400 t/a motor into a1983 Grand Prix

[Chuckles87blue]

I have seen a few post of how to put a 400 in a g body I think I need 301 motor mounts but do I need the 301 frame mounts or do I need the 301 engine mounts? I have the mou ts off of my 1977 400 for the motor will those work if I just buy 301 frame mounts I hope some one can tell me because I see there is a left side engine mount for a 301 on eBay but if the 400 engine mounts will work I will just buy the frame ones. I. And I can buy those Anytime

I have done the swap using G body 301 mounts. The Firebird mounts look the same but have been told they are a little taller and will raise the engine some. I haven't used them so can't say for certain. And as you said the frame mounts are readily available.
