LT1 install, what clamshells?
In order to install an LT1 into an 86 IROC, what clamshells need to be used. The engine has F-Body accessory brackets and an AC delete pulley, so fitting the compressor isn't an issue.
The IROC has the original rubber mounts on the K-Member still, but the clamshells that bolt to the engine are not there. I have new Energy Suspension engine mounts that I plan to install, but I need to know which clamshells I need to get to bolt into the IROC.
The LT1 I'm using is coming out of a caprice, so it has normal GM clamshells on both sides, but isn't the passenger side too far back? Is it offset to move it back, or are there 2 mounting pads on the side of the LT1 block?

yes, there are 4 holes, only three are used for either mount, just use the pass side clamshell for the third gen

I have another parts car (but I only for another couple days) so I'll steal the complete mounts from it before I kiss it goodbye just to make sure I have everything I need when swap time comes. Thanks for the help.
