conversion mounts readily available
multiple headers available these days
tons of radiators out there these days that will work..
back when i did mine tti weren't around yet so i went with the pro parts headers.. really nice header but partial fenderwell.. today depending on my build i'd schumacher or tti.
mounts i'd just go schumacher for whatever k-frame i have. yes transdapt sell for half the price but after using transdapt for my small block they are half th equality as schumacher too..
when i did my big block years ago i just used a recored small block 22" radiator.. they put a stagard core in it.. worked well.. now there are tons of aftermarket radiators out there that will work..
