I am using a streetmaster and 3310 vac secondary holley on my 390. I have room for a carb spacer in my car. I am wondering if the stock 352 aluminum carb spacer with the heater hose routed through it would be good to use. Here in N FL it gets cold enough to make a holley ice up--I had lots of trouble with this in the past--this would likely solve that problem, but would the steady heat under the carb cost me power during the summer?
Maybe the steady temperature would help keep the carb in it's optimal tune through a wide range of ambient temps...thoughts?
