Hot Rods Info Needed on 66-67 SBC (Chevy II) 283.... 3862194 Block Code

I understand there are some distinct differences with these motors......can someone please explain.
Recessed oil filter cavity.......different trans mount bolt pattern back of block?

 

bellhousing pattern is the same on ALL sbc's. The hole for the Z-bar pivot ball is in a different place, And of course the recessed filter mount.

 

Thanks falcongeorge.........
so then any Chev trans or adapter to change trans type will mount to it?

 

Also, isn't the oil pan dufferent?

 

correct, oil pan and pickup are nova items only

 

The bolt pattern on the back of the block won't be any different.

Any GM transmission or bell housing that can be bolted to a small block or Big Block Chevy can be bolted to the block mentioned.

 

I believe what you have is a '66-67 Nova block.
They were supposedly stronger in the lifter galley and in the bottom end.
Of course it has a recessed spin on oil filter also. If you have the stock oil pan a unique oil pump pickup for the front sump oil pan.
KK

 

One of the biggest differences is the Nova block is worth double what the garden variety 283 blocks are going for.

64-67

Oil pan, pump, pickup and distributor to oil pump drive shaft are specific to the Nova engines, both 283 and 327's.

 

Thanks all.
Always great help here.

 

oh, can you run a rear sump pan and regular oil pump?
appears as though you can....

 

Yes- You can. As long as the draglink isn't close like a nova=hence it's front sump. Regular pan,Oil pump, and Pick up of your choosing. Also- A stock drive shaft for the pump, and your good to go.

 

Roger that!
My 327.

 

I didn't mention the pan/pickup, because I thought you were just asking about the block, but now I notice you said "motor" in the first post. I razz guys for posting without reading the whole thread, and all I read was the title...

 

Thanks all.
And sorry for being Columbo here
But.......just one more question......
Is there something different about the front cover?

 

Not on 283's and low hp 327's, the 350 hp 327's use a special front cover to accommodate the larger (eight inch) harmonic balancer.

 

if you are using the stock pickup and pan the block is drilled for a bolt to hold the pick up tube to the block and the oil pump is different, the block is drilled by the oil filter for the z bar

 

So what I'm understanding is this engine is good for any type of build and not just Novas!

 

Yes!
KK

 

Thanks everyone!
The HAMB rocks!!!

 

And Jenkins claimed the cylinder walls were thicker than most other 283's, FWIW.

 

I had to drill my fresh 355 to attach the Nova pick up tube to the block... fun. Nova oil pumps were good only to a stroke of 3.25", my 355 has a 3.48" stroke and I had to relieve the oil pump for clearance.

 

They're worth quite a bit to someone who is restoring a Chevy II/ Nova and needs a period-correct engine.

 

Respectful of the OP's post on 283's, but thought this would be of value.
Some may never have seen what the internals of the Nova 350 hp 327's look like. When ID'n blocks, the common block is the "362", but there is a "721" early production block also, I have heard some 283's were based on this block, these numbers are the last three digits of the blocks casting numbers.
Pretty rare (and valuable) components here.
May want to expand photos to read text.

 

This is the hole that needs to be added to non-Chevy II blocks to secure the pick up tube.

 

Not news to @falcongeorge, but just to expand on the subject to those who don't know.

Many mid 60's drag racers sought out these blocks for this reason, many of those famous high revving 301's were based on the Nova blocks, because they could be safely overbored without concern of running into the water jackets which was common with the non Nova blocks.

 

Yup.

 

Pulled a 283 PG out of a 66 Nova back in the 80s, a running and driving car. Been in the garage since. Guess I need to take a look at it. Knew the filter location was different, and the pan, but didn't know about the block itself. Thanks to all for that info.

 

Well, around these parts not a lot of racers here to take advantage of this block.
I was looking for a 283 and found this one and just wondered how different it was and did not want to be trying to source "special" parts for it.......so, to me, it's just a 283 as I have no need for building it for power and/or speed.
All good info though.

 

Considering the "premium" price the Nova blocks are bringing, you could finance more rebuild components by selling the block to someone that it does matter to, and aquire a regular block for much less money.
Curious as to your build plans, do you have a car to put this engine in?

 

Yes- You have to relieve a lil off the pump to clear the crank throw. maybe if you have a pic to show where and how much you took off might help some peeps...
Nice looking bottom end of your engine- BUT- there are certain limitations with the front sump pan/pick up configuration= Not your's, the factory.... RPM, and HARD braking after such..... It's an oiling /starvation/cash draining non motorvation frustration............Found that out the hard way.....
I switched to a rear sump combo with a lil drag link massage, and all was well....But that was in a Nova.
