So the 330 and the 3450 are both 54cc saws with open port
transfers. What I want to know is, are the transfers indentical
in their design. I know that the 3450's have quad open port
transfers that go straight up. Does the 330 have the same
design? I also know that the 3750's have quad open port
transfers that are curved.
So I was just wandering if there was any difference in the
ports of a 330 and a 3450.

I cant remember which type 3 or not but those 3450 was 60cc.
I cant remember on the 330 topends been to long since I have had
others torn down.

I have had the 3450 54cc engines apart and I have had the 3750
60cc engines apart but I have never had a 330 apart that is what
I was wandering about. What makes a 3450 and a 330 different
from each other other than the color. It could be in the way
the transfers are designed.

I've had a 330 all the way apart and split open.
Sorry I just cant remember back then what the transfers looked
like and I lost all my pics when racesaws site went down the
first time back then.
Thought, try looking at part number on 3450 54cc cylinder and
piston. Might be the same as 330.

That was a good thought.
I looked up the part numbers for the 3450 and 330.
The 3450 54cc has a different part number for the cylinder and
the piston from the 330.
The piston ring has the same part numbers for both engines.
So the 3450 and 330 are not identical saws and there is some
difference going on. Until I open one up I guess I will not
know what specific item is different.

That is exactly what I suspected. The 330 is large dual port
transfers and the 3450 is quad port. Thanks for the pictures.
Now which is the stronger running engine and we will know which
transfer design was more effective.
I am almost sure that the 3450 is the quad port transfer by the
way.

single in double pic.
Tried to brighten up so you can see the quads on 330. pic blow.
