b303 with speed density
 

basicly will this setup work the b303 cam with speed density and possibly 1.6 rr what problems will i be looking at and is it hard to tune i also will be instaling edelbrock heads gt40 intake fp regulator and full mac exuast.

Try 1.7 roller rocker and the stock cam with your heads and intake. The stock is a lot better than what most people think and a safer for your speed density set up. The B cam could work well, but be prepared to some tuning headache. You will need to adjust the fuel pressure, idle speed, tps. I will maybe put the b cam in my car but my combo is less free flowing than yours. Good luck!

88workcar was running almost the exact same combo as what you are suggesting, but lose the stock upper. It's still restricting you, even with extrude honing.

I don't believe he had much issue with tuning his car.

im not doing this setup on my car im doing it for a friend on his car were gonna put a gt40 intake on it. Does anyone know what fuel pressure i should run how i should set my tps or where my idle should be and also timing
