305 to 350 swap

[arobs23]

Hey guys!

 

I have acquired a 350 to replace my 305 in my 86 k20.

 

Just starting to prepare and plan. Need to purchase parts.

 

Any info/parts lists/advice?

 

Also, any info on this casting number and the quality of the block?

Pretty much all the same parts.. Carburetor jetting change or different carb would be necessary.

DONT THROW AWAY ANYTHING.

 

transfer everything from the 305 to the 350 but use the carburetor that came with the 350 because it needs more fuel. THEN< put that 305 on a trailer and take it to the nearest scrap yard immediately. They were garbage.
