Big Block motor mounts ... TH400 tranny ... better radiator(just my .02).
You will need new exhaust of course ...well headers at least. -Hart

Re: Big Block Engine Swap
Many people run into firewall issues, but some don't. Some beat the firewall in for clearance, others move the engine forward a bit. The 4x4 subforum has some posts on this. I choose to modify my firewall and I added a body lift to fit my bbc.

Re: Big Block Engine Swap
I put a 454 in my 72
 The SBC engine mounts will work with a BBC. The bell bolt patters are the same between SBC & BBC but I wouldn't recomend a TH350 behind a 454, a TH400 is a much better match. I have a SM465 manual so I don't know anything about autos. Other than the firewall issue and header fitment issues the 454 is a bolt in affair. Oh and swapping a 3core rad for a 4core is needed too. I left out alot more info on how I did it but my swap was not basic but a BBC will drop right in for the most part.

If you do go with a manual tranny I recomend the SM465\NP205 combo, strong and hell and very reliable.
