I have already resealed the intake, valve covers,oil pan and replaced the rear main seal.

Should I be looking at the bearing, chain and bores or should I just put it back in? I am not really looking to spend money but it is out....


What are the weak links in a 302?
As said, replace ALL the freeze plugs. I have seen freeze plugs that looked OK that were basically a paint layer away from leaking. Take an awl and poke on a few that weren't yet replaced and you'll probably see what I mean.

Other than that, I would button it back up and reinstall it.

Richiehd You are replacing ALL the freeze plugs with brass ones I hope. Flush the sludge and rust out of that block with a hose when you have those old ones out.

Torque454 id replace the timing chain atleast. On my 302 I'm planning to replace the bearings and oil pump in mine (althought it knocks on startup) and the timing chain as well as a cam (since I tow, figured a marine or RV cam would be good to do while its out and apart) and headers and all new gaskets and seals, including valve seals. I dont plan to pull the heads or do anything to the bores/pistons/rings, but that may change after I do a compression test.

LATECH It ran good, leave it be. Put the freeze (welch) plugs in it and forget it.
Dont overthink it and fake yourself out.
