You've certainly done your homework.

Yes, your SCR will be in the 9.5 region, but more (or equally?) importantly, your DCR will be nice and high, but not too high.

Your cranking pressures will be healthy too.

Did you work out those numbers when you chose that cam ?

I hope the head assembler checked all the specs as thoroughly as you did with the ring gaps !!

 

i did my research and when i worked with Tim for parts i listened and took his advice so i would make sure things would work well together. The shop that rebuilt the heads has its hands in a little of every kind of engine, from tractors to race engines and i told them what i needed and they understood! so i am happy that i made it this far with so much help from everyone! i still have a long way to go!

 

In a sense, your engine build is an exam,and considering your effort with research and listening, I can see your exams results will be a pass with distinction.

 

I hope so!! I got my tractor engine fully rebuilt and had it running today, so 2 engines at the same time isn't to bad! Unfortunately life doesn't give me to much free time! Hahaha

 

Now I'm a little concerned. I used a sledgauge to check the piston and it comes up .011 below 0deck. Any help would be great.

 

No reason to be concerned with 0.011 below deck.

Now fit the remaining pistons and measure their deck numbers.

Once you have all 8 numbers, remove all 8 pistons, but number them 1 to 8 for re installation later.

You can then have the decks milled to give you EXACTLY zero clearances.

Trust no one, and oversee the milling machine setup and milling !

This is actually the correct way to build an engine although right now it probably seems like a nuisance.

You fitted the rings, checked them, removed them, filed them, fitted them, checked them.

It's the same principle with the pistons and deck clearances, except that you only mill and re fit once.

Ensure that the block is cleaned thoroughly once the milling is finished.

I don't think 0.011'' or thereabouts will cause issues with push rod lengths and intake manifold fitment, but double check with Tim.

Remove the crank and cam too before milling.

OR :

Accept the deck heights, and continue to build.

The engine would run fine, and you'd pass your exam. No distinction, and you'd know you cheated. LOL

By the way, is that the new spelling for 'USA' on that gauge ?

 

I thought the new spelling was PROC.

it was a Meracle that I heard from Tim yesterday, he suggested that I just put it together and run it although the compression ratio is going to be a little bit lower in then 9 and a 1/2 to 1.

If that's the case then I will just put it together today after I get home from dropping my mom off the airport, it's a nice hour 1/2 drive 1 way to get to the airport

 

LOL, I now have a cartoon image in my head of a Chinese face with a really bad blond wig.

Your SCR will be 9.2.

If you assemble the engine the way it is, I'll be the first to stop talking to you.

Rather do it properly !

Enjoy the cruise.

 

i got it taken care of, sorry for the late reply. it got really busy.... and i just graduated on the 11th.... so it was busy! i got it almost put together... and i just got my push rods from tim. and the last thing i needed was the last thing i needed! the oil pan and oil pump is on, i have perfect valve clearance, and the rocker arms are shimmed perfect middle to middle. and the rocker arms are on and ready and the roller tappits are soaking in oil so they will be ready!

 

coming along.

 

Does anyone have advice for headers?

 

great sweep rocker pattern! If they fit the vehicle I like side exit headers, others not so much.

 

that is with only a .002 shim on the rocker arms! I'm putting this back in my 77 f250 ranger. Automatic with divorced transfer case. I guess it's a little different because the vin calls it an f260.

so I'm open to suggestions from anyone that can help!

 

 

An artist at work !

I like those roller rockers.
