TMeyer Track Boss Bypass Plate

I bought a replacement bypass/restrictor plate for my 351C from TMeyer. My machinist didn't install it (they don't run the dyno with a thermostat), so I went to take a stab at it tonight. I am not able to get it to install flush like the OEM plate. Should it? Or is it ok if it sits a little above the lip?

That's a good idea, I will try to reach out to Tim (with my order number just in case). Thank you.

Thanks for sharing those Rock, it's good to have options. My biggest worry is that it would restrict flow to the radiator by not opening completely, like you mentioned. His design is to make sure the bottom is completely flush so that it doesn't recirculate in the block, but maybe that difference is negligible.

In theory, the plate ends up about flush on top. It's possible it is bottoming out. If anything, clean up the area with a wire brush on a die grinder. If you feel confident that it is then pressed in place, but it still sticks up above a little, you should be fine.

I didn't think it was bottoming out based on my initial depth measurements of the plate seat, and so I re-measured it to be sure. While the depth is not flat throughout, the lowest spot I could measure was 0.174" closer to the middle (average was 0.2"). However that low spot should still give 20 thou of clearance if the plate were completely seated. It's possible there are two areas that are bottoming out where my gauge can't measure. (Yes I know it's ugly, I let the block sit too long after the dyno). I'll clean it up a bit as he recommended and go from there.

Yes, thanks for the discussion and the options for it. I would tend to want the altered bypass plate along with the Robertshaw model 330 that it's made for. I prefer a 180* most of the time, and the model 333 may be harder to get at some times, in the rating you want.

Thanks for sharing, another good data point. And good call on keeping extra stock around!
