My century has a 301 v8 and I’m going to put in a sbc350 and turbo 350 trans. I know I need different motor mounts but besides that should it be a pretty direct swap?

Not sure if the trans cross-member would be different, even if you have the THM-200 now I think the crossmembers are the same. Other things to figure out of course are the exhaust and fuel lines that surely will need to changing or replacing going from the 301 to SBC.
I would be interested in your engine side motor mounts if you wanted to let them go. I’m putting a Pontiac 400 in my 86 Grand Prix and they are the key to make it all happen. I’ll try to send you a PM as well.
I’m not familiar with where/how the 301 fuel lines are run, maybe someone here can chime in. When converting from a 3.8 Buick to SBC I kept the stock feed line and connected proper fuel hose and some aluminum hard line I could bend to run on the frame to the fuel pump. I would think whatever lines were on the car you can probably do the same, with low pressure (non EFI) pumps I think there is more allowance.
Also wouldn’t think a 301 pump interchanges with a sbc if that’s what you mean. For how cheap new pumps are I would suggest that they even if it does fit, a stock application mechanical pump will support a mild motor and then some.
