I am looking at buying a 327 out of a 1965 960 3-ton truck. I am told it's 4 bolt mains. Is this possible? Also, would it be steel or cast crank? HP? Any other info about this motor would be appreciated.
Thanks

None of the 327s were 4-bolt. If you see one it's a hybrid.
350 was 4 bolt mains out of the trucksQuote:

there is no stock 327 4 bolt mains, to get one people would go to a machine shop and have one drilled
Hey Southern Gent,

There were very few 4-bolt 327's....I have one I personally pulled fron a 69 1-ton truck.....lg jrn crank
most of them were steel.....3/4 ton and up came with a steel shaft...
What are the block casting numbers?In all the information I have I can't find this.Are you sure?Maybe you are talking about a 427 tall deck big block chevy.Quote:

There were no 4-bolt mains on small journal 327 blocks, but the large journal 327's could have had 4-bolt mains because they are essentially a 350 block.
I would really like to know what block casting numbers these 4-bolt 327 blocks would have.Quote:

did anyone check out the early 327 4 bolt blocks that came in the vettes and i think that they were 375 hp
Those blocks did not have four bolt mains unless someone had the block machine for four bolt main caps. 327's with small journal cranks did not have four bolt mains from the factory. I know because I had one.
In 1965, my buddy and I bought a brand new 375 hp 327 short block from the Chev dealer. It did not have 4 bold mains. As I remember, it cost just over $300!!

I have had several of the Vette 327 blocks-None were four bolt main.
This is interesting, I have never heard of one either. I just checked Mortec.com, every 327 casting number there of any year is 2 bolt block.
I worked in Chevrolet parts in '67-'69. As I recall, I think there were some large journal crank 327s, but no 4-bolt blocks. Warning: My memory has failed on rare occasions! :-)
We sold a lot of 375 HP 3/4 motors to the local Illinois dirt trackers. They would add a roller, port injectors, and a mag, then drop them into sprint cars. They were 2-bolt blocks.
well the 67-68 dz-302's were lrg journal 4 bolt main 327's with 283 cranks <basically> then in 69 they got there own 302 block the DZ block the 67-68 blocks have MO on them.
Could the 327 be an industrial 327?
I recently acquired a motor to put in my 85 C10. I was told its a 327 which I was very excited about. I also noticed it was a 4 bolt main and didnt think anything of it. Since then I have looked at mortec.com and found that there are no 4 bolt main 327s listed. however the site that someone mentioned earlier has them mentioned. I am going to get the numbers off the motor and find out for sure what motor it is.... Do all 327s have a recessed oil filter or was it just the 65-67 Chevy II/Novas?
Do the number check and get back. By the time you do your research start with the numbers' you'll have a better idea of what you have from the factory. 4 inch bore blocks can have crank, rod, and piston combos for different displacements built by a hobbiest or engine builder.
FYI - I've found that the 2 letter suffix is the easiest way to begin IDing a block.
Here is a list, if you look past the ebay ads at the top of this page -

Which number is the number you need to go by? Its really really hard to make out the numbers on the flat piece infront of the cylinder head because the partial vin that is supposed to be below it is stamped directly on top of it. I tried to make it out but im not sure i was correct because when I looked that number up it came back that it was a 327 out of a chevelle. Then I looked at the number on the back of the motor and checked that one and it came back that its a 350 out of a truck.....
hi, all if i remember right, they made some of the 4 bolt mains in the earlier vetts, i think that they were around the early 60's. the spec's were 327/375 hp/fuelie motors ? ckeck the numbers and good luck
In 1969 the 327 was just a 2 barrel engine.Quote:

You will see some castings that were 2 or 4 bolt mains. I think in 69 the 350 and 327 used the same block casting.
I know some Vettes and medium duty trucks still had a small jornal crank in 68, GM must have been useing up late 67 parts in some early 68 productions.

Nope. All the 60's vettes had 2 bolt 327's.Quote:
