Dumb, did it get hot? Or did you put the turbo on?
Oh nice!! So not this bad….No overheating or turbo.
Leaked coolant externally. First noticed it about 200 miles after the rebuild. Was hoping it would quit leaking but just got worse. Bad enough now it runs down the lifter cover down the bell housing. Turns out I used a not very good sealing gasket. Guys over at fordsix told me to use a felpro 1024 and not look back! Lots of cleaning to do on the gasket surfaces and then it's back together.
Oh, the new head gasket is a steel centered composite layer type. For forced induction and stuff ...

Tried a different head gasket and used 518 around all the coolant passages. Figured if it's good for a greasy old saw it should be good for a clean deck surface.

Head torqued down and a little 518 is squished out so I hope this does it.

Been meaning to try a different style of spark plug for a while. Went with a fine wire iridium and standard reach instead of extended. We'll see what happens.

Made it to here till the caffeine ran out. Egr tube and upper manifold and some coolant is all that's left!

Awesome Steve! Am curious how those plugs work!! Keep us updated!Tried a different head gasket and used 518 around all the coolant passages. Figured if it's good for a greasy old saw it should be good for a clean deck surface.

Do you remember felpro blue brushable gasket sealer? Was thick and stringy like permatex hightac.
Long story short I got the bug to swap the heads on my plow truck years ago. Got the damn thing all stripped down and the gasket set napa had dropped off was for a 351 ford.......
My truck was 350 Chevy..... 9:30 Saturday night when I found out. Said fudge it. I pulled the old gaskets and gooped both sides with the felpro blue and put it together. Ran it for six years like that! Ended up scrapping the truck but still have the motor sitting on a stand. Going to put it in something fun one day. Or more than likely another plow truck.

No, I sure don't not. Sounds like a good product though.
Was talking to some 300 builders about a spark knock issue I have been having under heavy load forever and nothing but running higher octane fuel helped. Hoping the shorter plug will change the flame front a bit. We will see!
The timing specs are there just to get you in the ball park. When I tuned engines, I would advance the timing until it spark knocked, then retard just enough for the knock to quit.
My '85 had a 300 with split exhaust manifolds, offy intake, eldelbrock 500 carb, a heated carb plate from an early '60s ford and lighter springs in the distributor. It was a great challenge, but after all that, I would have been happier if I put a 460 in it.
Sounds like you had a fun build! Yeah, I thought about doing a 5.0 or a 5.8 but I like inlines. Don't have anywhere I need to be in a hurry and I have other trucks when heavy work needs to get done.
Yup! Messed around with timing a bunch. Put it all the way down to 0° ran poorly and still knocked. Runs the best at 8°, spec is 10°.
