2.8 V6 to SBC 350 question

I'm getting ready to start this swap in the summer but with tax time around the corner I was thinking of getting parts now. My question is which parts from the V6 can I use on the 350? Thanks guys, and I will post pictures as I go, I will also be painting this summer lol

Re: 2.8 V6 to SBC 350 question

are u doing a carb swap or fuel injection swap?

nothing from the v6 can be reused including the transmission
u have to change the front springs to v8 springs and also change the engine mounts

u will have to change the fuel pump in the tank.modify the sending unit to use a mechanical or low presure pump

or u can leave the stock pump and run a return style regulattor to ring fuel presure down to 4.5-7 psi
