My Engine Build. Big Block content.

[ProStreet68SB]

Picked up a 454 big block last august. Had a wiped cam and I knew it was in need of a full rebuild.
Here it is the day I picked it up.


Within 2 days I had it in class and fully torn down.
Balancer was on tight enough that I broke 2 pullers before getting it off.
When I received it, it had a 10qt oil pan on it as well. Along with full ARP hardware for the timing chain cover and oil pan.


Inside was a Scat 9000 series crank, Scat forged pro-comp i-beams, and KB hypers.

Pistons and rods finally out.


The cam and lifters were wiped as well. They took out all the bearings.

And down to a bare block. Which is how it stayed up until last week. *july 2012*

Brought it back and was finally able to get out what plugs were still left in it.

For cleaning I had two options. I could either shot peen or bake the block. I choose to bake the block. Baking takes the block to 500 degrees for about 40 minutes
Before

After

Turns most of the dirt/carbon/paint to ash.

Finally clean after a run through the jet washer.

Wet-magged it today as well and everything looks good.

Got some work done with what little shop time I had today. Installed main studs and checked to see if I had to align hone. Spec is 2.937-2.938 and I'm right at 2.9375 so I won't have to be doing any align honing. I chose 1/2in. ARP studs with provisions for a windage tray.

Studs installed and waiting for the caps.


TQed to spec with the caps installed.

Got a decent bit of machining done on the block today. I square decked it. One deck was at 9.798" and the other was at 9.796", essentially the stock 9.8" deck height. Zero deck for new set up is 9.780. I ended up right at 9.7785 on both decks after machining. and I'm okay with that, as I'm already a little low compared to the compression I'd like to have.

Squaring fixture set up in the block. Theres a 90degree plate on the other side that we level off of to assure a square deck.


It then got setup in the machine and decked.


After all is said and done.

Took the pistons out today. All measure right at 4.2776". Meaning I wanted a final bore of 4.282. I chose to make it a a little on the loose side as I plan on spraying some nitrous with this build.

Forged SRP Pistons. 18cc dome will create a 10.2:1 CR with my 119cc heads. Uses 1/16, 1/16, 3/16 Rings.



Instead of the traditional bore and hone. We decided to hone it over. We have diamond stones in our hones and create less/zero taper as compared to a true bore/hone, as the hone is almost fully computer controlled.

[ProStreet68SB]

Got to finish taking all my cylinders over today. After finishing, I went ahead and plateau honed each cylinder. This knocks down the peaks that even diamond honing leaves behind, thus aiding in ring sealing even more.

All finished with machining!


Also took some time to grind of casting flash.

Well today was the last day of class I had to do work. But I managed to get a little work done.
Since the motor was stroked an 1/4" we had to check clearances. We did this by setting the crank in the journals with a single rod/piston and moving to each hole to check clearances. I had no less than 1/8" of clearance, which is surprising considering I am using H-beam rods.

Crank finally sitting in it's home.


Checking the clearances.

Not yet, I need to pick up a ring filer so I can finish my ring sets. Paint supplies will be picked up soon, plan on making this a better than average looking motor.

Wow I'd kill to have access to such nice machinery!!!!!!!!!!!

Your doing a first class build here. Your about to that point of chosing heads. whatcha gonna do there?

I have to ask,, you keep talking about 'class',, is this a build in a school / college machine shop class?? or is classes disrupting the time you uhave to work on the motor? Private shop or what?

I'm a student at the University of Northwestern Ohio, so I have access to all this here at the college.

Just bought heads for the engine. Brodix Big Brodies with 2.25/1.88 valves and 315cc runners. Freshish rebuilds with new springs and titanium keepers. Came out of Reher-Morrison's shop. Pics to come tomorrow.
