How to tell what kinda porting I have?

[Dick Wheels]

I know that my engine has some port work done to it but have no idea what kind or who did it. I really don't wanna pull the exhaust and stuff off it but i do have the intake off and pics of that. Can you tell just from the intake if its just a cleanup port, trail or dune/drag port?

 

She runs hard and pulls very strong from way down low till she runs outta rpm's.

All engine port jobs require clean up of the intake. Which is what your looking at. The difference is in the exhaust and transport windows which changes their relation ship to the piston just like the different lobes on a cam shaft. You really can't tell anything without measuring them.

Kinda figured as much. Atleast from those pics it looks like who ever did it knew what they were doing and didnt just "Hack" away

I have the same prob kid told me it was ported & polished.. only way I could know what it is or close to what it is would be to measure it.. Jeff told me that what they did they knew what they were doing... I wish I knew what kinda port work I had..
