Intake plenum volume calculations

We are working on the intake for the 300 LS1 six cylinder project and I was wondering if anyone has some good calculators for determining plenum volume and runner lengths. We will turn this to around 6500 RPM with 3 two barrel (350 cfm) Holleys. Keep in mind that although this is a 6 cylinder, each cylinder is equivalent to a cylinder on a 400 inch motor. Thanks.

Under "head - exhaust calculators" there are a few intake runner length calculators but no volume calculators that I saw.


Now tell us more about this LSx headed monster!!! Pics or links would be awesome. Sounds very inetersting

Thanks for the info. I'll check that one out. Here is my other post with pics. http://www.429-460.com/t12546-ford-300-ls1-6

take a look at the manifolds already in production for the ls1 from edelbrock, also look at the motorsports stuff, get close then start TESTING
