Z28 Aluminum Intake question...
 

Greetings all....I have a #116 Z-Intake that has the front hole provision for the oil fill tube. Does anyone here know that DIAMETER "ID"? I need to get a freeze plug for this. I should have measured this prior to installation and cant get my mic in there, thus my asking here...Does 1.250 sound about the right size? https://www.yenko.net/ubbthreads/imag...lins/beers.gif

I didn't know that the #116 version had that provision, I know the mold is still there, but didn't think they came with a hole already cast in. Did someone put the hole there, or did they come both ways?

116's do have the fill tube hole. If they didn't I would "clone" mine to a 110. The 116 was the over the counter replacement intake for the 69 Z.

The hole is either 1 1/4 or 1 3/8. It's at home or I'd measure it for you.

If it helps, the freeze plug in my 110 is stamped 1 1/4.
