Brian,

Don't have any experience with either but if I had to choose would select the 360.

I like the 360, larger venturi and throttle bore.
Works very well on the 90 series engines, may be a bit small for a 101 but it should work oK.
I have used these on many of my engines and the HL360 is very capable of running 50% alky without modifications, that is a bonus.

The 334 might be better for a real tight course with the smaller venturi.

My thoughts,
Scott

I might add that I installed a double pump stack on the one I used for half methanol. Not sure if I really needed it but I figured it added a little latitude to the set up.

The 360 is an advantage however what you should really find is an HR for a 91 or 101. While on the subject I'll just mention that a 360 is not legal in the Sportsman classes or classes that call for a 1" throttle bore.
