LT1 to LS1 swap
Hi Everyone,
I am swapping a LS1 into my 97 Trans am and I would like to keep my stock k member and use motor mount adapters. Has anyone used the adapter plates and been able to use stock LT1 motor mounts?

I don't know if what you're looking for exists, but Hooker offers mounting brackets that allow you to use 4th-gen F-body engine mounts with your stock LT1 K-member.

Fyi
The lt1 motor mounts will not work, but one nice think on your 97 k member there is a hole on pass side you place the top forward hole of ls1 mount there and you can thread that hole the other forward holes you drill just use a socket with a extension on it . You can also put the nut on top . the rear top you have to drill through both parts of k member . No special drill bit is needed. On the bottom rear bolts I used well nuts. Some call them rivet nuts. I beat them down so the motor mount was flush. To save money all truck accesories and water pump work great . Don't listen to everyones bs about needing f body brackets 2001 1500 work great.

Here's a couple of images of the Hooker engine brackets for the V6 K-members; the LT K-member versions are similar. This configuration puts the LS engine in exactly the same locating it sits with the LS1 stands and K-member, which ensures compatibility with any headers, oil pans and other components that are designed for stock LS1 4th-gen F-bodies.
