Thought I'd share my progress with you guys as I build my race motor. I accidentally started assembling it this weekend (you know how it goes, you put all the motor bits in one place and it's hard to keep them apart) so here's some progress pics.
The motor specs:
- 2165cc turbo
- CB super case, 7.0 deck, 10mm head studs
- 78mm forged race crank
- 94mm forged pistons w/ total seal 2nd ring
- CB 5.7" super race rods, chevy journal
- CB 044 cnc mini wedge port heads, ls1 k-motion springs, cb forged 1.3:1 rockers
- K8 cam, 107 lc, 308 dur, .491" lift with 1.3:1 rockers
- 28mm light weight lifters
- CB straight cut gears
- 4 gear dry sump pump
- giant oil cooler w/ fan
- 3gal sump tank
- dtm shroud
- CB quick tune turbo/efi kit
- turbo tbd
nice clean work area..
That didn't last long
purty heads
When I openned the case I found some corrosion, really wasn't expecting it
When men do dishes, this is what we think of...
Got things drying out now ready for some oil
Quick test of the bearings and case, this shot was after i split it again
I didn't get any pics when I checked crank to bearing clearance, but here's a couple of putting the crank gear assembly together. The oven is your friend during this step.
Crank to cam clearance? no problem!
Put the rods on and checked clearance, but apparently those pics didn't upload. :P
Almost buttoned the case up, had case sealant on and everything, before I realized I didn't have a cam plug
That's it for now, I had to cover it all up until I picked up a couple things. I have to verify this but I might be running a distributor-less ignition, so no dizzy shaft either.
This is for Anton to show him how the lifter retainers work
Got the case halves together with sealant and torqued down.
Closer look at the raised barrel seats and you can also see the raised roof on the case
Next up, checking ring gaps. Everything looked good and only had to file a couple.
Here's a close up of a total seal 2nd ring for those that haven't seen one. The main ring has a step machined into it and theres a smaller ring that fits into that step. You position the gaps 180* from each other and it's a "gapless" ring.
While were on the subject of rings, if you're doing rings for the first time you'll notice that the 3 part oil ring has colors on it. It might be red and green or blue and green but both colors need to be seen when you put it together.
94's are big mmkay?
Time to put on the 10mm head studs, only theres 3 different lenghts. where do they go? Looking at the barrel seats, the longest studs go on the bottom row close to the oil sump. The middle length go on the top row, 2 per side, one by the fly wheel and one by the fan belt pulley. The shortest ones go in the middle in the top row. One exception to this is 73 and up cases and I think type 3 cases (though i could be wrong). They have a deep stud above #3 by the flywheel and a long stud goes in there instead.
Here you can see a normal stud on the left and deep stud on the right. Also You can see the case savers installed.
Now to put the cylinders on... or not. This is as far down as they go. Not something you would normally run into but since I'm building this with 94s, 10mm studs and case savers the head stud registers in the barrels need to be clearanced. A little quality time with the dremel and they fit.
Thats better!
With that headache out of the way now I can check crank end play and install the rear main seal.
13lb lightened fly wheel, and the end play tool installed
good endplay numbers with 3 shims
Pulled the fly wheel back off (what a pain) put the o-ring in the flywheel and the rear main seal in the case (thanks for the tool Anton)
Now here's a tip, if you get the fancy chromoly racing gland nut remember it's a 1 1/2" bolt and you can't use the torquemeister on it
Got the pistons and cylinders on to check deck height. Make sure pistons are installed right side up (arrows pointing to the flywheel). In order to use the deck height tool correctly it's gotta be torqued down to head torque specs, 26 ft/lbs
Looks pretty good across the board, .069" +/- .001 not too shabby.
Before I quit for the night I had to toss on the dry sump pump to see how it looks and make sure everything clears.
