I have a Mastermind 45mm 346. Doesn't seem to have reduced my pecker size at all.
Money doesn’t go as far at the pump these days, that’s for sure. Someone prolly has some numbers for you, but it would help if you could share where the ports time at right now.
You can trim off the piston skirt to get to your intake duration instead of lowering your port floor.Sorry to bring back a old thread but instead of starting a new one i thought id ask here. It seems as my stock intake numbers are so far from the commonly ported intake numbers that most are using, its about 11 degrees from where i need to be. It seems a long way to grind and im a little concerned if something is wrong or if i should just "grind away". My numbers are as follows
Intake=67deg
Exh =106deg
Trans =120deg
Id be shooting for around 77Deg of intake timing but like i said, its a way off..is there differences with the OE version and the NE versions intake timing numbers?
Double check that you get the same number on both sides of bottom or top dead center. And make sure it’s actually 67, not reading 73 or 77Sorry to bring back a old thread but instead of starting a new one i thought id ask here.

I don't usually change the intake, but I do like the Walbro 198 or 199 in place of the Zama. The air filter parts from the 357 or 359 are a nice upgrade too.i might keep an eye out on the classifieds for the larger intake if it comes up for sure
