I took a few measurements and gave them to Keith and didn't have to trim,cut or anything. Piece was perfect. It was well worth the money instead of trying to mock something up and "fabricate" it myself. jus sayn

I agree - and it looks great. But having said that, I can also say the individual head plates will work. The previous owner of my car used the individual plates - and about 12 years ago when I moved the engine back a couple of inches I just went ahead and used the same system - my car has made a whole lot of passes down the dragstrip that way. I think one of the reasons it has worked for me is that I have a real good mid-plate. If I had known then what I know now - I'd have a plate like yours - and I'll end up changing mine at some point. I do think it is the better way to go - but it's not the only way.

Just recently we did some dyno testing with an LS7 Chevrolet Super Stock engine.
We tested it with side engine mounts and then with a front motor plate ... then again went back to the solid side mounts.

Lo and behold, the engine made 7 more horsepower peak and 5 average with the front motor plate mounting than with the solid side mounts. All we could figure was that the side mounts were actually distorting the bores a slight amount under power.

Now, the LS7 is an aluminum block so, a sturdy iron block may not see this however, it is something to think about when making near 1,000 horsepower.

Interesting info Randy....
Goes back to the old trick of putting an inside mike in a bore with just enough tension to keep in in place...then squeezing the block externally and watching it fall out.
Thanks for sharing..
