1954 Chevy inline 6 (235cid) engine specifics

Guys I am developing a model fot he chevy inline 6 engine for a project at school. I am going to run an engine simulation to determine certain performance factors and possibly some emissions values. I'm short on time so I need some quick values for the stock engine.

I need to know the intake port size. But I need the diameter size of all the junctions. So this would be the intake port then the run diameter leading to the intake port, then the diameter of the y junction for the two ports.

I need these same values for the exhaust side.

I know this might be asking for a bit much but: what about the radius sizes on these manifolds

Internally: I need the connecting rod length
and clearance height
Is it safe to assume the wrist pin offset is 0?

I searched and even emailed some engine companies to try and obtain these values but had no luck.

your better off using a diffrent engine.. I might be able to give you the connecting rod length, deck height and piston pin offset and valve size, but that's it.. I'll have to check my manual ( '53 Motors manual ).. the other stuff you need, nobody is going to have, and my book deffinatly doesn't have it

Wow, you are asking for a lot of info that GM probably doesn't even have anymore! LOL And you need it all yesterday? Looks like you'll be doing a lot of "fudging" on numbers in your spread sheet program tonight! LOL.
