What are decent times and mph for a 4mill stock cyl. Right now I get 101 in the 1/4 but no time. We have a street thats marked off. And yes its accurate.
Obviously the port heights and width are what determines the porting but you can just tell by looking at a set like this that not much measurement was used. Just broke out the dremel and ported by eye
the right side intake port looks biger and wider and the main boost port looks slanted aswell. But oh well, I have seen shee's run with slopier porting
just use thick soder that doesnt break easily and fold it like an L shape then slip it in and try to angle it to the side of the cyl. Not on the intake or exhaust, just the side and turn the motor over. That will squish the soder and then you can mic it
