IMHO,there are better intakes out there but for a bump over stock and a little weight saveings its a good intake

mine rocks with the eddie 600 carb and a stock cam in the 440 for now.

I also have the 78 stock spedbore intake with a 650 holley double pumper that worked good also.

i will be steping up to the eddie rpm intake with a whiplash cam and 3310/750 cfm next.
