Hi My 70 sport sat came from the factory with a SB and I want to run a BB. Is the K frame ok, do i need special engine mounts or just use standard BB mounts
Thx for looking

Same K different engine mount brackets & BB trans... The engine mount brackets can be found in any Big Block 66-72 C body, B body or E body... Adding a skid plate to the K member to protect the oil pan is a good idea...

Same X member, same trans mount.. Same driveline if you have a 727 trans, if not you will need to shorten the shaft by 4" and get a 727 yoke for it.
