/8 mile et calculator - I did not know what driver weight to input. The simulated dyno run looks like a really good combo. Nice torque curve and plenty of power.
