BI 305 to 350 engine swap

[snowbuzzard]

Just lunched the 305 in my 87 4x4 1/2 ton, had a quick question. I have heard that when swapping from a 305 to a 350 TBI that the injectors and everything are OK, just need to swap the computer. I have also heard that these old OBD1 TBI's don't require a computer swap, that all is ok.

I'm thinking of swapping in a long block 350.


Looks like the timing turned and advanced it so far t shook #3 piston apart. There's water in the cylinder also, so it's most likely pooched.

Anyway, thanks in advance for any help, been reading the forums for awhile, so not quite a newbie for the first post.
