Exhaust size
« on: April 13, 2011, 12:30:52 pm »
Looking for info on exhaust, I came accross a reference to an article or a post by George.
It was something called exheaust size / tuning post.
Can someone tell me how to find it?
By the way if you ever do a search for George Herrin on Google Be prepared for a flood.
He has written articles for many different scorces and been quoted by so many,
after several pages I gave up.

Building on a Tec OV490 some call it OHV175.
What size exhaust to start with and how do you get an ell that clost to the head.
It only has a couple of inches to the deck.
Thanks!
Some years ago you wrote an article for tuning post either a magazine or web site.
It was about exhausts their sizing and fabrication.
Saw a reference to it searching exhaust. An old post from 07 or 08.
