Hey fellow Chevellers, can anyone help me with a part # or a place where I can find a 1 In. Q jet 4 hole spacer? Looked and can not locate one all I have been able to find is an open spacer. I have rebuilt my 1972 402BB to 423HP 495 lb ft torque. Haveing Sean Murphy biuld me a new Q-Jet to match. I am also still using my OE intake for show purposes. that is why spacer is needed and do not want to loose low end torque with open spacer any help would be appreciated!

I was told buy engine builder who dyno'd my motor that a 1 in spacer would increase the horse and torque because of my OE intake very low. What are your thoughts?
