Better way to go
Better way to go
I have an 84 Camaro SC, 305, cc4bbl, Headman Headers. Everything else is stock, including auto transmission. A friend of mine has an old 350 block in his shed. Assuming that it (a) will fit in my car, and (b) is worth rebuilding, would it be better/more cost effective to rebuild my stock 305, or to obtain the 350 block and rebuild that? Also, if I swapped in the 350, would I have to put in a new tranny? I am not building for a strip car; it is more a daily driver/street machine.
Well assuming that your 305 is in decent shape, it makes a great deal of sense to get the 350 block, provided the block is sound hasn't been bored too much or is cracked (find out why it's just sitting there,) Is it a complete engine or just the block? The 305 is a decent motor but the 350 has a larger selection of hi performance parts at often lower prices than for the 305. The biggest advantage is that you can still drive your car daily and build the 350 when cash and time allows, and when it's ready pull the 305 and swap in the 350. BTW it will fit in your car assuming it's a 350 chevy

350. Don't spend any machine shop money on a 305 block. It just gets too expensive to justify.
Typically, it is beneficial to upgrade the heads to some aftermarket types. World S/R Torquers are a good choice.
Your tranny will fit & work. Click on Pro-Built Automatics above for kits to improve it.
Since you've already got headers, you're on the right track. Everything else should fit, the carb will be fine with tuning. Hope you've improved the air cleaner as well.

By "just the block", do you mean bare, as in no crank, rods, or pistons?
Just the block as in no heads, intake manifold, exhaust manifolds, possibly no timing chain. It has been awhile since I have looked at it. Hopefully, he will be home this weekend and I can talk to him about it.
