Who to go with for custom cut engine plate?
Either way, since the engine plate is the next biggest step in my project before I can move forward, I am looking to see if you guys have any recommendations on other engine plate makers that can do custom cuts to fit my application.
Let me know.
Thanks!
Hardest part for me is finding an engine plate that has threads at the water pump mounts so I can run fittings for a remote pump. Most plates have the square openings, which I wouldn't be able to tap.

Most plates also look like they only mainly use the 3 10mm water pump bolts to hold each side of the engine. I'd probably want them to attach to more points around the alternator/cylinder heads as well, just for peace of mind really.

For example, this kit would still work, although you may just have to buy slightly longer bolts is all.
Also, the adaptors from what I've found all almost cost as much as the mounting plate itself haha.
One last reason is also the simple I can make it the better. Less gaskets and pieces will mean less places that water can leak out from, etc.
For the steel bolts, I'm not really worried about them breaking as much as the extra stress that the smaller aluminum threads on the block may have to deal with. Probably a moot point anyways, cause if everyone are just using the water pump bolts, then it probably means it has to work.
Like you I wanted all the bolts. And even made an angle bracket for the lower passenger side that catches two block bolts and the engine plate and made some spacers for the passenger head
Here are my construction pics. I made a template from the timing cover gasket to route it into the plate itself. A small trim router will work and I bet you can field cut the depth which is like .045 iirc for the drivers head
1/4 inch alum should be more than plenty to tap for an oring boss fitting for the water jackets. I've since installed the Mezzire street pump and love it
To seal the plate to the block, I used my diegrinder and cut in like an oring groove around each port and installed it with black rtv silicone. No leaks in 1.5 years
Edit, I also did a mid plate from 3/16 alum. It bolts to the subframe and the upper firewall area. My ish is locked in there good!

I made my template today and going to go to the local water jet guy to see if they can cut it based on my drawing/template.
One thing I noticed is that the water pump openings are roughly 1.25" in diameter. However, it seems like most people use -12an or 3/4" fittings on there? Is that too restrictive or what is the consensus on that?

I think -12 is fine, I feel the restriction in the thermostat is greater, along with the head gaskets

I want to do a NPT tap, but not sure how I can properly get the taper to tap on there.
