273 302 318 340 build
Ok so had dad looking over my shoulder today and had success.
Got cam out the front. Bearing wasnt spun. Just didnt hold my tongue right when pulling it out.
Came out fine looks ok? Some.varnish spots. All bearing oil holes lined up.
Next onto rounded head bolt...of.course it was the middle lower one that is "shrouded" fer frig sakes.
Able to take a grinder to it and hammer a 11/16 wrench onto it and get it out. 2 for 2!!
Heads are 4027163 casting big valve heads.
I will dismantle valves/springs.
Maybe reuse the springs?
Then flipped her onto her belly and took her pan off.
Pan looks brand new, Bonus!
Nothing stands out as being an issue with bottom end.
Im at the.point on the 318 where I dont want to dismantle anymore. Not saying I wont but if I remove pistons or crank them I may as well put new bearings in. Agree/disagree? ? If I do its more $$
So now is clean/inspect and start a list. And do some research lol
I dont think you can enlarge the 302's for larger valves 1.88 and 1.60 cam you? Machinist said not enough meat there? Correct me if we can.
BUT here is the kicker with machining....
$230 to recut/reface valve seats.
$10/hole for valve guides
$65/head to resurface head-block surface.
It can add up quick even if.they come back crack free.
Thanks again guys, bit of a hectic day and not a lot of time to read/comprehend todays replies lol.
Good day tho going 2-2!
