Hey people just want to know some stuff about the engine build i'm doing? Firstly i'm new here, i'm from the UK and into my US GM's, as the user name states. I'm in the middle of building a new "street sleeper" caprice 4 door sedan. I know it's not a hotrod so to speak but hey. I used to have a 77 sedan with a 330hp 350 before this new one, but sold it to make way for other things. Now i have an 80 sedan which i'm building a SBC for, hence my posting here and the question!

I'm gonna use a 2 bolt mains 78 engine block as a basis for a 383 cubic inch stroker. Using a forged crank and rods with forged pistons.

Q 1. Whats the best compression ratio to have in this motor?
Q 2. What heads do i use iron or aluminum and valve sizes ect?
Q 3. Whats the best cam durations?
Q 4. Whats the best carb to use i was thinking of a 600?

The car weighs about 4000lbs and is stock (and real tidy) I want torque and lower RPM HP due to the TH350 and 2.41:1 rear end, plus i drive the car on the streets everyday (in the summer) Here in the UK we have regular (premium) gas thats 95 octane. So tell me guys whats the best setup on this motor gonna be??? an what the HP and LBF to go with that (estimate)

Cheers for any help here, as i have never built a stroker..
