Intake and carb
I am looking for input for the best combination of intake and carb for a 390,
it is in a 68 F500 dump truck.
only looking for torque.
don't care about mileage, anything over 5 mpg is great.
don't need top end rpm
engine is a crate motor, supposed to be "street performance"
maybe 20,000 miles on it
the truck weighs 10,000 empty and is licensed for 24,000

im running a edelbrock 4 barrel 600 w/ manual choke and i'm quite pleased with it. never had a holley though so i cant comment on that. theres some websites out there that you can use to calculate your optimum cfm. heres one: Calculate Required CFM Of Carburetor according to this i should only have a 500 cfm maximum case scenario. a friend of mine had a dual demon setup on his 76 stingray. it was something crazy like 1200 cfm, i cant remember, but it was way too much carb for that car. it had plenty of *****, but not as "responsive" as it shouldve been in my opinion. and he got like 8 mpg on the highway. lol. not the best analogy on a ford trucks forum but hey im not ashamed to say at one point chevy made some really phenominal cars, but their trucks suck. ford trucks reign supreme without a doubt and stomp chevy trucks. but i do love their cars.
