I bought these plans off of ebay and built this for a Jag project and for the 302 I'm putting in my ERA.
It's adjustable and from what I can tell, it would work for any make of engine. The pix are a V12 Jag. I'll just change the engine mounts and reset the spacings for my 302. It will easily hold +1500 lb and is well designed. Structural members are all .125" wall. The legs extend out for better support during testing. Plans have wiring diagrams for tach-
oil pressure-water temp, materials list.
By not buying it retail, I was able to afford a Millermatic 180 with which to build it. $8.50 for the plans and about $225 for the materials (including gauges, although fuel pump for efi would be more)
