305 Canadian block ?
 

I am curious why people occasionally advertise 305 Canadian block. What is it about these blocks that makes them more desirable ? Thicker casting or ? Thanks.

Tim…I have 1/2 a dozen Western Canadian 305 Blocks that typically might be worth even more because of their Geographical Correctness. Hopefully we find out Why? MB.

Re: 305 Canadian block ?
 

From what I'm told is that some Canadian 305 blocks had 4 bolt mains more so much in a heavy duty truck application.

Re: 305 Canadian block ?
 

From what I have been told was that the 305 4-bolt main blocks were a special order from Iraq or Iran or something to use in the Chevy Malibu that they imported for taxi use. Came with a 3 speed standard trans and a/c.!!

Re: 305 Canadian block ?
 

I have never seen an Irakii Taxi (not trying to be politacally incorrect but that's what they got dubbed with) with a 305. I've only ever seen them with a wee six 3 speed stick and dog dish hubcaps, bench seat and rubber floor. Pretty homely lookin jalopies too I might say.

Re: 305 Canadian block ?
 

There were 3 versions of the Iraquabu. ( I sold 114 of them). The base
models were 4 dr. 3 speed manual transmission, these were destined
for the soldiers. The next level were 4 dr. Automatic trans. These were
for the Sargeants. The top levels were the station wagons with
auto. trans. These were for the Generals. There were 9886 of them
on the docks in Halifax, and GM never got paid for them, so they
tried one wave of them on willing Dealers. We sold out in 3 days.
Never saw the cars at that point, took deposits in person or on the
phone with no gaurantee of color choice.The colors were light blue,
a weak gold color, a weaker yellow, and a nice metallic red. All the
ones we got were 305's with A/C. They were 1981's and were sold
in 1982. Prices on wave 1 were 5995, 6195 A.T. 6495 SW AT. On the second wave GM charged us 200.00 more so the prices went up 200.00. J.R.

There use to be an IraqiTaxi here in my hometown. It was a 305ci w/ 3 speed stick as I recall. I have never seen a factory 305 with 4 bolt main, in my nearly 40 years of messing around with Chebbies ? This is an interesting topic as locally we treated 305's like the plague and got rid of them as fast as we could back in the '80's.

Re: 305 Canadian block ?
 

yet another racer (Bill Bogues) listing his car for sale with 305 Canadian block ... must be stronger just like our beer ?

Re: 305 Canadian block ?
 

Canadian Blue Light is stronger than most 305 blocks...

Re: 305 Canadian block ?
 

There is one for sale in Ebay:

Re: 305 Canadian block ?
 

I find the ebay ad an odd listing.

"Block is bored, honed, decked, finished, ready to go, just needs main caps!"

Re: 305 Canadian block ?
 

Yea, Joe and Larry just where is that block ready to go.
Maybe back to a shop for some main caps or to the scrap heap??
Add:
After looking & looking at that picture on E-bay I think the picture is a 350 block

Re: 305 Canadian block ?
 

Just clean up the three center main caps you have laying about and bolt it together, no problemo.

And at $150.00 a fantastic bargain. Makes it mighty handy not having to check anything.

Re: 305 Canadian block ?
 

But can anyone on here absolutely confirm that Chevy sold 305 4 bolt main blocks in passenger cars or trucks ... Have yet to see one.

Re: 305 Canadian block ?
 

The 305 Canadian block I have in Sharons car has a thicker main webbing than the other two bolt blocks that I have seen. Also the block is about .20 to .30 thicker in the cylinder areas that other blocks. All the GM guys I used to work with that poured them said they were made thicker due to the colder conditions up north. This also applied to the 350 blocks too. Most of them that I checked always had one or so cylinders out of whack that had some core shift, but they were all thicker than a reg block.

Re: 305 Canadian block ?
 

Not to go off topic but there was a thread back in 2007 about using a sleeved 350 block for a 305. Does anyone have any updates on whether you can run a 4 bolt main 350 block thats sleeved? Chances are I'll just fill my 305, just curious though.

Re: 305 Canadian block ?
 

I don't know about those Canadian blocks. They might sound funny,eh ?

I went to buy a flooded generator at a business, that a natural gas 5.0 GM engine, because they supposedly were 4 bolt blocks. It was gone by time I got there, so I didn't get to find out if it was true or not.

Re: 305 Canadian block ?
 

Hey KWIG....
To the best of my knowledge those blocks you speak of are the same as the other 305 's except they came with a bottle of Crown Royal and were bathed in maple syrup...to prevent rusting
But not many survived it into race applications because they came encased in a huge block of ice shaped like an igloo
I 'll check with my operatives in the Royal Canadian mounted police to verify!!;)

Re: 305 Canadian block ?
 

Greg, you're right we kept it a secret until you've just let the cat out of the bag.Ok, here we go, all 305 truck engine in 3/4 ton and 1 ton 4x4 application had the four bolts main, all 1/2 ton had the automotive 2 bolt main but due to sometimes delivery problem from the foundry the auto version was install in 3/4 and 1 ton.This confirmation from my neighbor who was a GM tech in charge of formation for their technicians.U.S. Canada and Mexico.cr

Re: 305 Canadian block ?
 

Sorry Mr. Cicero....guess I had too much Tim Horton's coffee this morning, watching the beavers and moose meandering about the forest on my way to the outhouse
Can you still buy those secretive 305's with a few loonies and 2 nies @ Canadian Tire???:D

Re: 305 Canadian block ?
 

Mostly with Canadian Tire money which is doing better than our Canadian dollar.lol

Re: 305 Canadian block ?
 

must be really rare

Re: 305 Canadian block ?
 

Pretty sure 3/4 1 ton trucks were 350 400 ,454 during the years of 305 production. ...Trevor

Re: 305 Canadian block ?
 

I have a Chev 3/4 ton with a 305, made in Canada. Used to tow my open trailer and stock elim car with it.

Re: 305 Canadian block ?
 

I also had a 3/4 ton Chev Van with 305 4 bolts main, I gave it to my brother who ended rebuilding it and got another 350 km. I pilled my race cars with an open trailer with no problems. Great engine, it never gotten the respect it deserve. CR
