Holley DP or 4150

[Chetly]

What is the differnce between teh holley DP and the 4150. I want mechanical secondaries and the type of choke doesnt matter. This is a mostly strip car but will drive it on the street. Driveablity isnt an issue. What are the differences and what should i get for my combo.

GT40p's milled .030
eldebrock air gap
FTI cam
4.10's
liberty t-5

Or is there another carb that someone could recomend. Thanks a bunch.

A Holley DP is a 4150. Your pretty stock so you could do just fine with either a vacuum secondary or a DP. Either one will get you the performance you want. I ran a vacuum 750 on my AMC Javelin and ran consistent 12.8's. Id go with something in the 650 cfm rangein either a Holley or Demon. You could even get away with the Road Demon. I had one on my old combo and I ran 13.8s with only an intake exhaust and gears. They are 625 cfms. Dont let anyone on here tell you to get a 750. There is no need to get something larger than 650 because these small block fords dont need it, especially if your going to drive on the street sometimes. Let me know what else you need to know because I have way too much info on carbs to just keep it in my head, lol. Hope that helps.

i want something with mechanical secondaries. But im shooting for the 12's with my combo, with suspension and slicks, i want the best carb for my setup. You say the 650sfm DP will be good.

I agree completely. 650 dp, Holley or Demon.

what are the differences between the two. Summit sells a holley 650 DP and for 300 m,ore they sell a 650 4150. Both have the mechanical secondaries. What is the difference between them?
