Has anyone used it in a 383? Was it a good low-mid street cam, and what did you have for manifold vacuum at idle? Thanks. Is this for the car in your sig, a 4 speed ? If so get the 6401 , I ran that in my 69 bee , 130k mile 383-2bbl long block with a DP4B , 3.23 gear , 4speed , power brakes , did 97mph in 1/4 at 3900 lbs , not earth shattering but the car was fun to drive. Okay. Did you have to change the valve springs, or did it work with original springs? Thanks. 68 Roadrunner. 383 4-spd. Beat up.
