SM Needles or other type for 3 screws SU CARBS

Recommended Posts

My engine has been modified to 2.6L with oversized pistons and Schneider 274F. I guess i forgot to tell Bruce Palmer of Ztherapy this fact and at the moment of refurbishing the 3 screws roundtop su carbs he placed a pair of SM needles. Isnt it better to use another type of needle when having a modified and engine and a non stock camshaft? If so, which model?

I had Z Therapy rebuild my SU's for my 5/71 Z. They have the SM needles. I'm at 5,460ft in elevation so they are a bit rich at low rpm's, but fine otherwise. The camshaft is a DeLong that FAR Performance installed back in '72. Specs are similar to the Schneider. At that time FAR also installed SM needles.
