Project Beast back on track

The milling you've done is nothing compared to what can be done to one of those. Also, the piston to valve clearance, while important to check, is a MINIMAL issue with the small cams you have. Yes, I would mill that block to get within .005 of zero deck. The closer to zero the better. On some of my 16 valve drag motors I have run the piston as much as .005 OUT of the hole. Ray.

Would I need to subtract the .015" that was milled off the head? With the piston being higher and the valves being lower, won't that matter? And what about cam lift?

[rapidray]

I don't mind the cold if the garage is heated! You would need to stack some washers over the 4 outside corner studs & install the head nuts & torque down to about 35 lbs. THEN measure the deck height. If it is still over .010 in the hole then I would just pull the block off & have it decked whatever it takes to get it to zero with the base gasket you are using. I use Suzuki gaskets on stock type street builds & the base gasket measures at .010. I put the block on with NO base gasket or rings on the pistons & then clamp it down & measure. Ideally, the piston would be .010 OUT of the hole this way & I would just go on to assembly. If not, I subtract .010 from the measurement I got & that's how much the piston is down in the hole. Then I have that amount decked off the block. It's just math & a little machining but it is HUGE in the difference in power. If you are .044 IN the hole I would do as I described & deck the block the neccessary amount. It WILL be a noticable difference in power! Ray.

Piston to head clearance has nothing to do with head milling. Piston to head clearance issues come from decking the block too much & ending up with less than zero deck height, as in the piston is OUT of the hole. You can mill the 2 valve heads over .060 of an inch before they even start to make good compression. Bruce, did you measure the deck height before you put the block on with the rings on the pistons? How much is it now? IDEALLY, you want to be at zero to get the best power. Give me a call if you have questions. Most times you can get the deck height you want by using thicker or thinner base gaskets. As in copper. It's looking good Bruce! I wish I were closer to where you live right now! Ray.

You made me look!

If you mean the side of the piston (not the domed part), I measured it to be .044" below the deck. This is without having bolted down anything. The base gasket I used was a standard one...vesrah I think. Do you think I'm OK?

Oh, and why would you want to be up here? It's COLD right now!!

Yeah, thats what I was planning on.

Any piston to head problems with that milled head? I am thinking of milling mine.

I'm going to check it tonight. I'll let you know. I doubt I'll have any problems. My head was only milled 15 thou.

Bruce make sure to get some cam shaft paste before you install the cams, Web cams sells some i think. My tuner was telling me it is real important to use some when first doing a new set of cams because it helps build a more durable surface that won't wear down.

I love how you say that like "You mean everyone doesn't have a tow hook mounted on their ceiling?"
That's great! Love it!

Works great for taking front forks off, too!

[renobruce]

The head is on! No bolts in it yet, but it's on!



Hopefully the cams on tomorrow... need to hunt my friend down to help me do the degreeing.

I did something similar. I have a come-along that I put a bungie cord on to hold the tension on the chain. Worked great!

Well, that went easier than I thought it would! I used my fingers as opposed to the ring compressor or hose clamp. No problem!

Not to insult but a little trick I've learned. Tie speaker wire or something of the like to the cam chain and after putting the 2&3 pistons up throw the chain in the tunnel to keep the crank from rotating.

The 750 gears in a 1000 spin the oil pump a bit faster. To increase the volume flowed.

That looks sweet mate!
I just went back to the start of the thread to refresh my memory, and I have a question.
Why are you using 750 oil pump gears? I thought it was the 16 valve 1100s that had oiling issues.

Edit: just read on abit some one else asked you about the gears. Just ignore me.
