Hooker makes a set to swap an LS1 into a chevelle but they run about $500 and are made to work with the S&P style engine mount adapters. Hope this helps.

S&P... Is that those that move the motor closer to the firewall ?

I would never use a mount that mounts the engine to one location. Its the same as arranged marriages. I always play with the engine mounts to get the best fit. I guess thats why I like the BRP mounts. Lets you weld the mount into the best possible position. The Hooker headers are great, they even worked on our 70 Olds 442 that has a 4L80E. I thought for sure I would have to trim on the bellhousing but we didn't.

I used the complete frame, engine, and trans mounts from brp. I have about 3/8" of clearance on the alternator, and oil pan, using f-body accessories. All we had to cut out is for the ac but it was ez.

I dont understand why I should have to changer the frame mounts... seems like everybody gets by just fine with the stockers....

Plus I already bought new Energy Suspension SBC mounts for my project.

... Do you have pics of you setup ?

Everything depends on your goal. I like to use all f-body accessories in the stock location. I also don't want to cut the oil pan. The BRP mounts also work with the Hooker headers. I'm have no experiance with using the stock SBC mounts or frame mounts. I know the S&P plates make you reuse you stock frame mount. I you have those I don't see why you couldn't slide the motor back and weld them into place.
