I have the Spectre Performance air box on my 66 that seals tightly to the bottom of my hood. Works well and looks good. On hot summer days I'll remove it to get some fresh air under the hood. I bought mine on ebay and think I paid $170.00 for it. FYI, I had a Moroso air box on my A/SM big...

I had same issue on my Coronet. Fuel pressure would drop to less then 2 lbs from 6.5 lbs after a half hour of cruising in 80 degree heat. gas was basically boiling in my fuel lines on top of the motor. I ended up wrapping my fuel lines in the silver insulated wrap that is available from Summit...

I read probably 35 reviews on this carb and every review I saw the new owner was able to eliminate their low end or mid range hesitation they experienced with their other carbs (mostly Holley carbs). With most it took a lot of fine tuning, most saw good increases in dyno numbers also. Makes me...

Has anyone run this carb or other Quick Fuel double pumpers with the annular boosters on a big block? I'm considering this carb for a street-strip 383, 727, 3.73 set up. I've read great reviews on these carbs and the advantages of the annular boosters instead of the down leg boosters.
