first i want to say hello just joined here a few min ago Grin the car that iam working on is a 67 gtx (clone) street and strip set up iam needing to find out if what iam thinking of doing will work out before i invest in parts and make a error Frown  the hood that i have on it now is a afx scoop iam wanting to run a victor single plane intake with a 3 inch air cleaner  i know from past experience i was able to run a mopar m1 single plane same air cleaner  under my stock hood of my last ride a 67 coronet R/T so hoping anybody that has been there done that please let me know pics would be even better Laugh  once again i want to just to say hello to everyone here  Smile

well after looking around i found the simular set up on a 63 savoy with a max wedge scoop which is not as tall as the afx scoop that i have so its looking like its gonna work out now the only thing left to figure out is my combo is a 440 with a 509 cam stock iron heads with port work headers are 1-7/8ths 3500 stall manual valve body 4.10's out back they say that the victor rpm range is 3500-6500 how will this work with my set up not sure of the 509 rpm range ive heard it dont start pulling till 3,000 which if this is true it may work out ok but just trying to get as much advise on this before buying the wrong stuff

The Victor manifold will work for your engines application. It is perhaps more manifold than you would need. The 509 will work in the range of 3000-6000 rpm. The intake manifold is rated 3500-7500 rpm.

The limiting factor would be your heads, as generally, ported factory iron heads will flow in the 255-260 cfm range at .500", UNLESS the head porter is very good. This will limit your maximum power to about the 5400 rpm range. It will continue pull beyond 5400 rpm, but the peak would be around 5200-5400. The Victor will allow you to get everything the head is capable of at that rpm but you MIGHT sacrifice some lower rpm torque. It just seems like more manifold than you need right now, but it will allow you to build bigger in the future.

i was thinking of getting a pair of aftermarket heads later on to help with this combo go beyond 5400 rpm maybe even play with some nos fogger direct port injection system staying around a 150 shot would the nos help with the tourqe and mid range power? what heads should i go for staying within $2,000 mark

For your package I think the M1 single plane will probably work better. I think you'll have a better usable torque curve especially using the 509 cam.Dave

If you want to enjoy your ride on the street you don't want a single plane intake manifold. A single plane intake is intended for high RPM use. Also where and all out race engine has no sweet spot.
  The dual plane intake manifold is the way to go for the street. It makes torque at lower RPM. The driveability is so much better. There are really good dual plane intakes Edelbrock,Victor series are great. Good luck.
