Hi guys, been searching and can't seem to get a handle on this question. I have a 77 Trans Am with a 400 pontiac engine in it. I want to install an LS series engine and transmission. I know I will need to use adapter plates for the LS engine side. Can I just use mounts from a 2nd Gen 350 Camaro? Are the holes in my 77 frame (for the pontiac 400) the same as the holes in the 77 Camaro frame with a 350? I need some schooling...The whole Pontiac/Chevy thing is throwing me a little (I'm not sure if it even matters). Thanks in advance!

I would bet money that the Pontiac subframe has holes already drilled for the Chevy mounts. In 77 Chevrolet used clamshell style motor mounts. I believe Hooker makes an adapter designed for that style of mount. Look on the Holley website.
