Brent,

I see lots of great advice already here.

An old and respected FE Master that I knew for years, may he rest in peace, always insisted on no more than 243-245 duration IF the motor was going to run through any kind of mufflers. He also liked a 112* separation under the same conditions.

Also, he would kick my a__ if he heard about me running a single plane manifold on the street.....just not street freindly.

I'm sure to hear objections to these trains of thought.

Good luck.
