Cool to hear!! That is right around where I want to be on cubic inches I am still leaning toward the AFR, I have seen there small block stuff and have seen impressive flow #'s from them. Thanks for the info !! Do you street drive the car at all????matt mcarthur said:i have a 496 BBC drag radial nitrous car with the afr 357 cnc heads, 5.60's in the 1/8th on a big shot kit... i'm not sure what that is in the 1/4 cuz we don't run it down here. about $8,500 in the motor and it makes 900hp. if you're going to be running alot of nitrous i'd look seriously at the afr's as the exhaust ports are excellent for any type of power adder.
