6-8 Questions

[86C10LWB]

So the truck currently has a 250 ci sixer that has a rear main seal leaking like crazy and valves? that are making all kinds of noise, lacks power and is generally worn out.

Now I have been giving a free 305 v8, lucky me right, that was freashly rebuilt about 6 months ago.

I wanted a 350 but ill take a free 305.

So the question is what has to change/move in order to swap in the v8???

I have done a half dozen v8 to v8 swaps but never a sixer to a v8.

Go easy on me if this is a stupid simple swap.
