it's not as critical as some people will lead you to believe. i took my victor jr off of my daily driver, and put on an rpm, and i liked it better on the street. car ran the same at the track. i had alot of compression, what is yours?

not exactly sure but i was told probly 10 1/2 to 1 or 11 to 1

actual ratio is 9.6:1 summit tech helped me with this

on a street car your gonna be alot happier with the dual plane intake. the throttle response and low speed torque is noticeable and nice.

From what I see of your combo,a Weiand Stealth would be a great choice
