Need cam ideas for my 318 Duster
You said
I want my Duster to be an easy mannered street toy for day trips and once a while to the strip. My goal is to run a high 7 on 1/8 mile with a car that works good as a daily driver.
Yur gonna need ~350 hp with a Superstock chassis.
With a street chassis, that will be about a second slower.
Thus you will need the equivalent of a 100shot of Nitrous on top of the 350.
My street chassis barely got into the 7s, at 93mph. By the Trapspeed and car-weight, this was about 430 hp, for 7.92 seconds and spinning all the way. That was fast enough for me, one good run and I went home.
But, I have an HO367 with alloy heads and that run was done at about 180psi. AND I used FOUR gears to get there!
But, I have 3.55s and a GVoverdrive so for me, 65=2240 rpm. This makes a fun car to drive, but that 230/237/110 cam of mine she sucks gas pretty hard. So, I retired her from DD.
As for you
Good luck getting enough cylinder pressure for that size of cam. and if you don't have the pressure, she'll be a lousy DD
I did a quick study, and and for that 235* cam, say with an Ica of just 66*, to get to 190psi will require, an Scr of 11.7
In a 318@20 over, that comes to a total chamber volume of 61.6cc With a zero deck and 5cc eyebrows and a Fell-pro 039@ 8.6cc, that means your head chambers have to be down at 48cc or less. IIRC the Edelbrocks come to you at 63cc. You see the problem?
And that is a two edged sword. If you cut the heads down, you may have to cut the eyebrows for more clearance, and the intake will have to be cut, and maybe the chinawalls.

I want a cam for my 318 and need some advice.
IMO my advice is to lower your expectations.
Those 4.88s are lousy for a DD.
Those 3.91s with 28s, are 65= 3100 at zero-slip, say
3150@ 3% slip , but, how many DD miles can you get out of 28" street slicks?
IMO, with your stated goals, yur gonna have to give something up, especially being in Sweden; unless it's like 10 minutes to work.
