I am planning on building up or rebuilding a 350 4 bolt. I plan on using the same injection system (TBI) that is on my 305 I have now. So my question is for all the "Swap Masters" on the board is, what parts am I going to need to buy extra or what is useable like exhaust manifolds, accessories, etc?
Thanks in advance for your input.

Everything from the 350 can be transfered over to the 350. I would not reuse the 305 heads, intake, cam, or exhaust manifolds. They are all garabage and will make your new 45 CI gain not worth it.

This is what you will need though.

350 TBI injectors
350 ECS module
350 knock sensor
New Chip (get ready to burn your own). Depending on how radical your heads and cam selection are you may be able to get away with the infamous "cop car" chip for the time being. Take a look at the TBI board and read the threads posted at the top. They will tell you what makes TBI set-ups tick.

 

So I heard from a few people that the heads, and intake manifold, and intake are the same from the 305 and 350's.
Thanks

 

The cams are different and the intakes are pretty much the same (similar castings but different GM part numbers). The heads are not the same. Both are smogger swilr port desings but the 305 heads have 58cc chambers and the 350's have 76cc chambers. Everything about the 350 TBI sucks just as bad as its little brother. To make it a performer you need to replace everything but the shortblock.
