I'm building a 300... 5/19/12 SHE'S ALIVE!!!

No they did a valve job too. Do you sense something shady?

[woods]

No, nothing "off". They probably just sprayed the dye in there to cut the seats. Normally speaking, when using a die to check for cracks, it's on an aluminum parts. The dye penetrates any cracks, then wipe it off and spray with a white so it shows up.

EDIT: Typed a reply but got up in the middle for something and woods had already responded. I worked as a Pipefitter for about 10 years and have seen 100s of penetrant test done and it didnt look right to me, but spraying for surfacing would cover it.

[woods]

Yep.

[fomocoguy]

Ok, I bet they cut the valves and seats, then sprayed the die before milling. That's why no die on the valves.

Got my hot plate mostly fabbed up today. I still need to go get a big drill bit and 1/2" pipe tap for the hose barbs.

And here's my experimental aluminum cylinder head

[woods]

Put a brick on that head so it doesn't float off.

[killakobra]

i'd give that experimental aluminum back, it's rusting!

[woods]

That's the experiment.

Hey woods, on my head gasket the feller asked me what size bore I want. My bore is 4.030, but when using copper is the hole usually a little larger just to be on the safe side, like .010 bigger or something in that range?

[woods]

10 bigger would be just fine. As long as you don't have any gasket hanging over the bore and don't have it so big that it makes a little shelf dead spot between the head and block for mixture to "hide" in.

[fomocoguy]

Just got a call from Mordy at gasket works. They'll be cutting my head gasket today and shipping on monday. It will be in .022 copper with a 4.040 bore and annealed for me. This will put my quench between .036 and .046 on all cylinders (varying due to casting differences in the stock replacement pistons ) Finally feel like some progress is being made!

[woods]

Is it all in the pistons or a combo of rod length and such?

[fomocoguy]

Well, since I measured the quench after it was all assembled I really don't know. The crank was ground and new pistons were installed on the existing rods, so it's probably a mix of everything. I should hope that the crank was ground correctly!

Not a lot getting done today. Mom's working all weekend so it's just me and the 2 year old who decided nap time only needed to last 30 minutes. I had time to clean and organize my work area and cut a few gaskets out, but that's about it.

[gregamorton]

any updates? I got me a 240 and a 3speed rug with overdrive. Kinda thinking of putting it in my crewcab to play with. I think it would pull it with 4.10s!
