Lookin to choose an intake for a 406. Here are the particulars:

3000lb Street Stock
12:1 comp 406 with 5.7 rods
2.06/1.60 valves in 215 Dart Iron Eagle heads
Single plane is allowed
P/G with a coupler (no torque converter)

I don't have the cam card with me, I can add that info later. The track is a 1/4 mile egg shape with a fairly tight 1+2 and large 3+4, so I'm estimating my rpm range between 3500 to 6500 (its a new car with a 6.20 gear so I'm doing a lot of guessing right now). The engine builder tells me that 6500rpm will be the peak horsepower. I used a single plane Edelbrock last year, but its about 25 years old and I thought there might be some advancements in design in the last quarter century.

Any suggestions? Need more Info?

Thanks in advance,
Western Auto

I'd use the 2925 Super Victor . With the extended plenum design , it will help a lot with low end torque . Running on 1/4 mile track in that heavy of a car , low end torque will be what your after .

You need the HyTech Torklink. It produces more torque than anything else, 6" high, divided, cut down plenum, dimpled thruout, its a work of art. There are in SLC Utah for about $300 buckaroos.

We run a 406 almost like to yours except we use a worked over set of double hump heads. we run on a 3/8 mile and have had good success with a victor jr. I beleive the car scaled at about 3200 with driver.
