Default LS1 Motor mount plates, prints?

Does anyone have the dimentions for motor mount adaptor plates? There was 2 pics in one of the FAQ's but both links were no good. Im going to make a set and a print would be gratefull. Also any first gen camaro guys here have the dimentions for the 4 sfront sub frame mounts, im goin to spin up a set of aluminum ones once i get the dimentions. Need to change them while I do the ls1 swap.

Thanks guys

The 3.125 dimension on the motor plate drawing is incorrect......It should actually be 3.070.......(78mm)......ask me how I know......LOL

Strange that print shows the holes at 9/16", seems way big to me. Bolts are either 10mm or 3/8", both of which are smaller than 7/16". Also, wondering where these mounts will place the bell housing flange in relation to a traditional small block? Also, just noticed it calls for the third hole from the left, at the top, to be countersunk for a flat head bolt, pretty sure it needs to be the second from the left, as that one will be underneath the motor mount.
HTH, Jim

I took a LS MM and traced it out, then measured 1" forward (engine set-back) and used a SBC 3 bolt MM and traced it out.
Then I just bought a pair off Ebay for $40 but they came PC'd and with bolts.

Anyway....

yeah, that design is wrong. I addressed it in the "LS1 Swap FAQs" thread. You can see where the countersink should be in S&P's instructions (second photo down).

For anybody else like me who might look for this info.....

The hole spacing is incorrect as pointed out by Kwhizz, I too have just had my laser cut plates back to find they don't fit. It was then I came across this post.

Attached are the right dimensions for the block mounting holes.

Hope it helps.

I found this a while back. Hope it helps. Worse case you could use a set of screw spotters or a piece of cardboard and a ball peen.

Using inches to dimension a metric motor doesn't exactly build credibility.

If you're using an f-body pump for the straight out water connection, just switch to a LS3 gen5 camaro pump. It matches truck accessories and the outlet points forward.
