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

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.

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.

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!

[fomocoguy]

Nope, no updates. The fella from gasket works says he's out of .022 material and it will be two weeks before he gets more, so I'm going to get busy cleaning and painting parts and getting everything else done that I can. My drill bits showed today so I'll be able to drill and tap my intake for the vacuum port, plus drill and tap my heat plate for the barbs.

fomocoguy, Im doing the same with my stepside, did the head & new lifters last winter. Here's a couple pics of mine:


Im using a 2v Ford Motorcraft.  Im just now fabbing my plate for the bottom of the intake, where'd you get your hose barbs?

[jzjames]

Im making my bottom plate out of a piece of alum. extrusion I picked up. Its about 1/2" thick. I made a paper pattern of the bottom of the Offenhauser intake, and sprayed the piece of alum. with paint to show where to cut, and where to drill the holes.
I had enough space for two plates in case someone needs one.

[fomocoguy]

Looks good! I got my barbs from Home Depot of all places. The plumbing dept has lots of brass fittings in NPT.

[fomocoguy]

Well, kind of an update but then a step back. Mordy at gasket works told me he was out of .022 material and it would be two weeks before he got some. I got kind of tired of waiting and decided yesterday that I was just going to go with a Fel Pro gasket and be done with it. I sent him an email canceling my order, then went out and installed the head along with the lifters, push rods, and rockers. So later I check my email and I've got one from him saying "I just got the material in yesterday!!" So of couse I'm thinking "thanks for letting me know dude ..." Anyhow he cut it and shipped it today and I plucked the head back off. It should be here next tuesday according to ups. Since the "material showed" about a week earlier than he said I'm wandering if it was a case of my email lighting a fire to get it done, but it doesn't really matter. It's on the way now.

[gregamorton]

how much of a difference will the two head gaskets make on the compression?

[woods]

It will raise his compression a little, but what he's really after is tight quench.
Joe, just taking a guess, it really sounds like a case of "oh sh!t, I had better get that done" to me.

[fomocoguy]

how much of a difference will the two head gaskets make on the compression?

I hadn't figured it both ways, but it can't be more than .1 or .2 difference. It's at 9.0:1 with the pistons I got, so it may be as high as 9.2:1. Like woods said, quench is the objective. Ideal is .040, but anything under .050 will give positive effects of cooler running, less ping, and better mpg's. With the .022 head gasket I'll be between .036 and .046 across the board.

Yeah, me too, but at least it's on the way now.

Ok, nice update. The gasket showed last week and with a liberal coating of copper coat I managed to get the top end installed. I primed the oil pump just to see oil flow out the pushrods and lube the bottom end since it's been sitting for quite awhile with nothing but assembly lube in there. Got theintake and exhaust manifolds installed yesterday, and the distributor is out to be re-curved. Pics!

Your dizzy recurve guy is shady.
Looking really good Joe.
