are you going n/a or planning on supercharging or turbo charging it ?
weve done 1/8 and 3/8 th's because that was what we had.
are you using part of the upper as a base ? 302 uppers work better. larger ports
I posted some pics once will try and find them or will take more of the one in the basement.
I have found the throttle body attachement to be the hardest part for me to fab so on this one i bought a egr space and welded it to the box.
good luck have to drive Amber to work.
