Head Gaskets???

-
will we do some calculations on the compression ratio tomorrow...like a best to worst case.......

we got new springs and valve seals to put on the heads.....

I think right now...it would weeks to get anything done in a machine shop....i think he wants this running soon....

No thanks to the machine shop and milling anything. That's for when this guy has a spare 340 block :)

The only thing I come back to is cam choice still, esp with knowing now that the block is 30 over. I over think this stuff to much.

Ps I'm now loaded up on liquid gold...aka brake cleaner
 
WE?......lol

Yea I cant have you helping me without me helping you. Plus I'm going to make sure you get to drive that beauty around sooner rather than later. The race cars can wait, and trust me I'm a persistent ******. :)
 
Docs a sharp cookie. All of us didn't know what milling the heads was at one time. A little info points him in the right direction and he can reasearch from there.

I'm glad doc is here he inspires me to get off my butt and work on my car.

Tha is for the vote of confidence. I understand the shaving the block/heads/intake down for clean flat mating surfaces and blue printing. But sometimes it can be stated in ways I second guess what someone is actually talking about. Or if they are talking about honing/porting. I'll catch onto the li go better as I go.

Also dont get off your butt and work on your car. My back hurts and so do my fingers. Also I've been told it's an expensive bottomless rabbit hole and you find more things "that need done."

Also FABO likes to spend your money :poke::D

Oregon Cam Grinders has their version of the 68 340 cam. That's one you might think about. @krazykuda Karl can tell you about it. He had a hand in getting them to offer it. Nice, reliable, slow ramps so you can have trouble free operation everyday.
 
is that cam card the old one or a new one?
cc the heads and figure the true compression
NO SCHOTCHBRIGHT
and agree on not using the mr gasket on that deck

That's the new one.

The old one is the norris camshaft 270H specs -

Yes, I have a custom ground cam that I bought off another FABO member a long time ago... The guy had both 340 grinds done by the grinder, the stock 340 auto cam and the 68 340 4 speed cam...

Another member contacted me a few years later and asked if he could have it sent to Oregon Cams so they could measure and copy it... It turned out to be close, one lobe was about 4° off and the exhaust lift was .006" less than the book spec... Ken Hoard from Oregon Cams can bump the lobe to be right on the book spec, but he can't add the .006" extra lift to the exhaust lobe, but that won't make that much difference...

I'm not sure what the other FABO member ordered from Oregon Cams, but I believe he had the lobe bumped back to the book spec... Oregon cams can make one to the book spec, just .006" less exhaust lift...
 
nope 0.45 is the max you can go without having to mill the intake any more than you would have too


Yes, but if you mill the block and run a thinner head gasket, then you will have to hget the intake milled...

I ave a 318 that I'm putting together with closed chamber heads where I put the thinner fel pro .040" gaskets on and the intake would not fit - I galled the intake bolts trying to bolt it down... I had to get the intake milled for it to fit with the .040" gaskets...

KRAZYKUDA,
sounds like your machine shop screwed something up, i have a 1989 318 heads milled .045 using fel pro 1008 9:8:1 CR no issues, and also have a 360 with heads milled .045 1008 fel pros no issues there too.

I'm running the 67 273 920 head with the fel pro 8553PT head gasket...

My head guy wouldn't mill any extra off the heads but what was needed to make the surface flat and straight...

That combo will get my stock 72 short block up to 8.5 compression....
 
I've never had anything but good luck with felpro blue head gaskets in the half a dozen times I've had heads of. Speaking as a novice, they'd be my choice too.
 
I totally agree!

Yeah, Tony's the man. He'll get you hooked up. Really no need for any of our input honestly. I am glad you have him locally. I'm jealous I caint be there with yall.

I am definitely blessed he has been coming by and steering me in the proper direction.

Something is out of whack with your parts.

Maybe a stack up of factory tolerances, I do know for a fact I have an un-touched 78 318 and changed to to a LD4B intake and with the standard blue fel-pro intake gaskets the bolts were a bear to get in.
With the shim intake gaskets the bolts would slide right in.
No machine work on the engine, bought the truck of the original owner, the engine had so much grease on it from leaky valve covers, when I pressure washed it the core plugs started leaking antifreeeze.

Engine #2 74 318 I tore down, J heads milled around .010" for flatness the 1008 head gaskets and standard intake gaskets the bolts went right in on a Victor 340 manifold.

I had 360 heads on it and an ld340, but the compression was down to9 7.5 with that combo, however there were no issues with the intake fit... It has to be something in the 920 heads or the ld4b intake that I have on the "new" combo... I'm working on it...
