Not sure if I should post this here or in the internal section, but I need some specs on our truck intakes. There's 3 main things I need to know:
1) Intake runner length
2)Square inch area @ the beginning of the runner
3)Minimun port area (cross section) in square inches

I'm going to use this info, along with my SW long tube specs (primary dia, collector dia, primary length, collector length), Bore, Stroke, Rod length, Head flow data, CR, desired operating RPM, etc., and plug it into some software that my father has to help find some custom cam specs to meet my goals.

Any help would be greatfully appreciated

 

I found that the runner length is 263 mm. Runner volume is .541L.

 

Thank you

 

Anybody have any more input as far as the square inch area at the beginning of the runner, and the minimum port area in square inches? I can convert the runner length numbers from mm to inches, but I still need these other specs to punch into the software.

Thanks in advance!

 

There's no way this is true, but you could just assume a constant cross section and back the the area out using the volume and length. I got 205.7 mm^2 = .319 in^2. That's back of the envelope, though. In any case, save your self some time by using this unit converter.
