Need some ideas to get measurements inside the upper plenums of intakes and caliper ?

Hi guys,

I am looking for a typical caliper that can measure port dimensions, so a range of 1/2 inch and I should no need no more than a 3 inch for the other dimension. I figure this should be no problem, since I have seen calipers vary greater than this. Any good, cheap, and accurate digital calipers?

The main reason why I made this thread is to look for a "special" caliper that is flexible or ideas to assist. My goal is to get port measurements INSIDE the various upper EFI intakes.

I see two options for entry. Either from the runners from the bottom, or go through the throttle body tract and around to the ports. Impossible? Possibly, but I am looking for ideas to get the height and width of the port openings in the upper intake.

Either some "rigging", method, or a certain measuring tool I am not aware of to get these would be nice to know.

Thanks for any ideas.

Sounds like what you want is telescoping guages. Thay are spring loaded and can fit in alot of areas. Once you get them locked down, pull them out of the port and measure from tip to tip with a caliper or a micrometer.

Good start I can use those to find minimum port dimensions.

I got to looking at some of them online, and it does not look like they can get 6-10 inches into a sharply curved port, like an upper intake would have.

I found a 6 piece set for around $50.

Any other ideas for some flexible types?
