Title: which exhaust clears an Autocraft stage-and-a-half oil pump? Post by: Jonny Grigg on April 23, 2010, 22:08:41 pm hmmmm.....
Got another little problem to deal with in building this 2442 race engine. ::) Offered up the JayCee 2" exhaust this evening and it clashes with the Autocraft oil pump. Big time. I presume these pumps have been used with merged headers since time began, so I doubt I am encountering something new here. So the question is, which exhaust clears the Autocraft pump? Any hints would be helpful- either 2" or 1 7/8" fully merged race header preferably stainless and good quality. Who sells 'em? Title: Re: which exhaust clears an Autocraft stage-and-a-half oil pump?

I also polished off the two lower corners. It fit and it was close. After a few big wheelies that smacked my header into the track, it clearanced itself
