Holley #5029 - what size is this? On Ford 460. Bad performance. What size do you suggest?

Holleys are hard to keep adjusted. Get a 650 Edelbrock carb.

If the engine is stock and it has stock heads and cam, use a 650cfm carb. If the engine has high performance heads and cam, use a 700-750cfm carb.Barry Grant makes the Race Demon carb ranging in size from 650-850cfm.It offers outstanding performance and its easy to tune. If you're planning on it being a race only vehicle and it has high performance heads and cam, install a 750-800cfm carb

  • Bad fuel pump or bad Mass Airflow sensor? My truck us having very hard time starting up. It cranks over, putters and shakes really bad then dies. Once it finally becomes drivable, it almost stalls when accelerating from a stop or turning right Could this be a bad fuel pump, bad MAF, or another failing part? Truck is a 2006 ford ranger
  • Aren't you amazed by the capabilities and the size of today's full-size pickup trucks? I drive a 2011 Ford Ranger XLT 4x2 with a 4.0 liter V6 (~245 ci.) engine. I was looking up the specs for early-mid 1960s F100s (considered full-size), and they have nearly the same GVWR, towing capacity, payload, horsepower, wheelbase, and height as my "compact" truck. In your opinion, do you think today's full-size trucks are amazing or too fancy/over-sized (a traditionalist like me)? P.S.: I like all American vehicles
  • Will high performance spark plugs have any benefit in a non performance car? To start I have a 2002 Ford Focus ZTS with 150000 miles on it. It needs new spark-plugs, and the only two types the store has that fit my car are Autolite Platinum and Bosch Platinum IR Fusion. My question is for my car, is there any advantage to spending the extra 14$ to get the higher end spark plugs or would it just be a waste of cash?
