for the record... no one replied so i just went ahead and got the 14.2:1... hopefully this isnt a massive mistake.

ahhhh, it might be...... :?

a LOT depends on what variables Wideco used when calculating the compression ratio. I know for a fact that they, and other piston makers screwed up 4AGE ...

did you sell the 5 speed conversion parts??

what kind of flowbench did you use? @ how many inches of water was it measured?

This head has a potential client... in an AW11 from Cally.... waiting on his shop to get the block finished.... before he pulls the trigger......


been a while but OST-039 now has an owner... chamber volumes are equalized, depth of cut will determine final chamber volumes

I was told to shaved the block at 40 and the head at 40 as well and to leave the cylinders stock that way the engine won`t
over heat! and to get a set of double springs.. does it sound right to you?

40, and 40 is .080", or over 2mm. Just cutting, without knowing isn't the best way to build an ...

ASSUMPTION: 310 cam is 310 degrees duration? Not knowing the 3T as well as I know the 4A... it is likely you will need a few thousand dollars worth of supporting parts, and machine work to properly run a 310 duration cam.

If you are prepared for that kind of expense, I'd say new pistons at the ...

Dude,


It will be interesting to see the before and after flow-rate comparisons.

.



and the results.... (before)

exhaust:
.050" - 29.8 cfm
.100" - 62.4
.150" - 95.8
.200" - 112.2
.250" - 118.3
.300" - 121.3
.350" - 121.8


Intake:
.050" - 39.4
.100" - 79.8
.150" - 118.8
.200" - 150.2
.250 ...

and a bit more detail.....








flow results to follow........


more to come.......

4 angle valve job work ?

can't be sure if I see what you are seeing, but what appears as a 4th angle is the throat of the seat, that will be blended into the surrounding bowl
