Anybody have a front and mid motor plate for 409?
May dragster broke both my rear motor mounts. So time to get serious about controlling horse power.
Does anyone manufactured them, as far as a company....????......What thickness of plate is required and is it a specific type of aluminum sorry for so many questions

For the front I'm looking at "U" shaped plates. Are the 409 front motor mounts spacing the same as CSB and CBB ?
Looks like the universal rear plate will work.

Howard this is a pattern from my rear engine dragster from back in the early 2000s that i modified to fit the recent altered i put together. I took that motor plate from the altered and cut off the outside ears and welded on new ones for the latest door car. You would be welcome to this pattern if its something you can use. BT

Your sure welcome Howard!! Here’s a better explanation of my a/c as i call it!! I can’t tell you how many times I’ve been in the staging lanes suited and buckled up waitin to make a run and someone drops oil or stalls on the track and it’s 100 degrees and 60+ humidity that day or night in Texas. Well...... i just turn my 275 to 300 cfm bilge blower on and it will give you cold chills until the sweat dries! It draws in the outside ambiant temperature. Very refreshing. There has been one in my old Nova for over 25 years. Doesn’t draw very many amps. Not expensive from Summit by Allstar performance. 4” od.43B11A98-C38E-440B-9C93-B55EFEEA87A2.jpeg41C63FE9-5366-4252-AF59-93AD84DDBBF3.jpeg

Just bought this and was curious about the motor plate so I was doing a search and found this thread. Gonna use it in my 55 and the ends have been hacked on. It’s a neat piece for sure.

This is what I used on MY "Joint Venture " swap It was a modified HURST front mount

Thanks for all the great ideas. I used the Hurst front mount idea and welded on new ears. the front was easier than the rear plate. I did find out that 409, stock front engines mounts holes are different from big blocks. The last race at Toutle, put another push rod thru the rocker arm, and now am pulling rocker arm studs, so putting in screw in rocker arm studs this winter.
