Well i sent my block off to the machine shop tonight :D Very Excited! I know it can be done but have a few questions. I know to use the full length hooker comp headers for g-body. Its still a little cloudy for me as far as what to do for motor mounts.....? I use the stock mounts that are one the crossmember.? But i use bbc mounts on the engine side?? correct me if im mistaking....? Am i missing anything? I am strictly looking for answers to physically get the motor in the chassis not I need a hell of a rear end or trans lol...jk but really though strictly motor related responses please. Thank you Zach

I am putting the same power plant into my Regal. I was told by people who have done this swap that small block chevy mounts, similar to the Monte Carlo SS, will work just fine. Did you keep your airbox in tact? If so, watch the clearence with tall valve covers.

Good Luck!! Post Pics when it's in..

Unless the stock bore has already been bored .030"-over you're not going to end up with a 468. Not trying to burst your bubble or anything just want you to be aware of that - if the 454 hasn't been bored .030" over already then you'll end up with ~461c.i.
