In light weight cars with big engines I prefer mechanical secondaries. The other good thing about this carb is it is one of the least expensive Holley carbs you can buy.

i'll have to agree with tom, i have been running this carb on a couple of different types of cars. first on my dragrace chevelle with 502/4sp combo. and now on my 427 cobra. just some re-tuning and what a great carb. instant throttle response and if you keep your foot out of it........desent milage too. i love those 9381s.
