would anyone with a valley mount lift plate be willing to get me some measurements on the valley plate width and length, and hole size and spacing. i don't have an engine yet, but have the materials to make one versus spending 50+ dollars on something i could build in about an hour. i only need the specs from the plate, not the lifting bar since i already have an engine load leveler.

I'll draw one up in cad for you aye..

Damn I'm a nice guy.

Iv been drawing up and making a few ls1 bits over the past few months as they are so expensive to get here in NZ!

All done.

I don't have time to test it but it should be right. Flick me a PM with your email address and I'll send the file through.

Its in good faith.. So don't start producing them to sell Lol.

I know this is an old thread and the op doesnt need the measurements but i wanted to put them out there for the next person. I started out with a piece of plate 1/4 in. Thick 6" x10" long. That covers 6 holes. The bolt spacing is 5 1/8" side to side by 4 3/8" front to back with the holes being 3/8" diameter.

People have been over engineering the **** out of these lift plates. Just buy your typical carb lift plate, drill two more holes in it and there you have it.
