Our street stock (dirt) class has opened up the engine rules for us next year. The rules state that the engine must have a cast block, cast heads, aluminum intake (optional), any gas carb, and headers with 2 1/2" exhaust. Any type of camshaft is allowed.
The car is a Crown Vic frame shortened to 108" wheel base, American racing tires, racing springs and shocks, and weights 3,350 with me in it. The track is a 3/8 med. banked clay track (large swepping turns) that get's dry slick at feature time. My current rpm range is 3000-6000.
The motor I ran last year is a 351w bored and strokes to 395 c.i. (4.040 bore with 3.85 stroke). The crank is a cast Scat with stock rods. The pistons are Speed Pro forged pistons. The heads on it last year are ported D0OE castings with stock size valves.
I plan on running the Ford Motorsport N351 heads next year. I plan on running the motor to a max rpm of 6500. I am looking at Schoenfield for the headers, either 1 5/8 to 1 3/4 stepped or 1 3/4 straight tubed.
What intake, header, and camshaft would be best for this motor/car combo?
What intake to run?

-how many choices do you have for a manifold?
-What are they?
-You can't do much with skinny tires and dry slick so it should be real easy to inadvertantly actually slow down from trying to go fast.
-Where are you thinking you are going to be getting beat on the track?
-I'd think the car and suspension is about 3 times as important as anything to do with making power.
