    intake.jpg Is this a #360? Will it flow remotely close to a performer rpm? I kinda like the look but don't want to put a dog on my motor.

  2. the carb will be the dog in this fight, not the intake.
    Matching the carb to your driving will be the key to its performance. Of course if you are running a race cam then it is not the intake to use.

    Iron heads-2.02 intake, 1.60 exh, flat top pistons comp 280 magnum cam. 600 Holley vac. sec.
    I also came across a vintage Torker intake cheap. Its going in a very light 36 Austin and I plan on up-ing the rear gear and some more stall if I go with the Torker and maybe use a 600 double pumper. I want the look of an early intake with the oil fill tube.

    Id use the Torker over this. These intakes are great for building low end torque in heavy cars. That Austin will **** n get with the torker.

    From the pic it "looks" like it isnt the high rise 360. If it is, than this ones fine.

    Thanks for the reply, I'm trying keep costs low and use what I have laying around. The Offenhouser can be had pretty cheap but I couldn't find much info on it. The Torker was my original choice and its sitting on the shelf.

    Looks like a 360 Equa-Flow unless the head ports have horizontal dividers, then it's a Dual port 360. I've included the catalog page for the Equa-Flow and the RPM range chart. offy.jpg offy2.jpg

    Ya know, almost any machinist can do the oil fill hole for you on the Performer RPM, right? Why not use something that is more matched to what your engine specs are, rather than trying to make old stuff work? I mean, I understand the spirit of what you are trying to do, but you have spent for some good, modern internals and all. SAM_4312.JPG

    New intake with the oil fill drilled, grind off all the names and markings throw some fake patina on it - heat the intake in an oven to about 250-30 degrees make some nice oil and gas stains on it, It will fit right in.

    I don't know that I'd patina stuff, but on the one above I ground all the names and marks off, then went back over the area with a scaling head, sandblasted then bead blasted the whole deal, then set up a hidden PCV behind the carb. You couldn't tell what it was unless you really knew manifolds, and it worked out great.

    I thought about the fill tube in the RPM and your right its probably the best way to go. I just can't seem to stay away from old after market stuff. I get ribbed all the time at swap meets, "Ok lets see what old useless **** Phil bought this time". The chart above is very cool and I will add it to my folder. I did the PCV hide on my FE motor. Used the draft tube hole and the oil filler top was my breather, that way no holes in the valve covers. I even used an old gl*** fuel filter bowl to catch any oil or condensation. I will try the Torker and see how it goes and probably buy the Offy to take the Torkers place on the shelf.:D
