Building Zoomies

(1/4) > >>

fordpinto1972:
Going to build a set of zoomies for my small block ford. Bought the flanges with the 1 3/4 stubs and going to use 1 3/4, 90 degree pipe. The first leg is 3 1/2 inches and the second leg is 16 inches. Trying to figure out the lay back angle of the pipes. Does 50 degree sound right? I've been running door cars for years and this is my first FED. I've waited almost 50 years for this. I know most of you run Chevy power plants but I have this 540hp small block ford I'm going to play with. Thanks for any advise, Don

Its all in what you like. 50* is strong. I have built quite a few sets and most where in 30* area. I have done 2 sets at 40 and one at  50 looks cool IMO.Does put more exhaust back towards driver. Not normally big deal,just thought

We just aim the pipes at the top of slicks, 2 1/8 dia

heres a set i did awhile back, customer wanted 2" tubes but wanted the typical 1-3/4 flange,  has about 2" of stub then 6" of tube after the bend, these have a 6" clr bend 45* lay back.

BK:
Make sure to lean them out enough so you don't need to remove them to adjust the valves.
I was just talking to someone with that problem over the weekend.
