On the STR build 9 and all the big displacement builds), I modified the throttle bodies and stacks.
Specs are..
38mm intake
41mm throttle plate
46mm stack tapered down to match the 41mm throttle plate.
On the more competition based builds I use 2.2 MFI stacks and Throttle bodies as I can get much larger.
42mm intake
44 throttle plate
52mm to 44mm on the stack and run PMO 50 Air horns.
I have also stopped using the steel fuel lines and have gone to plastic. The heat from the heads are heating the lines up all the way to the injection pump and the modern fuel is not formulated to take the heat. The cars a dealing with vapor lock during high ambient temps and short stops like filling up for fuel. The plastic lines help with this tremendously.
